基于FPGA的LED大屏幕控制系统的设计与实现

Design and implementation of FPGA-based LED large-screen control system

基于FPGA芯片EP2CQ208C设计了一种低成本、高性能的LED大屏幕控制系统。结合现有系统特点,对SDRAM乒乓式数据缓存提出了改进,同时提出了反γ校正与灰度级调节、颜色调节等在FPGA中的实现。

This paper designed a low-cost, high performance LED large screen control system, based on FPGA chip EP2CQ208C. According to the existing systems, the system proposed some improvements on Ping-Pong type SDRAM data cache and the implementation of gamma correction and color adjustment in FPGA.
