TMS320VC5402 Datasheet

Digital Signal Processors & Controllers - DSP, DSC


The TMS320VC5402 fixed-point, digital signal processor (DSP) (hereafter referred to as the 5402 unless otherwise specified) is based on an advanced modified Harvard architecture that has one program memory bus and three data memory buses. This processor provides an arithmetic logic unit (ALU) with a high degree of parallelism, application-specific hardware logic, on-chip memory, and additional on-chip peripherals. The basis of the operational flexibility and speed of this DSP is a highly specialized instruction set. TMS320VC5402 Features • Advanced Multibus Architecture With Three Separate 16-Bit Data Memory Buses and One Program Memory Bus• 40-Bit Arithmetic Logic Unit (ALU), Including a 40-Bit Barrel Shifter and Two Independent 40-Bit Accumulators• 17- × 17-Bit Parallel Multiplier Coupled to a 40-Bit Dedicated Adder for Non-Pipelined Single-Cycle Multiply/Accumulate (MAC) Operation• Compare, Select, and Store Unit (CSSU) for the Add/Compare Selection of the Viterbi Operator• Exponent Encoder to Compute an Exponent Value of a 40-Bit Accumulator Value in a Single Cycle• Two Address Generators With Eight Auxiliary Registers and Two Auxiliary Register Arithmetic Units (ARAUs)• Data Bus With a Bus-Holder Feature• Extended Addressing Mode for 1M × 16-Bit Maximum Addressable External Program Space• 4K x 16-Bit On-Chip ROM• 16K x 16-Bit Dual-Access On-Chip RAM• Single-Instruction-Repeat and Block-Repeat Operations for Program Code• Block-Memory-Move Instructions for Efficient Program and Data Management• Instructions With a 32-Bit Long Word Operand• Instructions With Two- or Three-Operand Reads
