Best-case response times of real-time tasks under fixed-priority scheduling with preemption thresholds
Hector J. Rivera-Verduzco, Reinder J. Bril · 2017
Compared to fixed-priority preemptive scheduling (FPPS), fixed-priority scheduling with preemption thresholds (FPTS) reduces memory requirements, the cost of arbitrary preemptions, and it has been shown to improve the schedulability ratio of task-sets. FPTS has been viewed as a potential successor to FPPS as a de facto standard in industry, where it is already supported by both OSEK and AUTOSAR compliant operating systems.
