CAUTION
Because all electronic components are
sensitive to the effects of electrostatic
discharge
(ESD)
damage,
correct
procedures should be used when
handling all components in this kit and
inside the supporting personal computer.
Use the following procedures to minimize
the likelihood of damage due to ESD:
– Always handle all static-sensitive
components only in a protected area,
preferably a lab with conductive
(anti-static) flooring and bench
surfaces.
– Always use grounded wrist straps
when handling sensitive components.
– Never remove components from
anti-static packaging until required for
installation.
– Always transport sensitive
components in anti-static packaging.

Installing the Software
The DSP56009EVM demo software includes the following:
• Motorola diskette containing:
–
Demonstration code (passthru, sfpevm09, example)
• Domain Technologies diskette containing the windowed user interface debug
software
Use the following steps to install the software:
1. Insert the Motorola software diskette into the PC diskette drive.
2. If the system is not already running in Windows, start Windows.
3. From Windows, select a DOS window and run the install program. The
general format for the command line of the install program is
install <source>. For example, if your diskette drive is the a: drive, type in
a:install a:. The program installs the software in the default destination
c:\evm56007.
4. Close the DOS window and remove the Motorola software diskette from the
diskette drive. Insert the Domain Technologies diskette labeled Debug-56K
into the drive.
5. From Windows, run the Debugger installation program install.exe on the
diskette. This can be done from the Microsoft Windows Program Manager by
pulling down the File menu, choosing Run, entering a:install on the
command line, and clicking OK.
6. Read the README.TXT if you are installing the Debugger program for the
first time. This provides information in addition to that provided by the
Domain Technologies manual included with this kit.
7. The install program creates a program group called EVM56007 and a program
icon called EVM56007 within Windows. This step completes the software
installation.

Evaluation Module Theory of Operation
Inputs and Outputs
Refer to Section 4, 56009EVM Schematics, for reference to pinouts and jumper
configurations.
2.1
INPUTS AND OUTPUTS
Analog signals connected to the Evaluation Module inputs are converted to 20 bit
data at the ADC. U19 and U20 attenuate the signal and convert it to Balanced mode.
The ADC has the Select Serial I/O Mode (SMODE) pin pulled high to make the ADC
the SAI receive clock master. When the ADC is in Master mode, the ADC’s Serial
Data Clock (SCLK) and Left/Right Select (L/R) word clock pins are outputs. The
L/R word clock output is the opposite polarity of I2S. It is inverted in the
Programmable Logic Device (PLD) to create true I2S. The ADC receives its
oversampling clock on the Digital Section Clock Input (ICLKD), which is then
internally divided by two, and this signal is provided to the Analog Section Clock
Input (ICLKA). ICLKD can be driven from the 11.2896 MHz clock, the 12.288 MHz
clock, or the 256 × Fs clock produced by the CS8412 AES/EBU Receiver. The Audio
Power Down input (APD) and Digital Power Down input (DPD) pins are wired to
the Cntl_Mute signal of the PLD. When pulled high, the ADC will be muted. When
first pulled low, the ADC will be reset, then it will be enabled.
The other possible input source comes from the SPDIF inputs (J14 for electrical input
and J17 for optical input). Jumper JP4 selects the source (see Table 2-1 below). When
receiving valid SPDIF input, the SPDIF Receiver drives the Master Clock (MCK)
output that is 256 times the Frame Sync frequency of the received data. The CS8412
operates in Mode 3, the I2S Slave mode.

Clock Select
The Evaluation Module provides a means for the user to select which clock controls
the reception and transmission of digital audio (see Table 2-2 below). JP2 selects the
ADC and DAC clocks which, when jumpered, are set at 44.1 KHz and, when not
jumpered, at 48 KHz. The expansion connector, J5, can be used to directly access the
DSP. The receive SAI bus may be clocked by the selection made at JP2 (44.1 KHz or
48 KHz) or be clocked by the received SPDIF signal. The transmit SAI bus may be
clocked by either the clock selected at JP2 or by the received SPDIF signal. It is the
user’s responsibility to ensure that data is output at the desired rate. See Table 2-2,
below.

Serial Audio Interface (SAI)
The DSP56009 SAI transmitter drives the six analog outputs and the SPDIF output.
I2S is the Default mode for the DACs. The Master Clock (MCLK) rate for the DACs is
256 × Fs. The dual RC networks after the DACs serve as AC couplers for audio data,
2-4
DSP56009EVMUM
MOTOROLA
Evaluation Module Theory of Operation
Inputs and Outputs
and as low-pass filters to convert the delta-sigma digital output pulses to analog
waveforms.
The digitally controlled analog domain attenuators receive the audio data and
attenuate or amplify the data as determined by the microcontroller. The attenuators
receive the Serial Clock input (SCLK), Serial Data Input (SDATAI), and the Chip
Select/latch (CS) from the microcontroller.
2.1.3
Sony-Philips digital interface format (SPDIF)
The SPDIF transmitter receives data from the DSP through the Serial Data input
(SDATA) using the Frame Sync (FSYNC) and the Serial Data Clock (SCK). The
transmitter outputs SPDIF audio signals through J15 (electrical) and J16 (optical).
Fs_sens from the clock select appears at the expansion connector in order to read the
sampling rate with the DSP’s General Purpose I/O (GPIO1) at J5.41 and also at U21-2
to select the state of the ‘sample-rate’ bits transmitted within the channel status block.
See the SPDIF specification for more information. The channel status bits and block
sync signals (DRcv_Blk, DTrn_Blk, DRcv_CS, and DTrn_CS) are available at J5.43 to
allow the DSP to read one of them, as well. Isolation transformers are used on both
input and output, although they are not strictly required for SPDIF because this
Evaluation Module is intended to be used as a development system.
2.1.4
Other inputs and Outputs
The clock master is derived from one of two sources: the 11.2896 MHz clock or the
12.288 MHz clock. The microcontroller also receives commands from either the soft
switches (S1, S2, S3, or S4) or from the Keypad Expansion Port, J18. The current user
screen or the results of these commands are then displayed by a modular LCD panel
with a 2 × 16 character display. The microcontroller code is capable of driving larger
LCD displays, but all user screens are designed for a 2 × 16 character display.
The MC68HC711E9 communicates with the DSP via the Serial Host Interface (SHI)
port in SPI mode. When SS is pulled low, the microcontroller can write to the DSP.
The MOSI and MISO lines pass control data through the DSP SHI in 24-bit mode.
SCK is the SPI Shift Clock from the DSP. Again, the expansion connector, J5, can be
used to access or intercept host port communications.

Operating Mode Selection
DSP56009EVM modes can be selected at JP3, as shown in Table 2-3. Once the mode
has been selected, the PLD can receive interrupts from the network attached to J19.

2.1.6
OnCE™ Port
The OnCETM port interface operates by receiving the serial data from the RS-232
Transceiver and executing commands sent by the host computer. These commands
can reset the DSP, put the DSP in Debug mode, release the DSP from Debug mode,
read and write to the OnCETM port, and read and write to the DSP itself. The serial bit
rate is 19,200 bits/second. The RS-232 serial communications are performed in
software on the MC68705K1. Port A of the MC68705K1 communicates with the DSP,
and Port B communicates with the host computer. The acknowledge signal from the
OnCETM port is a low-going pulse on DS0. Since the 68705K1 is too slow to reliably
2-6
DSP56009EVMUM

catch this very narrow pulse, the pulse is latched in the PLD and the output of the
latch appears on the ACK pin (PA2). When this occurs, the 68705K1 illuminates red
LED D5 to indicate that the DSP is in the Debug mode. For more information on the
OnCE port, see the DSP56000 Family Manual. The reset switch will reset the
microcontroller, which will subsequently reset the DSP56009. The MC68705K1
source and object code are available from the Motorola DSP Division; contact your
local Motorola FAE.
2.1.7
RS232 Connections and JP1
RS-232 is an often-abused standard, and the direction of the signals present on pins 2
and 3 of the DB9 connector do not always conform to the standard. JP1 provides the
user with the ability to reverse these two pin connections without resorting to NULL
Modem adapters or rewiring cable connectors. As shipped, JP1.1 is connected via
shorting jumpers to JP1.3 and JP1.2 is connected to JP1.4. This connects J4.2 to the
OUTPUT of the Evaluation Module’s RS-232 level converter (U4) and J4.3 to the
INPUT of the board’s RS-232 receiver. These directions can be reversed by
reorienting the shorting jumpers and turning them 90 degrees (one-quarter turn),
thereby connecting JP1.1 to JP1.2 and JP1.3 to JP1.4. The user should never need to
rewire an RS-232 connector in order to establish Evaluation Module communications
with a host computer.
2.1.8
Operating Modes and SRAM refresh in the 56009
In Modes 0, 1, 2, and 3 the SRAM is refreshed from the nvRAM and the DSP can
bootstrap from the SRAM via the EMI if a valid Bootstrap mode is used. When in
Modes 4, 5, 6, and 7 the SRAM is not refreshed. Refreshes are not affected by jumpers
on the expansion connector, J5. Jumpers J5.37 and J5.39 must be inserted to have full
DSP control of the SRAM and nvRAM after bootstrap.

Evaluation Module Theory of Operation
Inputs and Outputs
2.1.10
Power Supplies
The Evaluation Module requires power sources, for both analog and digital circuits,
in order to operate. Bipolar analog power (use a linear power supply for best results)
is received through screw terminals at J3. Digital power is received through screw
terminals at J2 or via a 2.1mm connector (J1). When the power is on, D6 (green LED)
is illuminated. Analog power input may be 8 to 12 volts and digital power input may
be 8 to 15 volts. While the voltage regulator can accommodate higher input voltage
potentials, the added heat dissipation required at these input voltage levels will
result in the regulator becoming dangerously warm, and it is not recommended that
the user subject the board to power inputs in excess of the maximum levels listed.
Note:
2.1.11
Always supply the Evaluation Module with analog power prior to or
simultaneous with the application of digital power. If digital power is
supplied before the analog power, the DACs may go into one of three
possible error modes (no long-term damage to the device will occur), and
will not function correctly. If analog power is supplied first, or if both
analog power and digital power are applied simultaneously, these
problems do not appear and the DACs are properly initialized.
Memory
The Evaluation Module has 8192 bytes each of fast Static RAM (SRAM) and of
nonvolatile RAM (nvRAM). The SRAM operates at zero wait states at a 40 MHz DSP
clock speed, one wait state at 50, 66 MHz and two wait states at 81 MHz. The contents
of the SRAM may be block-loaded into nvRAM and the contents of the nvRAM may
be block- loaded into the SRAM. The lowest 3072 bytes of the nvRAM may also be
used to store code to load into the DSP via EMI bootstrap.

CS5390 Stereo ADC
The following section describes the various peripheral devices used on the
DSP56009EVM and includes any necessary equations and information. Contact
information for the manufacturers of significant peripheral devices is included along
with the parts listing in Section 5.
3.1
CS5390 STEREO ADC
The CS5390 is a complete Analog-to-Digital Converter (ADC) for stereo digital audio
systems. It performs sampling, analog-to-digital conversion and anti-alias filtering,
generating 20-bit values for both left and right inputs in serial form. The output word
rate can be up to 50 kHz per channel.
The CS5390 uses fifth-order, delta-sigma modulation with 64 times oversampling
followed by digital filtering and decimation, which removes the need for an external
anti-alias filter, beyond the simple balanced RC filter formed by R25, R26, and C8
(R31, R32, and C20 for the right channel).
The ADC uses a differential architecture that provides excellent noise rejection. The
CS5390 has a filter passband of DC to 21.7 kHz. The filters are linear phase, have
0.005 dB passband ripple, and greater than 100 dB stopband rejection. The operating
temperature range is 0o to 70o.

CS4331 STEREO DAC
The CS4331 is a complete stereo Digital-to-Analog Converter (DAC) with 18-bit
resolution, including interpolation, 1-bit digital-to-analog conversion, and output
analog filtering in an 8-pin package. The CS4331 is based on delta-sigma modulation
where the modulator output controls the reference voltage input to an ultra-linear
analog low-pass filter. This architecture allows for infinite adjustment of sample rate
between 1 kHz and 50 kHz while maintaining linear phase response, simply by
changing the master clock frequency. The CS4331 contains optional on-chip
de-emphasis and operates from a single +5 V power supply.
The CS4331 has a 96 dB dynamic range, less than 0.003% THD, low clock jitter
sensitivity and completely filtered line level outputs that use linear-phase filtering.

improved by the use of this type of transformer. The transformer’s ratio is 1:1,
primary inductance is 600 µH, inter-winding capacitance is 1.1 pF, bandwidth is 16
kHz to 100 MHz, and rise-time is 3 ns.

OVERVIEW
This section contains an example that illustrates how to develop a very simple
program for the DSP56009. This example has been designed for users who have little
or no experience with the DSP development tools. The example demonstrates the
form of assembly programs, gives instructions on how to assemble programs, and
shows how the Debugger can be used to verify the operation of programs.
The rounded blocks represent the assembly and object files. The white blocks
represent software programs to assemble and link the assemble programs. The gray
blocks represent hardware products. The following sections give basic information
regarding the assembly program, the Assembler, the Linker and the object files.
Detailed information about these subjects can be found in the Assembler and Linker
manuals provided with the Motorola DSP CLAS software package, available through
your Motorola sales office or distributor. The documentation is also available
through the Motorola DSP internet URL http://www.motorola-dsp.com.

WRITING THE PROGRAM
The following sections describe the format of assembly language source statements
and give an example assembly program.
6.2.1
Source Statement Format
Programs written in assembly language consist of a sequence of source statements.
Each source statement may include up to six fields separated by one or more spaces
or tabs: a label field, an operation field, an operand field, up to two data transfer
fields, and a comment field. For example, the following source statement shows all
six possible fields:
trm
mac
x0,y0,a
Label Operation Operand
x:(r0)+,x0
y:(r4)+,y0
X Data Transfer
Y Data Transfer
;Text
Comment
6.2.1.1
Label Field
The label field is the first field of a source statement and can take one of the following
forms:
• A space or tab as the first character on a line ordinarily indicates that the label
files is empty and that the line has no label.
• An alphabetic character as the first character indicates that the line contains a
symbol called a label.
• An underscore as the first character indicated that the label is a local label.
With the exception of some directives, a label is assigned the value of the location
counter of the first word of the instruction or data being assembled. A line consisting
of a label only is a valid line and has the effect of assigning the value of the location
counter to the label.
6.2.1.2
Operation Field
The operation field appears after the label field and must be preceded by at least one
space or tab. Entries in the operation field may be one of three types:
• Opcode—mnemonics that correspond directly to DSP machine instructions
• Directive—special operation codes known to the Assembler which control the
assembly process
6-4
DSP56009EVMUM
MOTOROLA
Example Test Program
Writing the Program
• Macro call—invocation of a previously defined macro which is to be inserted
in place of the macro call
6.2.1.3
Operand Field
The interpretation of the operand field is dependent on the contents of the operation
field. The operand field, if present, must follow the operation field and must be
preceded by at least one space or tab.
6.2.1.4
Data Transfer Fields
Most opcodes can specify one or more data transfers to occur during the execution of
the instruction. These data transfers are indicated by two addressing mode operands
separated by a comma, with no embedded blanks. If two data transfers are specified,
they must be separated by one or more blanks or tabs. Refer to the DSP56000 Family
Manual for a complete discussion of addressing modes that are applicable to data
transfer specifications.
6.2.1.5
Comment Field
Comments are not considered significant to the Assembler, but can be included in the
source file for documentation purposes. A comment field is composed of any
characters that are preceded by a semicolon.
6.2.2
Example Program
This program takes two lists of data, one in X memory, and one in Y memory, and
calculates the sum of the products of the two lists. Calculating the sum of products is
the basis for many DSP functions. Therefore, the DSP56009 has a special instruction
(MAC) that multiplies two values and adds the result to the contents of an
accumulator. This program is provided as example.asm on the DSP56009EVM demos
diskette and is placed in the EVM56007 directory by the installation procedure.

ASSEMBLING THE PROGRAM
The following sections describe the format of the Assembler command, give a list of
Assembler special characters and directives, and give instructions to assemble the
example program.
6.3.1
Assembler Command Format
The Motorola DSP Assembler is included with the DSP56009EVM on the Motorola
3-1/2 inch diskette and can be installed by following the instructions in
Section 1.4.3. The Motorola DSP Assembler is a program that translates assembly
language source statements into object programs compatible with the DSP56009. The
general format of the command line to invoke the Assembler is:
asm56000[options] <filenames>
where asm56000 is the name of the Motorola DSP Assembler program, and
<filenames> is a list of the assembly language programs to be assembled. The
following section describes the Assembler options. To avoid ambiguity, the option
arguments should immediately follow the option letter with no blanks between
them.
MOTOROLA
DSP56009EVMUM
6-7
Example Test Program
Assembling the Program
6.3.2
Assembler Options
-A
This option indicates that the Assembler should run in Absolute mode, generating an
absolute object file when the -B command line option is given. By default, the
Assembler produces a relocatable object file that is subsequently processed by the
Motorola DSP Linker.
-B<objfil>
This option specifies that an object file is to be created for Assembler output. <objfil>
can be any legal operating system filename, including an optional pathname. The
type of object file produced depends on the Assembler operation mode. If the -A
option is supplied on the command line, the Assembler operates in Absolute mode
and generates an absolute object (.cld) file. If there is no -A option on the command
line, the Assembler operates in Relative mode and creates a relocatable object (.cln)
file. If the -B option is not specified, the Assembler will not generate an object file. If
no <objfil> is specified, the Assembler will use the basename (filename without
extension) of the first filename encountered in the source input file list and append
the appropriate file type (.cln or.cld) to the basename. The -B option should be
specified only once.
Example: asm56000 -Bfilter main.asm fft.asm fio.asm
This example assembles the files main.asm, fft.asm, and fio.asm together to produce
the relocatable object file filter.cln.
-D <symbol> <string>
This option replaces all occurrences of <symbol> with <string> in the source files to
be assembled.
Example: asm56000 -DPOINTS 16 prog.asm
This example replaces all occurrences of the symbol POINTS in the program
prog.asm by the string ‘16’.
-EA<errfil> or -EW<errfil>
These options allow the standard error output file to be reassigned on hosts that do
not support error output redirection from the command line. <errfil> must be
present as an argument, but can be any legal operating system filename, including an
6-8
DSP56009EVMUM
MOTOROLA
Example Test Program
Assembling the Program
optional pathname. The -EA option causes the standard error stream to be written to
<errfil>; if <errfil> exists, the output stream is appended to the end of the file. The
-EW option also writes the standard error stream to <errfil>; if <errfil> exists, it will
be overwritten.
Example: asm56000 -EWerrors prog.asm
This example redirects the standard output to the file errors. If the file already exists,
it will be overwritten.
-F<argfil>
This option indicates that the Assembler should read command line input from
<argfil>. <argfil> can be any legal operation system filename, including an optional
pathname. <argfil> is a text file containing further options, arguments, and filenames
to be passed to the Assembler. The arguments in the file need to be separated only by
some form of white space. A semicolon on a line following white space makes the
rest of the line a comment.
Example: asm56000 -Fopts.cmd
This example invokes the Assembler and takes the command line options and source
filenames from the command file opts.cmd.
-G
This option sends the source file line number information to the object file. This
option is valid only in conjunction with the -B command line option. The generated
line number information can be used by debuggers to provide source-level
debugging.
Example: asm56000 -B -Gmyprog.asm
This example assembles the file myprog.asm and sends the source file line number
information to the resulting object file myprog.cln.
-I<pathname>
This option causes the Assembler to look in the directory defined by <pathname> for
any include file not found in the current directory. <pathname> can be any legal
operating system pathname.
Example: asm56000 -I\project\ testprog
MOTOROLA
DSP56009EVMUM
6-9
Example Test Program
Assembling the Program
This example uses IBM PC pathname conventions, and would cause the Assembler
to prefix any include files not found in the current directory with the \project\
pathname.
-L<lstfil>
This option specifies that a listing file is to be created for Assembler output. <lstfil>
can be any legal operating system filename, including an optional pathname. If no
<lstfil> is specified, the Assembler will use the basename (filename without
extension) of the first filename encountered in the source input file list and append
.lst to the basename. The -L option should be specified only once.
Example: asm56000 -L filter.asm gauss.asm
This example assembles the files filter.asm and gauss.ams together to produce a
listing file. Because no filename was given, the output file will be named using the
basename of the first source file, in this case filter, and the listing file will be called
filter.lst.
-M<pathname>
This option causes the Assembler to look in the directory defined by <pathname> for
any macro file not found in the current directory. <pathname> can be any legal
operating system pathname.
Example: asm56000 -Mfftlib\ trans.asm
This example uses IBM PC pathname conventions, and would cause the Assembler
to look in the fftlib subdirectory of the current directory for a file with the name of the
currently invoked marco found in the source file, trans.asm.
-V
This option causes the Assembler to report assembly progress to the standard error
output stream.
-Z
This option causes the Assembler to strip symbol information from the absolute load
file. Normally symbol information is retained in the object file for symbolic
references purposes. This option is only valid with the -A and -B options.
Note:
Multiple options can be used. A typical string might be:
Example: asm56000 -A -B -L -G filename.asm

Example Test Program
Motorola DSP Linker
6.3.4
Assembling the Example Program
The Assembler is a MS-DOS based program, thus to use the Assembler you will need
to exit Windows or open a MS-DOS Prompt Window. To assemble the example
program, type asm56000 -a -b -l -g example.asm in the evm007 directory created by
the installation process from Section 1.4.3. This will create two additional files:
example.cld and example.lst. The example.cld file is the absolute object file of the
program, and this is what will be downloaded into the DSP56009. The example.lst
file is the listing file and gives full details of where the program and data will be
placed in the DSP56009 memory.
6.4
MOTOROLA DSP LINKER
Though not needed for our simple example, the Motorola DSP Linker is also
discussed here in the DSP56009EVM User’s Manual. The DSP Linker may be
obtained through your Motorola sales office or distributor. The Motorola DSP Linker
is a program that processes relocatable object files produced by the Motorola DSP
Assembler, generating an absolute executable file that can be downloaded to the
DSP56009. The general format of the command line to invoke the Linker is:
dsplnk [options] <filenames>
where dsplnk is the name of the Motorola DSP Linker program, and <filenames> is a
list of the relocatable object files to be linked. The following section describes the
Linker options. To avoid ambiguity, the option arguments should immediately
follow the option letter with no blanks between them.
6-16
DSP56009EVMUM
MOTOROLA
Example Test Program
Motorola DSP Linker
6.4.1
Linker Options
-A
This option auto-aligns circular buffers. Any modulo or reverse-carry buffers defined
in the object file input sections are relocated independently in order to optimize
placement in memory. Code and data surrounding the buffer are packed to fill the
space formerly occupied by the buffer and any corresponding alignment gaps.
Example: dsplnk -A myprog.cln
This example links the file myprog.cln and optimally aligns any buffers encountered
in the input.
-B<objfil>
This option specifies that an object file is to be created for Linker output. <objfil> can
be any legal operating system filename, including an optional pathname. If no
filename is specified, or if the -B option is not present, the Linker will use the
basename (filename without extension) of the first filename encountered in the input
file list and append .cld to the basename. If the -I option is present (see below), an
explicit filename must be given. This is because if the Linker followed the default
action, it possibly could overwrite one of the existing input files. The -B option
should be specified only once. If the file named in the -B option already exists, it will
be overwritten.
Example: dsplnk -Bfilter.cld main.cln fft.cln fio.cln
In this example, the files main.cln, fft.cln, and fio.cln are linked together to produce
the absolute executable file filter.cld.
-EA<errfil> or -EW<errfil>
These options allow the standard error output file to be reassigned on hosts that do
not support error output redirection from the command line. <errfil> must be
present as an argument, but can be any legal operating system filename, including an
optional pathname. The -EA option causes the standard error stream to be written to
<errfil>; if <errfil> exists, the output stream is appended to the end of the file. The
-EW option also writes the standard error stream to <errfil>; if <errfil> exists it will
be overwritten.
Example: dsplnk -EWerrors myprog.cln
MOTOROLA
DSP56009EVMUM
6-17
Example Test Program
Motorola DSP Linker
This example redirects the standard error output to the file errors. If the file already
exists, it will be overwritten.
-F<argfil>
This option indicates that the Linker should read command line input from <argfil>.
<argfil> can be any legal operating system filename, including an optional
pathname. <argfil> is a text file containing further options, arguments, and filenames
to be passed to the Linker. The arguments in the file need be separated only by some
form of white space. A semicolon on a line following white space makes the rest of
the line a comment.
Example: dsplnk -Fopts.cmd
This example invokes the Linker and takes command line options and input
filenames from the command file opts.cmd.
-G
This option sends source file line number information to the object file. The generated
line number information can be used by debuggers to provide source-level
debugging.
Example: dsplnk -B -Gmyprog.cln
This example links the file myprog.cln and sends source file line number information
to the resulting object file myprog.cld.
-I
The Linker ordinarily produces an absolute executable file as output. When the -I
option is given, the Linker combines the input files into a single relocatable object file
suitable for reprocessing by the Linker. No absolute addresses are assigned and no
errors are issued for unresolved external references. Note that the -B option must be
used when performing incremental linking in order to give an explicit name to the
output file. If the filename were allowed to default, it could overwrite an existing
input file.
Example: dsplnk -I -Bfilter.cln main.cln fft.cln fio.cln
In this example, the files main.cln, fft.cln, and fio.cln are combined to produce the
relocatable object file filter.cln.

DSP56009EVMUM
MOTOROLA
Example Test Program
Motorola DSP Linker
-L<library>
The Linker ordinarily processes a list of input files, which each contain a single
relocatable code module. If the -L option is encountered, the Linker treats the
following argument as a library file and searches the file for any outstanding
unresolved references. If a module is found in the library that resolves an
outstanding external reference, the module is read from the library and included in
the object file output. The Linker continues to search a library until all external
references are resolved or no more references can be satisfied within the current
library. The Linker searches a library only once, when it is encountered on the
command line. Therefore, the position of the -L option on the command line is
significant.
Example: dsplnk -B filter main fir -Lio
This example illustrates linking with a library. The files main.cln and fir.cln are
combined with any needed modules in the library io.lib to create the file filter.cld.
-M<mapfil>
This option indicates that a map file is to be created. <mapfil> can be any legal
operating system filename, including an optional pathname. If no filename is
specified, the Linker will use the basename (filename without extension) of the first
filename encountered in the input file list and append .map to the basename. If the
-M option is not specified, then the Linker will not generate a map file. The -M option
should be specified only once. If the file named in the -M option already exists, it will
be overwritten.
Example: dsplnk -M filter.cln gauss.cln
In this example, the files filter.cln and gauss.cln are linked together to produce a map
file. Because no filename was given with the -M option, the output file will be named
using the basename of the first input file, in this case filter. The map file will be called
filter.map.
-N
The Linker considers case significant in symbol names. When the -N option is given
the Linker ignores case in symbol names; all symbols are mapped to lower case.
Example: dsplnk -N filter.cln fft.cln fio.cln
MOTOROLA
DSP56009EVMUM
6-19
Example Test Program
Motorola DSP Linker
In this example, the files filter.cln, fft.cln, and fio.cln are linked to produce the
absolute executable file filetr.cld. All symbol references are mapped to lower case.
-O<mem>[<ctr>][<map>]:<origin>
By default, the Linker generates instructions and data for the output file beginning at
absolute location zero for all DSP memory spaces. This option allows the
programmer to redefine the start address for any memory space and associated
location counter. <mem> is one of the single-character memory space identifiers (X,
Y, L, P). The letter may be upper or lower case. The optional <ctr> is a letter
indicating the High (H) or Low (L) location counters. If no counter is specified, the
default counter is used. <map> is also optional and signifies the desired physical
mapping for all relocatable code in the given memory space. It may be I for Internal
memory, E for External memory, R for ROM, A for Port A, and B for Port B. If <map>
is not supplied, then no explicit mapping is presumed. The <origin> is a hexadecimal
number signifying the new relocation address for the given memory space. The -O
option may be specified as many times as needed on the command line. This option
has no effect if incremental linking is being done (see the -I option).
Example: dsplnk -Ope:200 myprog -Lmylib
This example initializes the default P memory counter to hex 200 and maps the
program space to external memory.
-P<pathname>
When the Linker encounters input files, the current directory (or the directory given
in the library specification) is first searched for the file. If it is not found and the -P
option is specified, the Linker prefixes the filename (and optional pathname) of the
file specification with <pathname> and searches the newly formed directory
pathname for the file.The pathname must be a legal operating system pathname. The
-P option may be repeated as many times as desired.
Example: dsplnk -P\project\ testprog
This example uses IBM PC pathname conventions, and would cause the Linker to
prefix any library files not found in the current directory with the \project\
pathname.
-R<ctlfil>
This option indicates that a memory control file is to be read to determine the
placement of sections in DSP memory and other Linker control functions. <ctlfil> can
6-20
DSP56009EVMUM
MOTOROLA
Example Test Program
Motorola DSP Linker
be any legal operating system filename, including an optional pathname. If a
pathname is not specified, an attempt will be made to open the file in the current
directory. If no filename is specified, the Linker will use the basename (filename
without extension) of the first filename encountered in the link input file list and
append .ctl to the basename. If the -R option is not specified, then the Linker will not
use a memory control file. The -R option should be specified only once.
Example: dsplnk -Rproj filter.cln gauss.cln
In this example, the files filter.cln and gauss.cln are linked together using the
memory file proj.ctl.
-U<symbol>
This option allows the declaration of an unresolved reference from the command
line. <symbol> must be specified. This option is useful for creating an undefined
external reference in order to force linking entirely from a library.
Example: dsplnk -Ustart -Lproj.lib
This example declares the symbol start undefined so that it will be resolved by code
within the library proj.lib.
-V
This option causes the Linker to report linking progress (beginning of passes,
opening and closing of input files) to the standard error output stream. This is useful
to insure that link editing is proceeding normally.
Example: dsplnk -V myprog.cln
This example links the file myprog.cln and sends progress lines to the standard error
output.

-X<opt>[,<opt>,...,<opt>]
The -X option provides for link time options that alter the standard operation of the
Linker. The options are described below (* means default). All options may be
preceded by NO to reverse their meaning. The -X<opt> sequence can be repeated for
as many options as desired.

WEX
Add warning count to exit status
Example: dsplnk -XWEX filter.cln fft.cln fio.cln
This example allows the Linker to add the warning count to the exit status so that a
project build will abort on warnings as well as errors.
-Z
This option allows the Linker to strip source file line number and symbol information
from the output file. Symbol information normally is retained for debugging
purposes. This option has no effect if incremental linking is being done (see the -I
option).
Example: dsplnk -Zfilter.cln fft.cln fio.cln
In this example, the files filter.cln, fft.cln, and fio.cln are linked to produce the
absolute object file filter.cln. The output file will contain no symbol or line number
information.

INTRODUCTION TO THE DEBUGGER SOFTWARE
This section will give a brief introduction of the Domain Technologies Debugger,
detailing only that which is required to work through this example. Full details of the
Debugger and an informative tutorial can be found in the Debug-56K Manual. The
Domain Technologies Debugger is a software development system for the DSP56009.
The Domain Technologies Debugger is included with the DSP56009EVM on the
Domain Technologies 3-1/2 inch diskette and can be installed by following the
instructions in Section 1.4.3. To invoke the Debugger, double-click on the icon
labelled EVM56007 Debugger in the EVM56007 program group that was created
when the Debugger was installed.
The Debugger display will be similar to Figure 6-2, with the screen divided into four
windows: the command window, the data window, the unassembly window, and
the registers window (DSP56303EVM Debugger shown). The command window is
the window selected, which means that key strokes will be placed in the command
window. The command window is where commands are entered. The data window
is used to display DSP56009 data. The unassembly window is used to display the
DSP56009 programs. The next instruction to be executed will be highlighted. The
registers window shows the contents of the DSP56009 internal registers.

Introduction to the Debugger Software
Figure 6-2 Example Debugger Window Display
When the command window is selected as in Figure 6-2, the tool-bar at the top of the
screen contains buttons for the most often used commands. From right to left the
commands are: go, stop, step, jump, automatic update, reset and radix. The go button
runs the DSP56009 from the program counter. The stop button stops the DSP56009.
The step button executes a single instruction. The jump button is similar to the step
button, except that subroutines are treated as one instruction. The automatic update
button turns the automatic screen update mode on, so that the DSP56009 is
interrupted periodically to update the data and registers windows. The reset button
resets the DSP56009. The radix button can be used to change the radix of the selected
window. Other buttons will appear when other windows are selected, and the
function of these buttons can be found in the Debug-56K Manual.

6.6
RUNNING THE PROGRAM
To load the example program developed above into the Debugger, click in the
command window and type load example. The instruction at line 33 will be
highlighted in the unassembly window, as this will be the first instruction to be
executed. However, before we start to execute the program, we should check that the
values we expect to be in data memory are there. To do this, type display x:0 and
display y:0. The data will be displayed in the data window.
To step through the program, type step at the command window prompt. As a
shortcut, you can click on the step button or you can type the start of the command
and press the space bar, and the debugger will complete the remainder of the
command. To repeat the last command, simply press return. As you step through the
code, you will see the registers in the registers window being changed by the
instructions. After each cycle, any register that has been changed will be brightened.
Once you have stepped through the program, ensure that the program has executed
correctly by checking that the result in accumulator a is: $FE 9F2051 6DFCC2.
Stepping through the program like this is good for short programs, but it is
impractical for large complex programs. The way to debug large programs is to set
breakpoints. These are user-defined points at which execution of the code will stop,
allowing the user to step through the section of interest. To set a breakpoint in the
example to check that the values in r0 and r4 are correct before the do loop, type
break p:$106 in the command window. You will see the line before the loop brighten
in the unassembly window, indicating the breakpoint has been set. To point the
DSP56009 back to the start point of the program, type change pc 0. This changes the
program counter such that it is pointing to the reset vector. To start the program
running type go or click on the go button. The DSP56009 will stop when it reaches the
breakpoint, and you will be able to step through the remainder of the code.
To exit the Debugger, type quit at the command prompt.

Pass-Through Theory
A.1
PASS-THROUGH THEORY
The main program loop of the passthru.asm code serves as a reference guide on
how to pass data into and out of the EVM.
The following describes the operation of the passthru.asm program.
Audio samples are composed of left and right data words that are received and transmitted alternately. The RX_HERE bit is polled until it is set, indicating that a the left
data word is shifted in on the associated serial receive data pin (SDI0 or SDI1) and
transferred to the receive data register (RX0, RX1, or RX2). This bit is cleared after the
word is received.
The left receive interrupt service routine moves the word in the receive data register
into the receive buffer LEFT_AUDIN. The received word is also saved into another
register such as X1. The user's code may be inserted in this section to perform any
necessary audio processing.
The word to be transmitted out, stored in X1 is then moved into the LEFT_AUDOUT
transmit buffer. The left transmit interrupt service routine moves the word in the
transmit buffer into the transmit data register (TX0, TX1, or TX2) and it is shifted out
on the associated serial transmit data pin (SDO0, SDO1, or SDO2).
The right data is received and transmitted similarly. After the right word is received,
the RX_HERE bit is set in the right receive interrupt routine to indicate that the next
data to be received (left data) is a new sample.
The program loops back to the beginning of the main code to receive the next sample.
The illustration shown in Figure A-1 is the interrupt sequence for analog audio input.

Sound Field Processing Example
Introduction
B.1
INTRODUCTION
The phrase “sound field processing” seems to embody a sense of extra space added to
an original sound. With the advent of practical multichannel sound, processing certain
sound fields artificially became attainable and edifies the listening environment when
certain theaters or other settings are replicated in software. In order to create the delay
and reverberation elements that typify certain acoustical spaces, filtering and delay
components must be instituted. Therefore, DSPs ideally might handle even the
toughest simulation.
The soundfield processing example offered here is a design based around studies
performed independently by Manfred Schroeder and James Moorer1. Each provide
important insight into effective algorithms that create artificial reverberation. This
appendix will explain specifically the reverberation blocks inherent in one particular
example; however, this example provides only one of many as defined by Schroeder
and Moorer. This implementation uses filter coefficients collected by Schroeder that
imitate the Boston Concert Hall. A four channel output is generated: left front, right
front, left rear, and right rear; with a summed output feeding the center channel which
may also be lowpass filtered to be used for a subwoofer channel. The complete block
diagram of the system is shown in Figure B-8.
The software to implement this design is provided on the DSP56009 diskette for viewing/editing as SFPEVM09.ASM and for downloading onto the EVM as
SFPEVM09.CLD.The SFPEVM09.ASM may be operated with either a DSP56004,
DSP56007, or DSP56009.
The basic reverberation elements utilized in the file, SFPEVM09.ASM, include an early
reflection FIR filter for each of the four main channels and a reverberation unit
comprised of six parallel comb filters and a single all-pass filter.
This code as written can be implemented on the DSP56009EVM.
B.2
EARLY REFLECTIONS
Schroeder suggested a method for simulating early wall reflections and room
geometry by combining the direct summation of the original signal with a standard
unit reverberator to recreate late echos. The theory proposes that the first gains and
delays simulate the room’s geometry patterned after an FIR (non-recursive) filter
structure; and the unit reverberator/IIR (recursive) filter imitates the decay of the
reverberation once the pulses become inseparable.

Sound Field Processing Example
Early Reflections
Implemented in software, the algorithm takes advantage of the SAI (Serial Audio
Interface) and the EMI (External Memory Interface), two of the peripherals on
Motorola’s Symphony™ line of DSPs. The input samples are received by the SAI as
left and right channel data stored in memory. These samples are delayed several
milliseconds and retrieved according to the early reflection offset table
ER_off_buf. ER_off_buf is constructed as a seven-tap FIR section (See
Figure B-1). Table B-1 below illustrates the respective tap and its associated time
delay and gain as patterned after the Boston Concert Hall.

Twelve samples are read from the delay line(two channels, left and right, multiplied
by the offset table which is six deep) and four FIR filters are calculated. Reading of
the delayed samples is triggered by writing offset values to the EMI’s EOR0 and
EOR1 registers (as defined by the values in ER_DAx). The FIR filter creates the early
reflection defining the room size and reflective characteristics of the room
environment.
The FIR filter is implemented within a DO loop (instructions 33-70) in which the
offset information is retrieved by a post incrementing pointer, r4, and the left and
right data samples are read via the EDR registers. The DO loop is shown in
Figure B-1 below.

Sound Field Processing Example
Delay Line for Combs/Reverberation
The early reflection part is constructed such that the first EMI write transfer triggers
are performed in lines 13-14 before the DO loop; therefore, the first delayed EMI
read can occur after the first offsets are retrieved from X and Y memory in line 35
within the DO loop. Following the beginning of the DO loop, a trigger occurs (lines 37
and 39). In the next iteration of the DO loop the corresponding read occurs (lines 38
and 40). Therefore, the final EMI reads transpire at the termination of the loop in
lines 75 and 77 and the final left and right delay line samples are stored in X
memory (line 72).
Each time the loop executes, the left and right samples are multiplied by their
corresponding gains from ER_gains in pointer r1 (lines 43, 46) and routed to the
corresponding output. For instance, the comment in line 43, “; left from left”
signifies that the left FIR multiply is routed to the left output. The comment in line
46, “; left from right” likewise denotes that the right FIR multiply is routed to the
left output. This structure can be explicitly seen in Figure B-8 on page -14. The
pointer, r5, contains the input samples for the early reflections and the pointer, r4,
contains the delay values for the FIR as stated previously.
The block diagram of the early reflection is illustrated in Figure B-2.

DELAY LINE FOR COMBS/REVERBERATION
This portion of the code acts as the gathering point for the results of the four early reflection FIR blocks for the left front, right front, left rear, and right rear, respectively.
The saved values from each of these processes are summed with averaging weights
and stored in a delay line for use in the following comb filter and all-pass filter blocks,
B-6
DSP56009EVMUM

Sound Field Processing Example
Comb Filter
which generate the diffuse reverberation. The timing of the delay is designed to synchronize the inputs to the comb filter section. The summed value is routed to the
center channel.
B.4
COMB FILTER
Following the early reflections, there follows a section of six parallel comb filters that
create diffuse field reverberation. Recursive comb filters provide delay and incorporate feedback, which generate a “toothed” frequency response. Moorer determined
that the gain, g, should be a function of the reverberation time according to the
formula:
g = 1 - 0.366/T where T=reverberation time
(A.1)
The values of the optimal gain in the feedback loop, g1, are determined by the room
humidity versus distance from the source and the sample rate of the system. From
Moorer’s diagrams, the coefficients for a 44.1 kHz sample rate can be discerned.
Larger values of g1 will produce bright reverberation at the onset followed by a
muffled decay. The loopback gain, g2, can be determined by the equation
g2 = g(1-g1)
(A.2)
The total reverberation time for SFPEVM09.ASM is designed for two seconds. Therefore, using (A.1), the overall gain, g, is 0.83. The values of g1 for the seven-tap comb
filter model are shown in Table B-2 below.

B.5
ALL-PASS FILTER
The all-pass filter has a flat frequency response from 0 Hz to the Nyquist frequency;
however, the phase response delays different frequencies by different amounts. This
provides a very distinct sound approaching a phasing effect. Moorer defines the most
natural sounding unit reverberator to contain a number of comb filters and a single
all-pass filter. He also states that the use of more than six parallel comb filters and one
all-pass filter does not significantly enhance reverberant qualities. Therefore, only a
single all-pass filter is implemented here. The delay must be set to six milliseconds or
less, as longer delays produce what Moorer describes as an audible repetition. The
gain, constant g, of the all-pass filter is 0.7.
The block diagram for the all-pass filter is shown in Figure B-4.

De-Correlation Routine
The value z(n), which is the value of the upper gain stage, is computed first, the
delay z-m is accessed from the EDR0 (EMI Data Read register), and v(n) is
computed. The parallel move feature of Motorola’s DSP56K architecture allows this
arithmetic to be achieved in only four instructions, as shown in Figure B-5.

Figure B-5 All-Pass Filter Routine
In the above example, r6, points to the COMB_gains, r0 points to the EMI data read
register EDR0, and r4 points to EEcomb, which is the base addresses of the delays.
The final instructions in the routine store the all-pass output v(n) and the base address
(EBAR0) of the latest sample to be passed to the decorrelator and rear delay lines, as
shown in Figure B-6 below. A description of the de-correlator and delay line are
provided in B.6 De-Correlation Routine on page B-9.
The all-pass portion may be set to loop to allow for more multiple filter designs.
However, James Moorer states that this produces only a negligible increase in reverberant quality.
B.6
DE-CORRELATION ROUTINE
The data stream output from the main reverb routine is combined with each of the
separate early reflection values to provide the four discrete outputs: left front, right
front, left rear, and right rear. This routine takes the output of the first early reflection
value and decorrelates the signals from each of the other three channels. The de-correlation is performed by using all-pass filters with different coefficients to adjust the
phase of each channel independently.
The all-pass filter’s delay base and offset values and the gains are saved using pointers
r0 and r4 and then extracted as their manipulation occurs. The instructions:

save the front right and left base and offset values from the tables, EEapf_fr and
EEapf_fr and apf_fr_coeffs, respectively. Then the all-pass function is simply implemented as in B.5 All-Pass Filter on page B-8, utilizing the corresponding channel’s
delays (affecting phase only in an all-pass filter).
The de-correlation block diagram is shown in Figure B-6.

In order to adequately run the SFPEVM09.CLD file, a 256 kbyte 30-pin SIMM DRAM
must also be provided at connector U15. An audio source, an audio amplifier driving
headphones or speakers, and cables with RCA/phono connectors for five channels are
required to use the demo software. The SFPEVM09.CLD demo operates with five of
the six channel outputs shown in Table B-4 below.

In order to operate the sound field processing demonstration, open the Debug-EVM
and load the file, SFPEVM09.CLD. Once the object file has downloaded successfully,
type GO in the command window or click on the RUN icon. The demonstration
should now execute.
Macro commands that enable and disable the reverberation routines are provided
with the Sound Field Processing code. The command file, normal.cmd may be input
in the command window of the Domain Debugger as “normal” and the reverberation
will be effectively bypassed. Likewise, the command file, reverb.cmd may be input in
the command window as “reverb” to enable the sound field processor.

DSP56009EVM Multiplex Definition
Overview
C.1
OVERVIEW
Two DSP56009EVMs may be connected together to utilize the memory of two
Symphony DSPs. Six-channel data is multiplexed to SDI0 and SDI1, two of the SAI
transmitters on the DSP of the Transmit EVM. The data is then demultiplexed on the
DSP of the Receive EVM and available as discrete channels for post-processing of
certain decoding algorithms on the Transmit EVM. The file listen.cld must be
downloaded onto the Receive DSP in order to de-multiplex the serial audio stream.
The user’s DSP assembly files may be linked with this source file. A special cable
must be built in order to take advantage of this special function.
C.2
MULTIPLEX CABLE SPECIFICATION
The Mux cable must be connected from jumper block J5 on the Transmit board to J5 on
the Receive board. The cable must be no longer than seven or eight inches (preferably
six inches). There must be ground wires interspersed between each clock and data line
(those marked with an *). Ground connections can be found at pins 1, 2, 11, 12, etc. as
seen in the SRAM and External Memory Interface schematic. The cable must be a
ribbon cable split to carry the WST and SCKT signals and grounds physically separate
from the WSR, SCKR, SDI0, and SDI1 signals and grounds.

EVM SETUP FOR MULTIPLEXING
There are a few differences between the DSP56009EVM’s typical setup and the setup
for multiplexing. JP5 Jumpers must be off on both boards and the JP2 Jumper must be
connected. The SPDIF connector must be input to both boards with an AC-3 demodulated bit-stream.
