Design of Driving Circuit for Area Array CCD Based on FPGA

In order to realize the speediness display collected by the area array CCD,a fast display system based on field-programmable gate array(FPGA) is presented.Using FPGA to build-up soft core processor and using appropriative IC module AD9929 as the driver processing chip of CCD,and then it designs the driver circuit according to the interface time order of TFT liquid crystal screen and chip AD9929.Finally,the speediness display of collected data can be realized through DMA technique.The testing results of circuit show that this method can make the collected data by area CCD rapidly display on the TFT liquid crystal screen,which has wide applications in the industrial field surveillance.
