基于ARM的MPEG4视频解码器的优化。本文对嵌入式软件开发人员有参考价值，本人从事嵌入式多媒体软件开发。对MPEG4，ARM，MIPS有些研究，此文对基于ARM的MPEG4视频解码器优化为开发人员提供了新的思路。-ARM-based MPEG4 video decoder optimization. In this paper, embedded software developers have a reference value, I engaged in embedded multimedia software development. On MPEG4, ARM, MIPS, some research, this article based on ARM s MPEG4 video decoder optimized for the developers to provide a new way of thinking.
