Implementation of H.264 Realtime Video Codec Based on DM642 Platform

The paper briefly introduces the features of Video/Imaging Fixed-Point Digital Signal Processor TMS320DM642 and the hardware structure of H.264 codec,and analyzes the software task flowchart and principle.Then the implementation and optimization of Video codec on TMS320DM642 is mainly discussed.Experiment results show that the realtine processing of CIF images can be realized while the high image quality and compression efficiency are preserved.
