摘　　要：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QuartusⅡ9.1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。According to the principle of VGA interface design,a VAG image display control system based on DE2-70 was proposed.To compare with the traditional VGA control system,the small size of the FPGA,reconfigurable,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,the control system can overcome the drawbacks of the traditional VGA.
