摘　　要：为了提高数字信号处理器的实时处理能力,提出了一种改进的中断处理系统。在传统中断系统的基础上增加了协处理器来专门处理中断请求,减小中央处理器的负荷。引入可编程的中断请求节点配合灵活的中断向量表,提高了中断系统的灵活性。仿真结果表明,设计实现了处理器处理中断事件的作用,可实现中断的灵活配置。To improve the real-time processing ability of the digital signal processing （DSP）, a design of improved interrupt handling system is presented. A co-processor is introduced to handle the interrupt request based on the traditional interrupt system, which reduces the load of the central processor. In addition, the programmable interrupt request nodes with a flexible interrupt vector table are proposed to improve the flexibility of the interrupt system. The simulation results are presented to prove the designed processor can handle the interrupt event and realize flexible configuration of the interrupt.
