摘要

提出了一种高性能数字信号处理器中断系统结构，通过中断优先级的灵活可变以及系统仲裁周期的可选择性，提高中断系统的执行效率。由于中断向量表的中断服务例程的可跨越性和中断优先级分组两个特点，提高了中断优先级排列的灵活实用性。通过引入外设控制处理器来作为中断服务的提供商，增加了中断处理的途径。理论分析与仿真结果表明达到了系统中断功能的要求。

Abstract

A high performance digital signal processor (DSP) interrupt system has been proposed.By providing a flexible interrupt service request priority and an optional number of arbitration cycles

the execution efficiency of the interrupt system can be improved.Due to the two characteristics of the interrupt vector table

spanning interrupt service routines across vector entries and grouping interrupt priority

the practicability of the priority-based interrupt system is improved.By introducing the peripheral control processor (PCP) as a new interrupt service provider

an additional interrupt processing way is provided.The theoretical analysis and simulation results indicate that the requirements of the interrupt system have been satisfied.
