  2. 1. Limited Preemptive Scheduling in Real-time Systems

    Author : Abhilash Thekkilakattil; Sasikumar Punnekkat; Radu Dobrin; Reinder Bril; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Abstract : Preemptive and non-preemptive scheduling paradigms typically introduce undesirable side effects when scheduling real-time tasks, mainly in the form of preemption overheads and blocking, that potentially compromise timeliness guarantees. The high preemption overheads in preemptive real-time scheduling may imply high resource utilization, often requiring significant over-provisioning, e. READ MORE

  4. 2. Preemption-Delay Aware Schedulability Analysis of Real-Time Systems

    Author : Filip Marković; Jan Carlson; Radu Dobrin; Björn Lisper; Enrico Bini; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-time systems; Scheduling; Schedulability analysis; Preemptions; Preemption delays; Embedded Systems; Preemptive scheduling; Response-time analysis; Cache-related preemption delay; Timing analysis; Worst-case execution time analysis; Limited-preemptive scheduling; Fixed preemption points; Computer Science; datavetenskap;

    Abstract : Schedulability analysis of real-time systems under preemptive scheduling may often lead to false-negative results, deeming a schedulable taskset being unschedulable. This is the case due to the inherent over-approximation of many time-related parameters such as task execution time, system delays, etc. READ MORE

  5. 3. Improving the Schedulability of Real Time Systems under Fixed Preemption Point Scheduling

    Author : Filip Markovic; Jan Carlson; Radu Dobrin; Björn Lisper; Sebastian Altmeyer; José Javier Gutiérrez; Christian Berger; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Real-Time Systems; Limited Preemptive Scheduling; Fixed Preemption Points Scheduling; Probabilistic response time analysis; Cache-Related Preemption Delay Analysis; Computer Science; datavetenskap;

    Abstract : During the past decades of research in Real-Time systems, non-preemptive scheduling and fully preemptive scheduling have been extensively investigated, as well as compared with each other. However, it has been shown that none of the two scheduling paradigms dominates over the other in terms of schedulability. READ MORE
