基于FPGA的LED显示控制系统设计

LED产业是21世纪最具有发展前景的高新技术产业。根据LED显示模块结构特点,应用FPGA技术对LED显示屏的控制系统进行设计。显示控制系统由输入接口模块、信号写入控制模块、信号读取控制模块、读取控制模块、存储模块、动态控制模块等模块构成。程序采用Verilog-HDL语言编写,从而实现外部输入信号的地址生成、选择、存储、动态控制等处理。实验测试结果表明:系统可以实现字符或图案的动态显示,具有实际应用价值。

Design Of LED Display Control System Based on FPGA

LED industry is the most promising high-tech industry in the 21st century, according to the structural characteristics of the LED display module, combining with FPGA technology, it designed a large-screen LED display control system. Display control system consists of input interface modules, signal write control module, the signal read control module, read control module, memory module and dynamic control modules, using Verilog-HDL language for programming, the design achieved a series of processing of the external input signal, including the address generation, selection, storage and dynamic control. The experimental results show that: the system can realize the dynamic display of character or pattern, has a practical application.
