说明：  ARM处理器在嵌入式系统中的地位越来越重要，S3C2410作为 ARM9微处理器家族中的一员，应用已十分广泛。文中简述了ARM处理器 的中断异常种类、响应和返回过程；重点讨论了S3C2410中断控制器的结 构和处理机制，以及对IRQ中断的具体处理流程，最后给出了详细的参考
(ARM processors in embedded systems is becoming increasingly important, S3C2410 as ARM9 microprocessor family an application has been very extensive. This paper outlines the ARM processor The interrupt exception type, response and return process focused on the S3C2410 interrupt controller knot Structure and processing mechanisms, and specific processing of IRQ interrupts, finally gives a detailed reference)
