Abstract: This paper designs a new asynchronous LED display control system based on ARM and CPLD, the core of the system is Cortex-M3, CPLD is the scan control unit, the communication with the PC is accomplished by the Ethernet. It can storage and play automatically, the contents of the host computer can be stored in Flash, the contents can be displayed on the LED screen. The system provides crystal clear and stable picture, and can be maintained conveniently.

Key words: Cortex-M3, asynchronous, LED display control
