From Instantaneous Schedulability to Worst Case Schedulability: A Significant Moment Approach [article]

Ningshi Yao, Fumin Zhang
2021 arXiv   pre-print
The method of significant moment analysis has been employed to derive instantaneous schedulability tests for real-time systems.  ...  However, the instantaneous schedulability can only be checked within a finite time window. On the other hand, worst-case schedulability guarantees schedulability of systems for infinite time.  ...  We revisit Liu and Layland's canonical task sets and utilize the significant moment analysis to derive the same set of worst case schedulability conditions under RMS.  ...
