Video compression is complex and it is difficult to realize a real-time video encoder on embedded systems.To solve this problem
Optimization methods of MPEG-2 video compression algorithm based on TMS320C6416 DSP platform are given in this paper.These optimization methods include design of double buffering based on EDMA
rewriting of C codes using linear assembly and improvement on quantization.Test results show a significant increase on video compression speed after optimization and D1 video sequences can be encoded at a speed of about 43 frames per second in real time.
