基于FPGA的VGA图像控制器的设计与实现

The Design and Implementation of VGA image Controller Based on FPGA

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Verilog HDL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。与传统设计相比,增加了光标处理器,便于与嵌入式系统扩展。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,节省计算机处理过程,加快数据处理速度。

As a standard display interface,VGA has been widely used. According to the principle of VGA display, completed interface controller of VGA was based on FPGA while using Verilog HDL as a means of logic description. Compared to the tradition design, add the cursor processor is convenient to expand in the embedded systems.
