基于TMS320DM6446的X264编码器的移植和优化OA北大核心CSTPCD
Migration and Optimization of X264 Encoder on TMS320DM6446
比较了H264的几种开源代码的优缺点,选择X264算法.由于X264算法需要经过向DSP上的移植和优化才能满足实时处理的要求,选用TMS320DM6446作为硬件平台,完成了X264编码器向TMS320DM6446的移植和优化,优化主要包括编码器选项、运动估计算法、EDMA以及内联函数等方面的优化.实验结果表明,在保证视频质量的前提下,编码效率明显提高,基本达到CIF格式序列的实时编码要求.
Compared with the advantages and disadvantages of several open source codes of H264,X264 algorithm is selected. Because that X264 algorithm needs to be migrated and optimized to the DSP in order to meet the requirements of real-time processing and choose TMS320DM6446 as the hardware platform, X264 encoder is migratec and optimized to TMS320DM6446. Optimization mainly includes encoder options, motion estimation algorithm, EDM.A and inline function optimizatio…查看全部>>
