TMS320C54x DSP Processor

TMS320C54x DSP Processor

• The TMS320C54xE DSP is a fixed-point digital signal processor (DSP)
• it can use either of two forms of the instruction set:
  

1. a mnemonic form
   
2. an algebraic form.

FEATURES

• it uses harvard architecture
• one program 3 data memory spaces with separate buses
• simultaneous accesses to a program instruction and two data operands and writing result at the same time
• on chip ROM,dual RAM,single access RAM.
• Transfers between the memory spaces are also possible.
• a powerful instruction set with hard ware supported.
• single instruction repeat and block repeat operations,block memory move instructions.
• Arithmetic instructions with parallel and store.
• It has on chip peripherals like clock generator. hard ware timer,wait state generator,parallel I/O ports,serial I/O ports...

BUS STRUCTURE

• four pairs of 16-bit buses (PAB,PB,CAB,CB,DAB,DB,EAB,EB)
  
• each pair consists of an address bus and data bus
• One program bus pair-PAB,PB
• 3 Data bus pairs-CAB,CB,DAB,DB,EAB,EB.

CPU

• 40 bit ALU
• two 40-bit accumulators
  
• a barrel shifter
• a 17 x 17 bit multiplier
  
• a 40-bit adder
• a cssu(compare,select and store unit) unit
• an exponent encoder
  
• DAGEN
• PAGEN
• a MAC UNIT
