C32025TX - TMS320C25-compatible Digital Signal Processor

32025 DSP.PNG

The C32025TX is a single-chip, high performance 16-bit fixed-point digital signal processor. It is derived from the TMS320C25 design by Texas Instruments®.

C32025TX implements the same instruction set as the TMS320C25 and provides the same interrupts, serial interface, while executing most of instructions in a single clock cycle, some of them four times faster. The core implements a Harvard-type architecture and has a 16-bit reload timer and a synchronous serial port for a direct codec interface.

Highlights

  • Compatible with Texas Instruments® TMS320C25 DSP
  • Up to 4 times faster than the original chip in terms of clock cycles per instruction
  • Control Unit with 16-bit instruction decoding and repeat instructions function
  • Central ALU with a 16-bit parallel shifter to perform 32-bit arithmetic and logical operations
  • 16-bit Auxiliary Register Arithmetic Unit with eight 16-bit registers
  • 3 memory addressing modes available - direct, indirect and immediate
  • 8-level Hardware Stack

Benefits

  • Architecture of the C32025TX ensures smooth integration in the user application
  • A Harvard-type architecture maximizes processing power by maintaining two program and data buses for full speed execution
  • The C32025TX implements the same instruction set as TMS320C25, but some instructions may be performed four times faster
  • Most instructions can be used in repeat mode for efficient use of program space
  • Three different instructions can be active during any given cycle

The C32025TX can be downward configured and its performance will be lowered so it becomes the C32025 – a 16-bit fixed-point digital signal processor core, pin and timing compatible with the TMS320C25 DSP from Texas Instruments.

The C32025 has the same instruction set as the TMS320C25 and also provides the same interrupts, serial interface and timer.
