基于TMS320DM648的H.264视频压缩系统

Abstract

Abstract:

In this paper,an H.264 video compression system based on TMS320DM648 is designed.In the video compression system,motion estimation improves image quality with increasing of computational complexity.To solve this problem,the algorithm is improved by incorporating a new motion determination criteria and an adaptive search strategy.Furthermore,program optimization is performed according to the characteristics of TMS320DM648.The simulation results show that the new video compression system can satisfy the requirements of high image quality and real-time performance,and can be applied in media processing.

Key words: H.264;TMS320DM648;motion estimation;program optimization
