摘　　要：本文详细阐述了TMS320DM6446的硬件平台及软件架构,该平台以H.264的参考代码x264为实验平台,针对其实际的应用,采用相应的方法,在保证性能的前提下,对原始代码作了与平台无关的裁剪,着重介绍了编码的移植过程以及编码的系统级和汇编级优化,给出了相应的优化结果。This article elaborates TMS320DM6446 hardware platform and software architecture. The platforms is based on x264 code, and uses the appropriate methods to cut the original code with platform--independent under ensuring performance for its practical application. It focuses on the transplantation coding encoding process, system--level optimization and compilation of class, and gives the results of the corresponding optimization.
