摘要
针对ARM7微控制器的IRQ中断向量地址动态分配在中断向量寄存器中的特点,提出将中断向量固化到ROM中的思路,构建IRQ中断防御体系,从而增强了系统的可靠性和安全性。
This paper aims at the character/stic that the IRQ interrupt vector addresses of ARM7 microcontroller are assigned on the interrupt vector registers dynamic,introduces the idea that roots the interrupt vectors into ROM,establishes the IRQ interrupt recovery system.So the system increases dependability and security.
