Optimization of H.264 Video Encoder Based on DM642

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.
