基于LEON3软核CPU的异步全彩LED显示控制系统

An asynchronous full-color LED display control system based on the LEON3 soft core CPU

文章介绍了一种异步全彩LED显示控制系统。该系统以LEON3^([1])软核CPU及其配套的嵌入式Linux系统作为显示系统的管理与流程控制开发平台,采用Verilog语言实现视频数据并行处理及LED显示屏的扫描显示。本系统的使用比传统的异步LED显示控制系统功耗、成本更低、性能更高的同时,还提高了系统的集成度及可靠性。

This paper introduces an asynchronous full-color LED display control system. The system with LEON3 [1] soft core CPU and embedded Linux system as a display system of management and process control development platform, using Verilog language to implement the data parallel processing and LED display video scan display. The use of this system not only lower power consumption and lower cost and higher performance but also more reliable than conventional asynchronous LED display control system.
