摘要
本文分析了MMX的技术特点及其编程要点 ,利用MMX指令集 ,并结合小波变换 ,实现了基于H .2 6 3+的低码率视频小波编码算法。实验表明 :经过MMX优化的视频小波编码能够充分利用MMX的强大功能 ,取得良好的主、客观视觉效果。
This paper analysis the feathers of MMX and its programming essentials. Using MMX instruction sets, we realize video codec algorithm under very low bit rates environment combining with wavelet transform. Experiments show that the optimized wavelet-based video codec can make the best use of MMX′s functions. The superior performance of the proposed scheme is demonstrated with experimental results.
