ARM处理器启动代码分析与设计

Analysis and design on the boot-up code in ARM microprocessor

本文以LPC2114 ARM处理器为例,结合具体代码详细分析了中断向量表设计、各处理器模式堆栈初始化、分散加载文件设计及使用C运行时库所需要的重载函数。深入理解ARM7启动代码将有助于后续应用程序的开发。

Based on LPCZ114 microprocessor,a detail analysis about some procedures is given in this paper and the procedures in clude the design of an interrupt vecfor table and scaffer load file,the stack initiallzation for various processor models and some overloaded functions in the application of C rurring library.This is very benefit for the development of lafer application program.
