摘要

利用现场可编程逻辑器件FPGA产生VGA时序信号和彩条图像信号,并将其作为信号源,应用于彩色等离子显示器的电路开发,方便彩色等离子显示器驱动控制电路的调试。FPGA芯片具有可靠性高、编程灵活、体积小等优点，实验经 过 软硬件调试，最终在显示器上显示彩条正确图像。利用此原理，可以设计更多的彩色图像，且可将采集的图像进行实时显示，将此作为信号源，应用于显示器电路的开发或某些嵌入式系统中，进行视频设备的调试与性能分析或系统中信号处理模块的调试与性能分析等。

Abstract

VGA-timing signals and color strip image were obtained by using FPGA.The signals were used as sources when developing the circuits of color plasma display panel, and it took great convenience to the debugging of the driving and controlling circuit of color plasma display panel.The FPGA chip has the advantages of high reliability, small volume, flexible programming,just because of this,the test could achieve the desired results,display scree displays color bar signals.According to this principle, we can design color image more, and make the image real-time display, such as the signal source, used in display circuit development or some embedded systems, video equipment debugging and performance analysis of the system signal processing module debugging and performance analysis.

Keywords:FPGA, VGA interface,timing control, color bar signals
