  2. 1. 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

  4. 2. Real-Time Workload Models : Expressiveness vs. Analysis Efficiency

    Author : Martin Stigge; Wang Yi; Sanjoy Baruah; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; task models; EDF; fixed-priority scheduling; schedulability analysis; response-time analysis; abstraction refinement; Computer Science with specialization in Real Time Systems; Datavetenskap med inriktning mot realtidssystem;

    Abstract : The requirements for real-time systems in safety-critical applications typically contain strict timing constraints. The design of such a system must be subject to extensive validation to guarantee that critical timing constraints will never be violated while the system operates. READ MORE

  6. 4. Schedulability analysis of real-time systems with stochastic task execution times

    Author : Sorin Manolache; Petru Eles; Zebo Peng; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datorsystem; Embedded systems; Real-time systems; Stochastic execution times; Performance analysis; Datorsystem; Computer science; Datavetenskap;

    Abstract : Systems controlled by embedded computers become indispensable in our lives and can be found in avionics, automotive industry, home appliances, medicine, telecommunication industry, mecatronics, space industry, etc. Fast, accurate and flexible performance estimation tools giving feedback to the designer in every design phase are a vital part of a design process capable to produce high quality designs of such embedded systems.

  7. 5. New Techniques for Building Timing-Predictable Embedded Systems

    Author : Nan Guan; Wang Yi; Lothar Thiele; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; WCET analysis; cache analysis; abstract interpretation; multiprocessor scheduling; fixed-priority scheduling; EDF; multi-core processors; response time analysis; utilization bound; real-time calculus; scalability; Datavetenskap med inriktning mot realtidssystem; Computer Science with specialization in Real Time Systems;

    Abstract : Embedded systems are becoming ubiquitous in our daily life. Due to close interaction with physical world, embedded systems are typically subject to timing constraints. At design time, it must be ensured that the run-time behaviors of such systems satisfy the pre-specified timing constraints under any circumstance. READ MORE
