摘要
介绍了TMS320C6416型号DSP内部协处理译码器VCP的算法和结构。其基本思想是CPU通过寄存器控制VCP,并由EDMA控制器同VCP进行数据交互来实现译码。文中还使用VCP对802.16e标准中的几种卷积码进行维特比译码,并分析了性能。
This paper introduced the structure and arithmetic of Viterbi coprocessor embedded in Texas Instruments＇ TMS320C6000 family DSP device. The basic idea is that CPU accesses VCP through registers, while exchanging data between VCP and EDMA controller to realize decoding. In addition, the several Viterbi decoded data according to the convolutional code in protocol 802.16e using VCP are gotten, and their performances are analyzed.
