摘要
文章建立了实时中间件OPC服务器的实时调度模型,设计了处理混合任务的动态调度算法(基于EDF)和实现方式,分析了算法的可调度性和非周期任务的响应性能及参数设计,并给出了相应的调度结果。
The paper presents real-time scheduling model of real-time middleware OPC,designs dynamic scheduling al-gorithms ,deals with hybrid tasks and implementation(based on EDF),and analyzes the schedulability and response per-formances and parameters of aperiodic tasks.In last,the paper shows scheduling result of the algorithms.
