简短描述：16-bit Fixed-Point Digital Signal Processor Core
详细描述：
The C32025TX is a single-chip, high performance 16-bit fixed-point digital signal processor core. It implements the same instruction set as the TMS320C25 and provides the same interrupts, serial interface and timer, executing most of instructions in a single clock cycle.
The C32025TX is a microcode-free design developed for reuse in ASIC and FPGA implementations. The design is strictly synchronous with both-edge clocking, a synchronous reset, and no internal tri-states.
