| 摘 要： | 针对采用视频D/A处理器将LCD转VGA时出现的带宽不够,VGA显示器屏闪的问题,给出了一种采用FPGA结合视频D/A的显示控制器实现方法.该方法将处理器送出来的LCD视频数据放在SRAM中缓存,再按VGA的规格要求将数据读出并送至D/A转换成VGA格式的视频输出,整个处理流程由FPGA来控制,有效地解决了显示输出占用...

| Abstract: | Aiming to solve the problem that the bandwidth is not enough and the VGA monitor is unstable when using video D/A to convert LCD to VGA,the paper presents an implement method of controller that uses FPGA to cooperate with video D/A processor.This method stores the LCD video data that comes from MCU into SRAM for buffering,then read it regularly as the VGA rules need and send to D/A,which converts LCD to VGA,the whole process is controlled by FPGA,and it effectively solves the problem that video output occup... |
