Hard real time scheduling considerations
WebIt sounds like real-time scheduling is more critical and difficult than traditional time-sharing, and in many ways it is. But real-time systems may have a few characteristics that make scheduling easier: We may actually know how long each task will take to run. This enables much more intelligent scheduling. Starvation (of low priority tasks ... WebApr 8, 2024 · Abstract. In multicore scheduling of hard real-time systems, there is a significant source of unpredictability due to the interference caused by the sharing of hardware resources. This paper deals with the schedulability analysis of multicore systems where the interference caused by the sharing of hardware resources is taken into account.
