基于龙芯1A平台的PMON源码编译和启动分析

摘要

为降低开发人员理解龙芯(MIPS32)和 PMON 源码的难度，对基于龙芯1A 平台的 PMON 源码编译和启动进行分析。采用流程图和文字相结合的形式，对PMON的目录结构、编译方法和执行流程进行研究。结果表明：该方法能清晰地展示PMON的编译和启动时期的工作机理，可为相关人员了解PMON工作方式和修改编译其源代码提供帮助。%For decreasing difficulties of researcher understanding Loongson(MIPS32) and PMON source codes, analyze the compiling and starting of PMON source code based on Loongson 1A platform. Combine flow charts with character, research content structure, compiling method and execution process of PMON. The results show that the method can give a clear illustration about PMON’s operating principle in compile-time and start-time. This article may help new developers and anyone interested in PMON learn and modify the source code.
