摘　　要：在视频压缩系统中,电源模块设计非常关键,它直接影响着压缩系统的最后实现和稳定运行。本文针对以DSP处理芯片MAP-CA为核心的视频压缩系统为例。介绍一种可行的电源模块设计方案,在稳定供电基础上,使MAP-CA核心电压优先于I/O电压的供电顺序,保证合理的供电顺序。通过电压监控电路,保证系统安全稳定的运行。The design of power supply module is very pivotal, because it influences the system realizing and running in the video frequency compress system. The paper introduces a viable design project of supply power , as MAP - CA. It can make the core pressure of MAP - CA taking precedence of I/O. Then it can assure logical gradation of supply power. It can assure the system running safely and stably by the supervising circuit of pressure, too.
