摘要
基于Log_MAP算法,提出了一种TURBO码DSP实现方案。利用内联函数、循环展开,软件流水线技术对算法进行了优化,在TMS320C6416芯片上实现了36Mbps的编码速率及1.6Mbps译码速率(5次迭代)。该方案可以灵活设置码率、帧长、迭代次数等关键参数,适用于不同要求的高速通信系统。
This paper presented a DSP implementation scheme of turbo codes based on the Log_MAP algorithm. By using some technologies like intrinsics,loop unrolling and software pipeline to optimize the algorithm,our scheme was implemented on TMS320C6416 with the encoding speed of 36Mbps and the decoding speed of 1.6Mbps. This scheme can flexibly specify the data rate,frame length and iterative number and thus meets the demands of different high speed communication systems.
