介绍了TMS320C64X系列DSP内部Turbo码协处理器（TCP）的结构和算法。给出了使用TCP实现符合3GPP协议的Turbo译码的程序流程，实现了一种使用中断服务程序控制的高校处理流程，最后给出了TCP译码性能与处理时延的硬件实现结果，并做出了一定的分析-TMS320C64x series DSP introduce the Turbo code internal coprocessor (TCP) structures and algorithms. Realize the use of TCP is given in line with the 3GPP agreement Turbo decoding process flow to achieve a break in service use of colleges and universities deal with flow control, and finally gives the TCP decoding performance and hardware implementation of the deal with time-delay results, and to do a certain amount of analysis
