摘　　要：针对嵌入式实时系统设计中,前后台系统实时性差,实时内核开销大的问题,利用中断与实时任务本身特点,提出并设计实现了基于中断的实时任务调度策略,在不增加系统资源开销、价格开销的情况下达到与采用实时内核相当的实时性能。The foreground/background system has a poor real-time performance and the real-time kernel usually costs too much. This paper designs and realizes an interrupt-based strategy of real-time tasks scheduling, considering the characteristics of the interrupt and the real-time tasks. This strategy can reach the same performance of the real-time kernel without increasing the extra cost.

关 键 词：中断 实时 调度
