基于FPGA的大尺寸LED文字显示屏的一种实现方案

A scheme of FPGA based large size LEDdisplay for characters

介绍一种使用三万门规模的FPGA和单片机相结合的方法来实现大尺寸LED文字显示屏控制器的设计方案。通过对比单片机和FPGA实现的逻辑电路在电气性能上的差异,可以了解合理地使用FPGA逻辑来加强单片机控制器,可以大幅度地提高系统的性能。

A scheme of large size LED display for characters, which is based on a FPGAenhanced MCU is introduced in this paper. How to use FPGA reasonably to strengthen MCU, andincrease the performance of digital system dramatically is also introducted in this paper.
