| 摘 要： | 结合DSP硬件结构,首先对指数哥伦布码算法的实现进行结构上的调整,其次对熵解码部分的手工汇编实现高效的流水编排,最后结合熵解码数据的存储访问对cache进行优化。仿真结果与传统的C语言相比,程序运行周期降低了约21.49%,码率也显著提高。

| Abstract: | In this paper, combining DSP hardware architecture, the implementation of Exp-Golomb code algorithm is first adjusted structurally; Then highly efficient pipeline arrangement is achieved on the hand assembly of entropy decoding part; Finally the cache is optimized combining the storage and access of entropy decoding data . The results demonstrate that the program operation cycle reduces by about 21.49% compared with traditional C code, and the code rate also improves significantly. |
