S3CC11B/FC11B CaImMAC1616 PROGRAMMING MODEL In this chapter, the important features of each unit in CalmMAC16 are discussed in details. How the data memories are organized is discussed and data memory addressing modes are explained. The major components of the CalmMAC16 are: • Multiplier Accumulator Unit (MAU) Multiplier – Input Registers – Output Register Multiplier Accumulators Saturation Logic X0, X1, Y0, Y1 P MA0, MA1 Multiplier Accumulator Shifter 36-bit Arithmetic Unit Status Register • MSR1 Arithmetic Unit (ARU) Accumulator Saturation Logic A, B, C, D Accumulator Shifter 16-bit Arithmetic Unit Status Registers • MSR0, MSR2 Barrel shifter & Exponent detection Unit (BEU) 16-bit Exponent Detector 16-bit Barrel Shifter – Input Registers – Output Registers • SA, SI SG, SR RAM Pointer Unit (RPU) 2 Modulo Address Generator Bit-Reverse Generator Indirect Address Pointers RP0, RP1, RP2, RP3 Index Registers SD0, SD1, SD2, SD3 Extended Index Registers SD0E, SD3E Direct Pointers RPD0, RPD1 Modulo Configuration Registers MC0, MC1 Alternative Bank Pointers RP0, RP1, RP2, RP3 Alternative Bank Index Registers Alternative Bank Extended Index Registers SD0, SD1, SD2, SD3 SD0E, SD3E 21-3
