Optimization of Video Decoder System Based on TMS320DM642

XU Xiao-dong

Abstract

TMS320DM642 is a newly digital media processor of Texas Instruments.The digital signal processor (DSP) is described and a multichannel real-time MPEG-4 video decoder system based on the DSP is realized. And the system level optimization strategies and code level optimization techniques are discussed. Experiment shows that great performance is reached by optimization techniques and strategies.
