摘　　要：本文在利用通用DSP TMS320C64x实现HDTV视频解码过程中,通过软件仿真,使用C/C++编译器参数优化设置和人工流水线汇编优化等手段,对IDCT和运动补偿关键模块进行优化,解决了在两级Cache结构下数据的存储问题,取得了显著成效。In the process of HDTV video decoding based on TMS320C64x, this paper present a way of software simulation to optimize the key module of IDCT and motion compensation. In the simulation, we use the C/C++ compiler's optimized configuration parameters and software pipeline. We also solve the problem about how to make use of two-level cache. The result make great progress.
