摘要

为了实现面阵CCD传感器采集的数据在TFT液晶屏上的快速显示，提出一种基于现场可编程逻辑门阵列（FPGA）的快速显示系统。利用FPGA构建软核处理器（NiosII），采用专用IC模块AD9929作为CCD驱动与处理芯片，并依据TFT液晶屏和芯片AD9929的接口时序设计驱动电路，利用DMA技术实现采集数据的快速显示。电路的测试结果表明，利用该方法可以把面阵CCD传感器采集的数据快速显示在TFT液晶屏上，在工业现场监视场合具有广泛的实用性。

Abstract

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 widely applications in the industrial field surveillance.
