【摘要】 分析了H.264软件解码器的结构,指出了影响速度的瓶颈,并给出了一种优化方案—从程序结构入手,结合MMXTM技术,对H.264软件解码器进行全面的优化。优化后的解码器在P3/800MHz以上的PC机上能够对于CIF格式的H.264序列进行实时解码。更多还原

【Abstract】 The architecture of H.264 software decoder is analyzed, the bottleneck affecting the speed is pointed out, and an optimization scheme is given. Starting from program structure and in combination with MMXTM technology, the H.264 software decoder is fully optimized. The optimized decoder can perform real-time decoding of H.264 sequences in CIF format PC’s above P3/800 MHz.更多还原
