An efficient architecture design for VGA monitor controller

In this paper, we present the design and implementation of an efficient hardware architecture for VGA monitor controllers based on FPGA technology. The design is compatible with PLB bus and has a high potential to be used in Xilinx FPGA-based systems. The ability to provide multiple display resolutions (up to WXGA 1280×800) and a customizable internal FIFO make the proposed architecture suitable for several FPGA devices. Furthermore, we have also offered a useful software library to enable the text mode feature. These highlight features have been validated through the demonstration of an application.
