Abstract: As a standard display interface, VGA(Video Graphics Array)has been widely used. This paper presents the design and implementation of VGA controller. Hardware architecture is implemented on a ALTERA CYCLONE-ii EP2C5T144C8FPGA（Field Programmable Gate Array）chip. The paper has given its top layer module design and the timing function simulation. Detailed information is focused on the system architecture, hardware design and software programming. This controller is developed using only VHDL (hardware description language) based in the IEEE standards, to ensure the portability with any manufacturer. The system can display various color strip, Chinese characters and image. The results show that this proposed algorithm gives good performance with short processing time, low resource utilization, small power consumption and memory usage. Because the data can be sent directly to monitors, the design can speed up data processing, improve system reliability in real time and save hardware resource.
