摘　　要：该文采用基于嵌入式实时操作系统的ARM微处理器技术,设计了一种全彩LED显示屏控制系统。该系统以ARM微处理器为核心,在可编程逻辑器件CPLD控制下,完成显示数据传输与更新、动态画面的刷新、循环扫描显示等功能。该系统能脱机和连续长期运行,性能稳定、可靠。Based on the technology of embedded real - time operating system and high performance of ARM MPU, a kind of large LED color screen display control system was designed. Under the control of core chip ARM MPU, with the help of programmable logic device CPLD, the control system finished the data store and update, dynamic cartoon processing, circulation showing etc. This system can work in off line state and run for a long time in succession, steady and reliability.
