摘要
VGA(视频图形阵列)作为一种标准的显示接口得到广泛应用。依据VGA显示原理,利用VHDL作为逻辑描述手段,设计了一种基于现场可编程器件FPGA的VGA接口控制器。在使用FPGA的嵌入式系统中能代替VGA的专用显示芯片,节约硬件成本,节省计算机处理时间,加快数据处理速度并具有显示面积大、色彩丰富、承载信息量大、接口简单等优点。
VGA(video graphic array)been widely used as a standard interface.According to the principle of VGA display,use of the VHDL as a means of logical description,this design based on field programmable device FPGA VGA interface controller.Using FPGA instead of the VGA special graphics chips in embedded,Can saving on hardware costs,save computer processing.Accelerate the speed of data process ing and has the advantage of display area,rich colors,carrying information,and simple interface.
