VGA display is Video Graphics Array and it comes in an account in 1987. It displays approximately 256 simultaneous colors. Also, it has 640 X 480=307,200 pixels maximum resolution. But with this resolution graphic card able to generate only 16 colors. This design is used to eliminate the use of CPU to display the textual data. The design will be developed using the programmable logic device- based logic analyzer. And also it is used to combine a video display controller with an SRAM memory controller. And this design used to create a Video frame buffer.
The SRAM should be 256Kx16 CMOS static ram memories. And these memories are used to store images that will be displayed on the VGA screen Now data from the logic analyzer designed by others is combined with this design. The final goal is by using single-chip CPLD and SRAM based logic analyzers which display the output measurement to monitor without interfaced with CPU. CPLD includes the generation of VGA timing signal, finite state machine, and logic control.
