Application Development System
The Motorola Universal Command Converter is one component of a four-component
development tool for designing real-time signal processing systems. When combined with
a host card, a target board, and Motorola software and documentation, the universal
command converter becomes part of an advanced development tool called an application
development system (ADS). The ADS consolidates complex hardware and software
development tools within a low-cost workstation environment using a well-supported
operating system. By providing a solid foundation for application development and
testing, the ADS significantly reduces development costs and time to market. The versatile
ADS allows rapid initial development and supports comprehensive testing of prototype
designs. The ADS consists of the following four components:
•
Host-Bus Interface Board—a 16-bit ISA bus (for PC-workstations and HP700
workstations) and SBus (for Sun and SPARC workstations).
•
Command Converter (CC)— a universal design that supports all Motorola DSPs.
•
Control, Development, and Debugging Software—available in Windows®
compatible (Windows 95/NT 4.0), Sun OS compatible (Rel. 4.1.1 or later), Solaris
compatible (Rel. 2.5 or later), and HPUX compatible (Ver. 9.0 or 10.20).
•
Application Development Module (ADM)— supports development and testing
using a specific digital signal processor (DSP) chip. To identify currently available
ADMs, consult your local Motorola distributor, a Motorola semiconductor sales
office, or, for the latest information, Motorola’s DSP tools home page on the
Internet (http://www.mot.com/SPS/WIRELESS/dsptools).
For more information about ADS software, you can obtain a copy of the ADS User’s
Manual from the Development Tools CD included with the kit or from the following web
address:
http//:www.mot.com/SPS/DSP/documentation/tools.html
Motorola DSPs have a common On-Chip Emulation (OnCE™) module that gives
different development tools identical features. Using the concept of a common serial
debug port, one set of tools has been designed to allow a user to communicate with any of
the architectures using a single command converter. In some Motorola DSPs, this module
Motorola
Application Development System
1-1
General Description
uses a dedicated OnCE serial port to access the internal module. In other Motorola DSPs,
the internal OnCE module is addressed using the IEEE Joint Test Action Group (JTAG)
four-wire test access port (TAP) boundary scan architecture protocol. The tools software
can use either the direct OnCE serial port or the JTAG serial port.
This manual describes the installation, use, and functional description of the control
system that interacts with the target DSP.
1.1 General Description
The ADS is a tool for designing, debugging, and evaluating DSP-based systems. It
consists of three hardware circuit boards, as illustrated in Figure 1-1, and two software
programs. The hardware circuit boards are the host-bus interface, the command converter,
and the ADM. The two software programs are the ADS user interface program, which is
executed on the host computer, and the command converter monitor program which is
expected on the command converter. Figure 1-1 illustrates the ADS being used as a
hardware evaluation tool or host software accelerator. The ADM card has a 14-pin
connector, which provides an access point for the command converter JTAG/OnCE
interface.

Operating Environment
Figure 1-1 also illustrates how the ADS can be used as an emulator for a defined target
system whose hardware or software the user needs to debug. Here the user must provide
an access point on the target hardware for a 14-pin JTAG/OnCE interface cable, which
may be as simple as a 2-row × 7-set of test points. Chapter 3, "Functional Description,"
provides complete details of the pinout on the JTAG/OnCE interface cable.
The ADS software program provides routines the user needs to communicate with the
target DSP on the ADM or the target application. This program has a group of powerful
commands that enable the user to perform a variety of tasks. Operating system command
calls may be made from within the program, or temporary exits to the operating system
may be made without disturbing current set-ups with the target DSP.
For more information about the above paragraph, refer to the ADS User’s Manual which
can be found on the Development Tools CD included with the kit or at the following web
address:
http//:www.mot.com/SPS/DSP/documentation/tools.html
The Host interface board provides a physical link between the HOST computer and the
Command Converter via a parallel data and control bus cable. The parallel data path is
used for high-speed data transfers. The control bus signals enable the HOST computer to
reset, interrupt, and send commands to Command Converter simultaneously or
sequentially. The command converter then sends the reset, intercept, and various
commands to the ADM via the JTAG/OnCE cable.
The ADM is the basic platform for evaluating the DSP. It contains a DSP chip with a
JTAG/OnCE interface connector to configure it as a slave to the HOST computer or as a
stand-alone unit. In the slave configuration, the user controls the DSP processor and is
able to interrogate its status. This enables the user to debug hardware and software easily.
In the stand-alone configuration, a user program resident in ROM controls the ADM and
may be used as a prototype system for an end product.
1.2 Operating Environment
The ADS hardware and software is currently supported on the following three host
computers:
•

ISA expansion slots. A single PC-workstation interface card can control up to eight
command converters.
2.1.1.1 Installing the PC-Workstation’s Interface
Warning
Before removing or
installing any equipment
in the PC-workstation
computer, turn off the
power and disconnect the
power cord.
Refer to the appropriate installation and set-up manual for your PC-workstation for
instructions on removing the system cover.
Jumper group JG1 selects the interrupt asserted on the host processor by the host interface
card when the target DSP device makes a service request (for example, by reaching a
breakpoint).
Note:
The ADS software does not support interrupts. No jumper should be placed on
JG1 when used with the ADS software.
Jumper group JG2 specifies the host interface card I/O address. The host interface card
supports 16-bit I/O addresses and uses three consecutive addresses from the specified
address. The starting address may be configured, with jumper pairs A8–A15 in JG2, to
any multiple of $100, up to $FF00. Place a jumper over a pair of pins to set that address bit
to 0; remove the jumper to set the address bit to 1. Address bits A0–A7 are not decoded. In
Figure 2-2, the selected address range is $100–$102.
Note:
Although the host interface card supports 16-bit addressing, the ADS software
only supports addresses $100, $200, and $300.
Once you have ensured that the selected address does not conflict with another expansion
card installed in the motherboard, you may install the host interface card. Figure 2-2
illustrates the physical locations of JG1 and JG2.

The host interface card resides in the PC-workstations I/O bus; the ADS user interface
software communicates with the card through this I/O address block. The host interface
card address block may be changed to start at one of three addresses as described in
Table 2-1.

If the host interface card address block is changed from the default $100, the selected
address must be specified to the ADS. This may be done in one of the following three
ways:
•
Set the environment variable ADMADDR:
>SET ADMADDR=200
•
Issue the ADS command HOST:
> host io 200
•
Use the -d option on the ADS command line:
>ADS56300 -d 200
To install the host interface card properly, position its front bottom corner in the plastic
card guide channel at the front of the PC-workstation chassis. Keeping the top of the host
interface card level and any ribbon cables out of the way, lower the card until the card
connectors are aligned with the PC-workstation system board expansion slot connectors.
Using an evenly distributed pressure, press the host interface card straight down until it
seats in the expansion slot.

Host Computer Interface Card
Secure the host interface card to the PC-workstation chassis using the bracket retaining
screw. Refer to the PC-workstation installation and set-up manual for instructions on
reinstalling the cover.
The host interface card is factory-configured for no interrupts and address decoding at
$100–$102 of the PC-workstation I/O address map, which are undefined peripheral
addresses.
Note:
Jumper JG2 should be left disconnected.
2.1.2 Installing the PC-Workstation Software
A GUI debugger program that supports multiple windows, menus, and dialog boxes is
available for use in the Microsoft Windows environment.
2.1.2.1 Defining Environment Variables
The following sections specify environment variables which may need to be defined to
establish the correct operating environment for the ADS user interface software. These
environment variables may be defined during system start-up by adding lines to the file
c:\autoexec.bat, which applies to all versions of DOS and WINDOWS operating systems.
Some Windows 95 installations may not use the autoexec.bat file. If it does not exist, it
may be created and the SET commands inserted.
The general form of the SET command is as follows:
SET
symbolname=value
Use the names and values from the sections below, and do not use spaces around the “=”
sign.
If the I/O address of the host interface card is changed from the default setting of $100, the
ADS user interface program must be informed of the address to access the card. This may
be done with the environment variable ADMADDR:
set admaddr=200

2.1.3 SUN 4 to Command Converter Interface
The Motorola SBus/ADS Interface board is designed to be installed in an SBus slot on a
Sun SPARC station or compatible workstation. The board provides a parallel
communication path between the workstation and a Motorola DSP development system.
2.1.3.1 Installing the Sun-4 Interface
The Motorola SBus/ADS Interface is delivered ready to install in your SBus system.
There are no user-configurable jumpers or hardware configurable options. Please consult
the “SPARC station xxx Installation Guide” or the board installation instructions supplied
with your SBus system for installation details. Following is a summary of the instructions
in the Sun manual:
1. Save all open files, then shut down your system with the following series of
commands:
hostname% /bin/su
Password: mypasswd
hostname# /usr/etc/halt
Wait for the following messages:
Syncing file systems... done
Halted
Program Terminated
Type b(boot), c(continue), n(new command mode)
2. When these messages appear, you can safely turn off the power to the system unit.
Turn off power to the system, but keep the power cord plugged in. Open the system
unit. Be sure to attach a grounding strap to your wrist and to the metal casing of the
power supply. Follow the instructions supplied with your system to gain access to
the SBus slots.
3. Remove the SBus slot filler panel for the desired slot from the inner surface of the
back panel of the system unit. Note that the Motorola SBus/ADS Interface board is
a slave-only board and thus will function in any available SBus slot.
4. Slide the SBus board at an angle into the back panel of the system unit. Make sure
that the mounting plate on the SBus board hooks into the holes on the back panel of
the system unit.

gently press the corners of the board to seat the connector firmly.
6. Close the system unit.
7. Connect the 37-pin ADM interface cable to the SBus/ADS Interface board and
secure.
8. Turn power on to the system unit and check for proper operation.
2.1.3.2 Software Installation
The distribution CD included with the ADS package contains the “mdsp” SBus device
driver for the ADS as well as the ADSxxx user interface program for the ADS. The
following steps will allow you to install the device driver and run the user interface.
Note:
In the instructions that follow, ADSxxx represents the name of your particular
system, such as ADS56000, etc.
1. Copy all of the software from the distribution CD onto your system using
uncompress and tar. See the “readme” file for details
2. Install the driver with the following commands:
hostname# cd adsxxx/driver
hostname# make install
3. After a successful installation, you should see a module status message indicating
that your module was successfully loaded and giving its ID. To see this status at
any time, issue the “modinfo” command on SOLARIS, “modstat” for SunOS.
4. If the ADSxxx driver module was loaded properly, you should be ready to run the
ADSxxx user interface:
hostname# cd ../bin
hostname# adsxxx
If for any reason you wish to uninstall the driver, use the following commands:
hostname# cd adsxxx/driver
hostname# make unload (SunOS 4.x)
hostname# make uninstall
(SOLARIS 2.x)
2.1.4 HP7xx to Command Converter Interface
The Motorola HP7xx Interface uses the same ISA card installed in the PC-workstation. It
is controlled by an HPUX device driver. The HP7xx computer must have an ISA slot
available for plugging in this card. Older versions of the HP700 series computer did not
have ISA expansion slots. The ISA board provides a parallel communication path between
the HP workstation and a Motorola DSP development system. For details on jumper

Host Computer Interface Card
configurations of the ISA card, refer to Section 2.1.1, "PC-Workstation to Command
Converter Interface."
The HP7xx device driver and user interface program support multiple host interface cards
in a system. Therefore, when reading the software installation instructions keep in mind
that the device driver name(s) must be different for each card installed in a system.
2.1.4.1 Installing the HP-7xx Interface
Before installing one or more ISA cards, a sequence of steps must be followed to shut
down your system. If you are using HP VUE, carry out the first four steps of
Section 2.1.4.1.1, "HP VUE Shut-Down." If you are using the HP-UX command line
shell, carry out the first four steps of Section 2.1.4.1.2, "HP-UX Command Line Shell
Shut-Down."
To shut down your computer you must first be logged in as “root”. Save all open files
before shutting down, and always follow the proper shutdown procedure before turning
off the power to your workstation. Failure to do so could cause damage to files.
Note:
“hostname#” represents the system prompt; that is, it is not to be entered as part
of the command.
2.1.4.1.1 HP VUE Shut-Down
1. Use the HaltSystem application, located in the System_Admin file of the General
toolbox, by double-clicking on its icon.
2. Click on the “OK, Halt System” button to initiate shut-down.
3. When the message “Halted, you may now cycle power” appears, you may safely
turn off the power to your workstation.
4. Go to step 1 of Section 2.1.4.1.3, "ISA Card Installation."
2.1.4.1.2 HP-UX Command Line Shell Shut-Down
1. Change to the root directory with the following command:
hostname# cd /
2. Enter this command to initiate shut-down:
hostname# /etc/shutdown -h 0
3. When the message “Halted, you may now cycle power” appears, you may safely
turn off the power to your workstation.
4. Go to step 1 of Section 2.1.4.1.3.
2.1.4.1.3 ISA Card Installation
The following steps should be used to install the ISA card:
Motorola
Preparation and Installation
2-7
Host Computer Interface Card
1. Remove the power cord from both the wall socket and the unit.
2. Remove the power supply cover plate located on the rear of the unit and marked
“TO ACCESS EISA PULL THIS HANDLE”, and gently slide the EISA Adapter
Card Assembly (hereafter called “assembly”) out of the unit. See Figure 2-3.
3. Remove the blank EISA slot cover from the assembly. The cover is simply a piece
of metal that covers the hole when there is no card installed and is held in place by
a single screw. Be sure to save this screw as it will be used to secure the card.
4. Carefully slide the ISA card into the assembly, making sure that the connector pins
on the assembly meet up properly with those on the card, and that the cable socket
is positioned fully within the hole. Use the screw saved from the previous step to
securely attach the card to the assembly.
5. Carefully slide the assembly back into the unit. Press firmly on all four corners to
ensure that the connectors on the front of the assembly fully engage with those
inside the unit.
6. Reinstall the power supply cover plate, and then reconnect the power cord to both
the unit and the wall socket. Also connect the 37-pin ribbon cable from the ISA
card to the ADM board.
7. The system may now be restarted.

2.1.4.2 Installing the HP-7xx Device Driver
An HP-700 formatted CD-ROM contains the necessary files for the installation of the
device driver. The device driver supports multiple cards so only one device driver needs to
be installed regardless of the number of cards being used. This CD is UNIX tar formatted
and should be read in with the following command:
tar xvf /dev/rmt/0mn
An alternate command would be
2-8
Universal Command Converter
Motorola
Host Computer Interface Card
tar xvf /dev/rmt/0m
The number at the end of the command is the device number and should be changed if the
CD drive number is different on the machine being used. After the files are extracted from
the CD-ROM, a directory named “driver” is created.
The user must be logged in as “root” or superuser to proceed from this point. The
following steps should be followed for proper installation of the driver program:
Note:
“hostname#” represents the system prompt; that is, it is not to be entered as part
of the command.
The HP device driver for the ADS supports multiple host interface cards (up to three,
limited by the addresses that can be selected on the host interface card) installed into a
single HP-700 workstation.
1. When the files were installed, a directory called driver was created in the hierarchy.
Make this the current directory now by executing the following command, where
ADS-PATH is the path to where the ADS files were installed:
hostname# cd
/ADS-PATH/driver
2. Copy and change the ownership, group and mode of the device driver library file,
libmdsp.a, using the following commands:
hostname#
hostname#
hostname#
hostname#
cp libmdsp.a /etc/conf
chown bin /etc/conf/libmdsp.a
chgrp bin /etc/conf/libmdsp.a
chmod 444 /etc/conf/libmdsp.a
3. To install the device configuration file, type the following command. (Note that it
may be necessary to escape the ! by using a backslash \, depending on the shell you
are using.)
hostname# cp
!MOT0010.CFG
/etc/eisa
This copies the configuration file into the system EISA configuration directory.
Modify the copy of the file in /etc/eisa to reflect the I/O port that the card is
configured for (change the PORT entry).
If you are using multiple host interface cards in your HP, make multiple copies of
this file in /etc/eisa, changing the last digit of the file name on each copy. Modify
each copy to have the correct ID and PORT entries (the ID entry should be the
name of the file without the .CFG extension). Each PORT entry should be modified
to contain the proper addresses for the additional cards that are supported.
4. Run the EISA configuration program by typing this command:
hostname# /etc/eisa_config
Motorola
Preparation and Installation
2-9
Host Computer Interface Card
At the EISA prompt, type “add !MOT0010.CFG <slot num>”, where <slot num> is
the slot number in which the card is installed.
If you have installed multiple host interface cards, repeat the “add” command once
for each configuration file and slot. For example, if you created a file
MOT0011.CFG for a card in slot 2, and modified the PORT and ID entries in
MOT0011.CFG to reflect the I/O address of the card in slot 2, you would type add
!MOT0011.CFG 2" to add that card to the EISA configuration information.
On machines with one EISA expansion slot, the slot number is 1.
Press “q” to quit the EISA configuration program, and “s” to save.
5. You must now edit the /etc/master file to include the ADS device driver. Make a
backup copy of “/etc/master”. You will need to change one line and add three new
lines in this file. The entries will be in the “Third Party and User Drivers,” the alias
table, the driver/library table, and the library table.
Change the first available line of the “Third Party and User Drivers” section to look
like the following line. An available line is one which has dashes in the first four
entries. Note that the last two entries are already set and are not to be changed. The
last entry is the major number for the device. You may use a line with 38, 39, 40,
42, or 43 for the major number. Make note of the number you choose, as it is used
in the next step.
Name Handle Type Mask Block Char (Do not add this line.)
mdsp mdsp 1
1FA
-1 <major>
Find the alias table and add the following line:
mdsp mdsp
Find the driver/library table and add the following line:
mdsp libmdsp.a
Find the library table and add the following line:
libmdsp.a0
6. Make a device file for the driver by executing the following command:
hostname# mknod
/dev/mdsp0 c
<major> <minor>
The major and minor numbers of the device are given by <major> and <minor>,
respectively. N is a user chosen device group number. The ADS user interface
software always defaults to device group 0 or mdsp0.
Note:
2-10
The <major> must be the same major number you used in the previous step.
The minor number is 0x4S0000, where ‘S’ should be replaced by the card slot
number in which the card was placed (1 – n). For machines with a single slot,
Universal Command Converter
Motorola
Host Computer Interface Card
the slot number is 1. For example, slot 4 of a multi-slot machine would be
0x440000
Be sure to change the permissions for this file(s) by typing this command:
hostname# chmod
666
/dev/mdsp0
If you have installed multiple host interface cards, repeat the “mknod” and
“chmod”steps for each new card. The <major> number for each will be the same,
but the <minor> number will reflect the slot in which the card was installed. The
device file names are arbitrary, but you should make note of which card
corresponds to each device file name. We suggest using a final digit of “N– 1”for
slot “N”.
7. Edit the file /usr/sam/lib/kc/drivers.tx and add an entry for the ADS device driver.
You may wish to make a backup of the file before editing it. Add the following
line:
mdsp:::Out:Motorola ADS Host Interface Card
8. Select and edit a dfile (configuration description file). First, change directories by
executing the following command:
hostname# cd
/etc/conf
A dfile must now be selected. Your current system dfile should be called either
dfile, dfile.SAM (for a kernel that has been configured with the HP System
Administration Manager), or a unique name given by you if you have altered your
kernel configuration by hand. Use the dfile appropriate for your system. If you
aren’t sure which version to use, or if your choice doesn’t work, then you can use
the file created by the command
hostname# /system/TOOL/get_kdfile
/hp-ux > dfile.current
to get your current system dfile.
Make a back-up copy of the selected dfile and edit the selected dfile by adding the
following lines to the top of it:
* Motorola DSP ADS Device Driver
mdsp
9. Generate the files needed to rebuild the kernel with your new device driver.
Execute this command, replacing dfile-name with the dfile you selected in the
previous step:
hostname# /etc/config dfile-name
10. Generate a new kernel object file in the current directory using the following
command:
hostname# make
Motorola
-f
config.mk
XOBJS=libmdsp.a
Preparation and Installation
2-11
Configuring the Command Converter
11. If the build finished successfully, your new kernel may now be installed. Make a
backup of the current kernel by executing the following copy command:
hostname# cp
/hp-ux
/hp-ux.pre-ads
12. The final step is to install the new kernel in the root path and reboot the system.
Note the period before the first slash in the first argument of the cp command:
hostname# cp
./hp-ux
/hp-ux
To reboot the system using the new kernel, type the following command:
hostname# exec
reboot
During boot-up, you should see the following message displayed on the screen if
the installation was successful:
“Slot <slot-num>: Motorola DSP ADS Host Interface Card Initialized”
where <slot-num> is the previously selected slot number in which the card is
installed.
The ADS Device Driver is now installed and ready for use. By default, the ADS
program attempts to open the device file dev/mdsp0. If you want to use a different
device (i.e., different host interface card), you can specify the device file name in
an environment variable, or on the command line. The environment variable is
ADMADDR. The command line option is `-d', followed by the name of the device
file. The `-d' option must come before a command file name.
For example, to use /dev/mdsp2, you could set an environment variable before
invoking the ADS software using the following statements:
# setenv ADMADDR /dev/mdsp2
# adsXXXXX [command-file] (where XXXXX is the device)
or you can invoke the ADS software with a command line argument such as the
following:
# adsXXXXX -d /dev/mdsp2 [command-file]
2.2 Configuring the Command Converter
The universal command converter supports both the JTAG and OnCE serial protocols.
The universal command converter may be identified by the surface-mount DSP56002
which controls its operation. The monitor program resides in SRAM, and is downloaded
by the ADS software during command converter initialization and reset operations.
The universal command converter has two user-configurable jumper groups: JG2, which
selects the device number, and JG1, which selects the power source for the JTAG/OnCE
buffers.

2.2.2 JTAG/OnCE Port Buffer VDD
In order to provide support for low voltage DSPs (5V-2.7V), an advanced low voltage
CMOS buffer exists between the DSP56002 controller and the target JTAG/OnCE
interface cable. This buffer has its VDD pin connected to JG1, Pin 2. See Table 2-3 for
CMOS buffer VDD configuration.

The monitor code for the command converter, which is tailored for the target DSP family
in use, is provided with the ADS software. The code is downloaded automatically into the

Trouble Shooting the Command Converter
command converter during ADS system initialization and universal command converter
reset. If a revision is issued for the monitor firmware, an environment variable must be
defined to specify the filename of the revised monitor. The specified file will be loaded
into the command converter instead of the standard monitor program. The variable which
must be defined is CC56000, where “56000” is replaced with name of the DSP family in
use, and the defined value is the fully-specified filename of the revised monitor software.
For example,
•
DOS, in AUTOEXEC.BAT:
SET CC56300=C:\ADS\REVISIONS\MONITOR.LOD
•
UNIX, with C shell, in .login or .cshrc:
setenv cc56300 /ads/revisions/monitor.lod
•
UNIX, with Bourne shell, in .profile:
cc56300=/ads/revisions/monitor.lod
export cc56300
specifies that, for the GUI56300, the standard DSP56300 family universal command
converter monitor code is to be replaced by the code in the file
ADS\REVISIONS\MONITOR.LOD.
To verify that the monitor file is loading correctly, start the ADS program and enter the
following commands:
force s
display v
The monitor revision will be displayed. If the error ‘Unable to reset Command Converter’
is issued, make sure the correct path is specified in the definition of CC56x00.
2.3 Trouble Shooting the Command Converter
To ensure the command converter is connected correctly to the host card, there are several
commands that are directed specifically to the command converter. The first is:
cforce r
This command will reset the ADS chain throughout the host card, up to the command
converter. Another helpful command is:
cdisplay x:0#10
This command displays x memory locations 0 through 10 of the command converter. The
values in memory are irrelevant, the fact that memory from the command converter can be
read indicates that you are communicating correctly with the command converter. If these

two commands execute correctly, your ADS is working properly up through the JTAG
port on the command converter. If you are still having problems, there may be something
wrong with your 14-pin JTAG cable or target board.

Functional Description
The application development system (ADS) user interacts with the target DSP through
two subsystem components, the host computer interface and the command converter
controller. The host computer interface consists of a program written in the C language
that interacts with a host computer bus interface card. The command converter consists of
a program written in DSP56002 assembly language which interacts with the host
computer bus interface card and the target JTAG/OnCE port.
It should be noted that older versions of Motorola DSP products use the OnCE port
protocol, while newer versions of Motorola DSP products use the IEEE JTAG 4-wire
protocol to interact with their OnCE port. New versions of the command converter support
both JTAG and OnCE protocols.
Commands entered from the host computer’s keyboard are parsed and a series of low level
command packets are sent to the command converter. The command converter translates
these low level command packets into serial sequences that are transferred to the target
DSP via its JTAG/OnCE port. The JTAG/OnCE port provides the necessary control to the
target so programs may be loaded or saved, registers read or modified, and hardware
breakpoints set or cleared.
The host computer interface is designed to communicate with as many as eight command
converter cards. This requires a special software protocol to avoid data collisions between
one target and another. The purpose of this section is to describe the subsystem
components of the ADS to give a better understanding of the communication link between
the user and the target DSP.
3.1 Host Computer Hardware
The host computer’s hardware interface provides the communications link between the
user and the command converter. The ADS user interface program uses a software
handshake when communicating with the command converter. There are signals defined
on the host computer bus interface card which are used for requesting and acknowledging
information transfer. Since the handshake is software driven the transfer rate will be

dependent upon the host computer bus speed and its operating system. This section
describes the host computer interface hardware and software components.
3.1.1 Host Computer Bus Interface Card
Figure 3-1 shows a block diagram of the host computer interface card for all computer
platforms. The interface consists of three fixed addresses in the host computer I/O
memory map. The host computer’s interface card address zero is used as a control port for
selecting, resetting, or interrupting one or more command converters. Address one reads
and writes eight bit data bytes to one or more command converters. Address two
acknowledges command converter service requests and selects group members for
multiple command converter commands. All data is passed high-order byte first. For
example, in a 32-bit transfer, bits 31–24 are transferred first, followed by bits 23–16, bits
15–8, and then bits 7–0.

The ADS user interface program allows as many as eight command converters to be
addressed using one host computer interface card. Command converters may be addressed
in groups or individually depending upon the command and command arguments entered
by the user.
Host computer interface card address zero has eight output control lines. These output
control lines are asserted using positive logic (VOH = TRUE). Three address zero signals

Host Computer Hardware
(ADM_SEL0, ADM_SEL1, ADM_SEL2) select a command converter before sending a
command. Further information on the method of command converter selection is
discussed in subsequent sections.
Two handshake signals originate at the host computer and are used to pass data to and
from a command converter. HOST_REQ initiates a data byte transfer to a command
converter, while HOST_ACK acknowledges receipt of a data byte from a command
converter.
Two control signals (ADM_BRK,ADM_RESET) allow the user to assert an interrupt or a
reset exception on a single command converter or a group of command converters. The
ADM_BRK signal is used to put the command converter back into Command Entry mode;
the ADM_RESET signal is used to reset the command converter.
The command converter informs the host computer of target DSP entries to the Debug
mode of operation by asserting the HOST_BRK signal. The ADS user interface program
on the host computer periodically polls the HOST_BRK signal from the keyboard polling
routine. If the HOST_BRK signal is asserted, the host computer will determine which
command converter is requesting service by reading the ADM_INT signal. The
INT_ACK signal is asserted by the host computer when a service request has been
recognized. Further details on the functions of each signal will be given in a subsequent
section. Figure 3-2 illustrates the 37-pin cable and the direction of the signal groups.
3.1.2 Host Computer Interface Cable
The host computer interface card interacts with the command converters via a 37-pin
ribbon cable assembly. Each end of the ribbon cable has a 37-pin subminiature-D
Insertion Displacement receptacle connector. The cable assembly is approximately 4 feet
in length and is designed so that additional command converters may be easily attached to
the existing cable by crimping on new connectors.
Normally the ADS is shipped with an application development module (ADM), and
power for the command converter is supplied by the host computer interface card via the
37-pin cable. Power for the ADM card is provided by a wall power transformer. The
ribbon cable is not designed to draw more than 2 amps current at 5 volts. Since each
command converter draws approximately 250 milliamperes, it is safe to power all eight
units via the cable, but the target systems must be powered by a different source to ensure
correct operation.

3.1.3 Command Converter Card
The command converter is based on a DSP56002, which uses its on-chip resources to
minimize and simplify the interface to the target JTAG/OnCE debug port. Communication
with the host computer is via the DSP56002 Port B, while the serial interface to the target
DSP is via the DSP56002’s SSI port.
Each command converter has a unique address, ranging from 0 to 7. This allows the user
to debug multiprocessor systems where as many as eight command converters are
physically in the target system. JG2 of the command converter card defines the address
selected for that card.

3.1.4 Command Converter Handshake Signals
The DSP56002 on the command converter card is configured in such a way that bits 0–7
of its Port B are used for 8-bit data transfers, and bits 8–14 are used for data transfer
control.
There are three output control bits in the middle order byte of the DSP56002 Port B data
word. These bits are the ADM_INT, ADM_REQ, and ADM_ACK signals. ADM_REQ
and ADM_ACK, act as handshake lines for reading and writing data. ADM_INT acts as a
flag to indicate whether the ADM is requesting host computer service. These three control
bits are part of the host parallel control bus. They are enabled when the host computer
selects the ADM.

Host Computer Hardware
There are three input control bits in the middle-order byte of Port B data word that
represent the HOST_ACK, HOST_REQ, and INT_ACK. These signals are sent from the
host computer for reading and writing data. INT_ACK informs the monitor program that
the host computer has received its service request and is ready to communicate.
HOST_BRK is a wired-OR control line. HOST_BRK is used by the command converter
to inform the host computer whenever the target DSP has entered the Debug mode of
operation for non-JTAG devices only. Since more than one command converter may be
started for a user debug session, more than one may hold HOST_BRK active low at one
time. Once this signal is asserted it may only be deasserted by the host computer or by a
command converter reset.
3.1.5 Command Converter Interface Connector
The target application board must have a 14-pin connector to interface to the command
converter controller. This interface comprises nine signals and three ground connections
on a 7-row × 2-column male pin header, which are spaced on 1/10 inch centers as
illustrated in Figure 3-4 on page 3-7.
Since the target system will have a resident reset circuit, it is recommended to have an
AND gate in series with the CC_RESET signal. This will insure that the target DSP will
be reset with a valid VOL level from either the target reset circuit or from the command
converter. The pull-down resistors are to insure that no false signals are propagated to the
JTAG/OnCE circuit when the test data input/debug serial input (TDI/DSI) and test data
clock/debug serial clock (TCK/DSCK) lines are active. The test data out/debug serial
output (TDO/DSO) pullup is to insure that the Debug Acknowledge signal from the OnCE
circuit is deasserted. The debug request (DR) pullup is to insure that the command
converter controls when the target DSP is placed into its Debug mode.

3.1.7 TCK Drive and Timing Considerations
The signals from the command converter are TDO, TCK and TMS, and TRST. Signal
TCK requires fast rise and fall times dictated by the TCK pin timing specification, and
consequently attention must be given to the drive capabilities of the circuits driving this
signals. There is no problem with TDO, as each TDO output is connected to only one TDI
input. TMS need only be valid at the rising edge of TCK, similarly there is no problem
with TRST as the reset signal is not subject to the timing constraints of TCK.
There is a potential problem with driving the TCK circuit with a large number of target
devices. The problem is related to the rise and fall times of TCK, caused by excessive
capacitance, which can cause communication problems with a single circuit connecting
multiple TCK input pins.
Acceptable transition times may be achieved for TCK by driving no more than four JTAG
inputs from each buffered output. This may be achieved with two configurations.
Figure 3-6 shows one method. Here (in effect) one signalling connects each of the TCK
inputs. A buffer is placed in the circuit after each fourth input, at most, to restore the signal
quality for subsequent inputs. The propagation delay of the buffer is not significant.
Figure 3-7 shows another possible configuration which also enables signal quality to meet
the requirements. In this configuration the signal is split and buffered into a number of
parallel TCKn signals. Each of these signals may drive up to 4 TCK inputs.

Either configuration above is equally valid. The choice will depend on practical
considerations related to each project, or a combination could be used.
JTAG signal TMS may also need some consideration. Although TMS is not subject to the
strict requirements as TCK, it is still important that TMS has settled to a valid level at the
rising edge of TCK.
3.1.8 Resetting Target DSP Devices.
The RESET signal and TRST signals from the command converter are typically connected
to all target devices on a JTAG chain. RESET and TRST are asserted by the ADS
command FORCE R. All devices on the JTAG chain handling the specified command
converter device are reset. Execution control is established immediately after deassertion
of TRST before any instructions are executed. The sequence of events is illustrated in
Figure 3-8. Because all targets on the JTAG chain are connected to the same RESET
signal, all devices enter reset. The JTAG controller is still active after deassertion of TRST
during reset, and while RESET is held low, the JTAG instruction DEBUG_REQ is
clocked in. When RESET is deasserted, the device is immediately in Debug mode, with no
instructions executed since releasing RESET.
