Optimization and realization of MPEG-4 video decoder based on S3C4510B

Mei-hua Gu

Abstract

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 done 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.
