摘要
目前小型嵌入式操作系统的中断管理实现的不足主要表现在:对硬件依赖性强;安全性差;实时性差等。本文针对这些问题提出了一种中断管理实现。它采用分层设计,降低硬件依赖性;通过构建较中断向量表,提供可扩展的中断优先级;调整中断管理策略,改善实时性中断的响应。
At present the general implementation of interrupt manager in small-scaled embedded operating system exhibits high dependence on hardware, poor safety and real time. According to these problems, we raised a new implementation . It decreases the dependence on hardware through layered design. It provides extendable interrupt priority by using soft interrupt vector. It improves ability in real time interrupt management by changing the policy.
