摘　　要：论述了基于FPGA(Field Programmable Gate Array)的实时图像处理系统中VGA(Video Graphics Array)显示控制模块的设计方法。对存储在SRAM中的ITU-656格式的图像数据进行D/A(Digital to Analog)转换,用VHDL编写了对THS8134的控制信号和VGA显示的水平、垂直同步信号。该设计在整个系统中进行了联调,经验证,能正确实时地显示图像。A VGA control module for real-time image processing system was designed based on FPGA. The realtime digital image data in ITU-656 format was converted into analog data The control signal were synthesized according to the VGA principle and scheduling of THS8134, and the horizontal and vertical synchronization signals were synthesized according to the VGA interface standard using VHDL. The desiigned VGA module was tested with the system. It has been shown that the VGA module can operate properly.
