Abstract: 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.
