摘　　要：阐述以高性能SOC TMS320C66AK2H的Cortex A15内核为例,利用Cortex A15内核中断控制器(GIC 400)和SOC中断处理控制器(CIC2)实现一个系统异常处理机制,能够准确快速的定位系统运行出错的地方。以Cortex A15内核使用EDMA3模块非法访问共享内存MSMC为例,验证系统异常处理机制的可行性,经测试该方法准确有效。This paper expounds the Cortex A15 kernel of high-performance SOC TMS320C66AK2H,and implements a system exception handling mechanism using the Cortex A15 kernel interrupt controller(GIC 400)and SOC interrupt handling controller(CIC2),which can accurately and quickly locate the errors in system operation.Taking the Cortex A15 kernel as an example of illegally accessing shared memory MSMC using the EDMA3 module,it verifies the feasibility of the system's exception handling mechanism and has been tested to be accurate and effective.
