| 摘 要： | 在建立了同时中断优先级和并发中断优先级等概念的基础上,分析了中断响应过程,用中断处理次序概念从本质上描述中断处理中的优先含义,从而实现对系统机中中断源处理的优先级别的自由调整。给出了在PC系列机环境下,改变并发中断优先级,实现理想的中断处理顺序调整的具体方法。

| Abstract: | Following the establishment of the concepts,simultaneity interrupt priority and concurrent interrupt priority,interrupt response processing is analyzed in detail and the essentials of priority meanings in interrupt processing is depicted.Consequently the freewill adjustment of interrupt priority is implemented.Moreover the methods of changing the concurrence interrupt priority and implementing ideal interrupt process order is presented under PC and compatible computer environment. |
