HT—RTU操作系统实时调度算法

Realtime Process Algorithm of HT-RTU OS

本文首先引出了UNIX操作系统进程调度的实时改造问题,给出实时化原则,然后从实时调度标志、优先数设置、就绪进程排队策略、AST自陷重调度、进程对换策略等五个方面对调度算法进行了详细的实时化设计,给出了切实可行的方案。

First, the paper introduces the topic of realtime with UNIX, and the rules ofrealtime. Then the paper presents the design idea of realtime process algorithm from 5 as-pects of realtime flag, priority settinies, the strategies of process queue, AST reschedulingand process scheduling.
