摘要
实时任务可调度分析是保证实时系统正确性的重要手段之一。目前现有的基于周期性任务模型的确定性分析方法比较保守 ,不适合于多媒体、通讯等软实时系统的可调度性分析。本文提出一个基于概率的分析方法 。
Real time task schedulability analysis is one of the major methods used to provide performance guarantee to real time systems.The existing deterministic analysis methods based on period task modes are conservative,and are not suitable for soft real time systems such as multimedia systems and communication systems.Therefore,we present a probability based analysis technique to do performance analysis by providing the probability of scheduling tasks to meet the deadline.
