Abstract:

With the development of the multimedia and network technology,video applications such as VOD,video-phone etc.are used more and more widely in our life.We implement and optimize the MPEG-4 decoder based on TMS320 c6416 DSP for its high performance and easy implementation.Based on the architecture and instruction characteristic of the DSP,structure-level,program-level,code-level optimization was conducted respectively.Experimental data show that the decoder implemented can decode video in real time efficiently.

Key words: video decoder, DSP, MPEG-4, optimization implementation
