基于FPGA的VGA图像显示系统的设计与实现

摘要

According to the principle of VGA interface design,a VAC image display control system based on DE2 -70 was proposed. To compare with the traditional VGA control system,the small size of (he FPGA, recontigurable,so it is suitable for small portable system equipment design. The Quartus II 9. 1 simulation results was presented. It achieved a Chinese character display and the VGA display of color bar signal on the hardware platform. The experimental results show that the FPGA as a processor to control the VGA image and character display.it can achieve the desired results,(he control system can overcame the drawbacks of the traditional VGA.%文中依据VGA接口的设计原理,提出一种基于DE2 - 70的VGA图像显示控制系统,与传统的VGA控制系统相比,由于FPGA体积小,可重构,因此很适合小型便携式系统设备的设计,给出了Quartus Ⅱ9.1的仿真结果.在硬件平台上实现了VGA的汉字显示和彩条信号的显示.实验结果表明:由FPGA作为处理器来控制VGA图像的和汉字的显示,能够达到预期的效果,克服传统VGA控制系统的弊端.
