Design of VGA display controller based on FPGA and VHDL

The paper designs a VGA image and writing display controller with FPGA chip based on EDA technology. The system designs VGA display control module with VHDL, produces the image signal and the control signal with FPGAo In the process of designing the system deposited the color image and the writing information through the LPM module transfer, finally completes video data processing through the simulation and downloading only based on the single chip. This design has achieved a request in the area and speed easily.
