基于FPGA的VGA接口技术

本文设计了一种基于现场可编程逻辑器件FPGA计的多显示模式VGA接口。通过设计一种全新的分频算法,使该接口能支持从VGA到SVGA多达13种显示模式,在实际利用FPGA的嵌入式系统中能替代VGA专用显示芯片,节省了计算机处理过程,加快了数据处理速度,节约了硬件成本。

The VGA Interface Technology Based on FPGA

The design of a field programmable logic devices based on the FPGA of multi-mode VGA display interface. Through the design of a new sub-frequency algorithm, so that the interface can support from VGA up to 13 SVGA display mode, in the actual use of embedded systems in FPGA can substitute for VGA display chips, saving the computer process, Speed up the data-processing speed, saving the cost of hardware.
