摘　　要：嵌入式系统移植是嵌入式开发中经常遇到的问题。本文以龙芯3A处理器为载体,根据其通用异常处理机制和硬件资源配置,完成系统的启动,并对串口驱动进行开发与配置,成功将实时嵌入式道系统(DeltaOS)移植到龙芯3A平台上,为应用程序和驱动程序的开发提供了必要的基础。In the development of embedded system application, the transplantation is a frequently encountered problem. In the paper, taking the Loogson3A processor as the carrier, according to its exception handing mechanism and configuration of hardware resources, the design completes the startup of system, develops and configurates the driver of serial port. The embedded real-time system DeltaOS is transplanted on the Loogson3A successfully,which provides the necessary foundation for the application and other driver development.
