基于FPGA的VGA图像显示系统的设计

摘要

As a standard display interface,VGA(video graphics array)has been widely used. According to the principles of VGA and FPGA(field programmable gate array),the designed VGA interface based on FPGA can send the data to the dis-play directly,and grayscale of the output image was added to this design. Compared to the traditional design,there is no com-puter processing procedure in the design,which can save the expense of hardware and enhance the speed of data processing. It is widely used to the domain of video display.%VGA(视频图形阵列)是一种标准的显示接口,被广泛应用.根据VGA,FPGA(现场可编程门阵列)的作用原理,设计的基于FPGA的VGA接口可以直接将数据送至显示器,同时增添了关于输出图像灰度等级的设计.与传统设计相比,该设计没有计算机的处理过程,可节省硬件成本,加快数据处理速度,被广泛应用到视频显示领域.
