Design of VGA Controller using VHDL for LCD Display using FPGA

Abstract

Basically, here I have used VGA for implementing basic characters/Symbols that can be either used in advertisements that deals with real-time application. So, I thought of using VGA as a standard for this implementation as it is the basic graphics array and compatible with other graphical arrays. This project also describes about the design of VGA (Video Graphic Array) Controller using combination of three bit input data to control eight differences colors to display text at monitor by using on board pushbuttons for the input. Three color signal referred to collectively as R (red), G (green) and B (blue) signal(i.e. RGB). The VGA monitor using resolution of 640 by 480 by mode to display Characters/Text/Images in different colors. Here, we used VHDL language on Xilinx ISE software for interfacing the required peripheral to the Xilinx FPGA Spartan Series. Where, I implementing the application of VGA with the help of VHDL language on Xilinx FPGA, that will contain the logic part. For Simulation part we are using Modelsim 10.2. Finally, the results that we obtained for VGA application implementation.
