A image processing system based on high performance fixed-point Digital Signal Processor (DSP) TMS320C6201 is discussed. This system includes drive circuit module , A/ D and D/ A transform module , digital signal processing module and video frequency display module. As a result of using high performance and low dissipation processing chip , the system owns the virtues of high real-time , performance stability , high precision , small bulk and low dissipation , and has wide application in the future.
