摘要
本文介绍了ARMS3C2410X系统的异常中断响应和返回过程,重点讨论了ARMS3C2410X系统中采用IRQ响应外设向CPU请求服务的中断编程机制,并用一个实例展示这种中断编程机制的应用。
In the text the process of interrupt response and resume of ARM S3C2410X system is presented. An interrupt programming mechanism is discussed emphatically, which is that S3C2410X system use IRQ achieve the request from peripheral equipment to CPU. And the application of this kind of interrupt programming mechanism is demonstrated with a example.
