摘要
分析了T264编解码的结构和复杂度.结合DM642硬件特点对相关算法进行了选择、裁减和优化,给出了粗化搜索的算法.在DM642 EVM上实现了硬件仿真,并重点进行了优化工作,包括使用编译器选项、C代码改写、写线性汇编、数据搬移优化等有效的综合策略.这些优化方法有效提高了存储器的访问效率和代码的并行性.设计实现了DM642平台的T264算法深度移植.
The thesis analyzes the codec structure and complexity of T264 and gives the coarse search algorithm combining with the hardware characteristics of DM642.In the DM642 EVM Emulation has been realized,and the focus is optimized,which includes the use of compiler options,C code rewriting,writing a linear compilation,data move optimization.The above optimizations help pwomote the effeciency and overall.optimization strategies of memory access and code parallelism.The design achieves the optimization and the depth migration of T264 algorithm on the DM642 platform.
