ARM映像文件机理分析及其应用

Analysis and Application of ARM Mapping File Mechanism

阐述了基于ARM体系结构的映像文件机理,介绍了它的组成、生成方法以及加载运行过程。其中重点分析了映像文件在不同的ARM嵌入式应用系统中的加载运行情况,并给出了部分实现代码,且在最后给以总结,以便编程设计人员在开发中能更好地应用它。

This article clarifies the mechanism of the mapping file in the ARM architecture, and introduces the compose of the mapping file, the method by which the mapping file is built and the process of the mapping file load and execution. Especially, it emphatically analyses the load time and execution time of the mapping file in the different ARM embedded system, then gives the implementation code. Finally it draws a conclusion.
