| 摘 要： | 本文介绍了多任务版本的实时系统调度算法.该算法能够满足实时系统中的关键性任务在最坏情况下运行时,仍可满足截止时闻的要求.通过为实时系统中的关键性任务设置两个任务版本,即主态和从态版本.主态任务版本具有较好的质量,从态任务版本只提供最基本的功能,运行时间较短.在最坏情况下避免调度主态任务版本,来满足实时调度的实时性要求.

| Abstract: | In this paper,we presented Multiple task version scheduling.The scheduling ensures that critical tasks will complete before their deadline even under its worst-case time in real-time system.For each critical task,we have two versions,a primary and an alternative.The primary may be capable of providing better-quality service,while the alternative is a "bare-bone"version that provides service that is just capable.The alternative version has a much smaller worst-case execution time than the primary.So we can a... |
