technology has been more and mole important in highspeed and realtime is widely used in graph and image processing, voice identification,intelligent checking,industry control and other lot of reatimedata acquisition and processing systems choose DSP(Difital Signal Processor)as hiscore processor,which ask for dealing with the collecting image data this paper,we proposed a highspeed data collection system based on the digital signal solved a lor of
