摘要:

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。

关键词: FPGA VGA 分频算法

Abstract:

A multi-view-mode VGA in teHace core is designed in this paper, which is based on FPGA. This interface can supply 13 view modes from VGA to SVGA with  a new divide-frequency algorithm, and it can replace the VGA application chip in actual FPGA embeded systems, which saves time in the computing process, accelerates the speed of data processing, and saves the cost of hardware.

Key words: (FPGA, VGA, divide-frequency algorithm)
