一种基于权电阻网络的VGA显示方案设计

本文提出一种基于FPGA技术的权电阻VGA显示方法,该方法不仅以低成本实现了通用VGA接口功能,而且外扩了嵌入式仪器仪表设备芯片级常用总线,只需仪表微处理器单元具有通用的SPI、UART等总线接口方式,即可实现VGA高速图像显示。实验结果表明,该方法通用性强,显示色彩真实,而且可以在不使用VGA显示卡和计算机的情况下实现高速图像的显示。

A Novel VGA Display Design Based on Weighted Resistance Network

The right of resistance VGA display method based on FPGA technology is proposed by the paper. This method not only re- duces the cost to realize the general VGA interface function, and expands outside chip-level common bus of embedded instrumentation e- quipment. It has the instrument microprocessor unit with the common SPI and UART bus interface mode, and then it can achieve the high-speed image display of the VGA. The experimental results show that this method is universal and can display true color, and the design need not use VGA graphics card and computer to realize high speed image display.
