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。
The article introduces an asynchronous full color LED display control system. The system uses LEON3 ~ ([1]) soft-core CPU and its supporting embedded Linux system as a display system management and process control development platform, using Verilog language video data parallel processing and LED display of the scan display. The use of the system than traditional asynchronous LED display control system power consumption, lower cost, higher performance, but also improve the system’s integration and reliability.
