摘要
为了更好地满足嵌入式系统的实时性要求,对原有的MPEG-4视频解码算法进行了一系列的改进.根据ARM微处理器的体系结构,优化MPEG-4视频解码算法和代码,并进行软件仿真.实验数据表明,优化后的解码器性能得到了全面提升。结合ARM的S3C4510B开发平台,对MPEG-4视频解码程序进行移植和调试,成功地实现了嵌入式系统的MPEG-4视频实时解码.
In order to satisfy the real-time requests of embedded system, the original MPEG-4 video decoding algorithm is improved. The decoding program is optimized in the aspects of algorithm and codes according to ARM architecture, the simulation has been clone as well. The experiment data demonstrats that the decoder performance is promoted obviously. MPEG-4 video decoding program is transplanted and debugged by S3C4510B platform, the embedded MPEG-4 video decoder is accomplished successfully.
