实时系统中分层调度机制研究

Hierarchical Scheduling Method in Real-time System

以Linux内核为例分析了实时应用方面的不足之处,并对近年来实时任务调度的研究进行综合分析,以此为基础提出了一种分层调度结构。该结构保证了实时应用的即时调度,较好地运用了已有的Linux内核资源,并使得实时与非实时任务间的相互通信更加通畅。

The deficiency of real - time applications base on Hnux kernel is analysed, and the research on real -time tasks scheduling recently, according to these work, the paper proposes a framework of hierarchical scheduling in real- time operation system, The framework not only satisfies real- time applications, uses Linux kernel service very well, but also makes a good communication between real - time tasks and non real - time tasks.
