ARM编程特别是系统初始化代码的编写中通常需要实现中断的响应、解析跳转和返回等操作，以便支持上层应用程序的开发，而这往往是困扰初学者的一个难题。中断处理的编程实现需要深入了解ARM内核和处理器本身的中断特征，从而设计一种快速简便的中断处理机制。需要说明的是，具体的上层高级语言编写的中断服务函数不在本文的讨论范围之内(ARM programming particular system initialization code in preparation usually need to achieve interruption of response Jump and return analysis, etc, in order to support the upper application development, which is often plagued by a problem beginners. Interruption of programming needs in-depth understanding of the ARM processor core and features of the interruption itself, be able to design a simple and rapid interrupt handling mechanism. There is a need to explain the specific upper prepared by the high-level language service interruption is not the function within the scope of discussion)
