硕士毕业论文《MPEG4-ASP视频编码器算法设计

及DSP实现》：研究和实现了MPEG4-ASP视频编码标准的关键算法——运动估计和全局运动估计，掌握了视频压缩编码的核心技术以及在通用DSP平台上实现视频编码器的技术要点并实现了编码器的原型，为MPEG4-ASP编码在嵌入式领域的实际应用和开发奠定了基础。

-In chapter one and two, we mainly introduce the basic principle of video compression and the video compression standard up to now. In chapter three, we introduce the profile/level in the mpeg4 standard and focus on the discussion of new charcters. In chapter four, we make a detai research and improvement on the key arithmetic module in MPEG4—Motion Mstimation and Globle Motion Estimation, and adopt improved PMVFAST method and a motion vector based no-iterative global motion estimation method in the codec. The experiment proves that the choosed methods are much more efficient than traditional ones. In chapter five, we discuss the DSP implementation of MPEG4-ASP video codec. Considering the hardware platform, we do the software structure design, data movement and memory, cache arrangement. We also do the software pipeline and assmble language optimization. The encoder now can get the achievement of encoding the CIF format fr a mes 20fps. In the last part of　the paper, we make a short conc
