摘要
介绍了H.264视频解码原理,分析了基于Blackfin533的H.264解码的硬件平台和软件设计流程,重点讨论了C代码优化和汇编优化,最后对去方块滤波算法进行了具体优化,可缩短近10%的解码时间。
The principle of H.264 video decoding, hardware platform and software design of H.264 video decoder based on Blackfin533 are introduced, and C code optimization and assembler optimization are discussed. Finally, an optimal filtering algorithm is analyzed, and this algorithm can reduce about 10% of the decoding time.
