摘　　要：PMON是一种针对嵌入式系统而设计的类BIOS引导程序。为了在龙芯平台上为各种应用系统提供PMON的支持,从PMON2000的基本架构出发,研究并实现在龙芯Mipsel平台上的PMON2000基本框架。首先对PMON的整体框架进行了认知与分解,指出根据龙芯Mipsel平台的独特性对PMON文件系统目录中的各种系统文件进行移植是设计过程中的难点。在此基础上,利用汇编语言实现对硬件的基本初始化,使用C语言实现对南北桥芯片以及显卡等信息的初始化工作。通过在龙芯系列平台的运行,验证了该设计的可行性和正确性。PMON is a bootstrap program similar BIOS for embedded systems designed.To provide PMON support for the various ap-plication systems on the Loongson platform,the basic framework of PMON for the Loongson Mipsel platform with PMON2000 basic framework is researched and realized.Firstly,the overall framework of PMON is recognized and decomposed.It is pointed out that the difficulty in scheme design is to transplant the variety of system files within the PMON file system directory based on the uniqueness of Loongson Mipsel platform.On this basis,the assembly language is used to achieve the basic initialization of hardware,and the C language is applied for the realization of initializing the south and north bridge chip,as well as graphics.Finally,by running on Loongson series platform,the feasibility and correctness of the presented method is demonstrated.
