摘要
给出了基于S3C44BOX开发板启动代码中的中断管理机制,给出了构造硬件固有中断向量表和软件向量表的方法以及向量表之间的地址映射机制,实现了向量中断和非向量中断的两种响应方式,最后给出了中断系统应用编程的方法和步骤。
Interrupt management mechanism of bootloader based on ARM7 core S3C44B0X control panel is discussed.The conformation method of hardware interrupt vector table and software interrupt vector table are presented,the address mapping mechanism between two tables management is presented.Two response execution processes of vector Interrupt and non-vector Interrupt are implemented.In the end,the programming methods and steps for interrupt system application are introduced.
