  1. 11. Preemption-Delay Aware Schedulability Analysis of Real-Time Systems

    Författare :Filip Marković; Jan Carlson; Radu Dobrin; Björn Lisper; Enrico Bini; Mälardalens högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 12. Mapping Concurrent Applications to Multiprocessor Systems with Multithreaded Processors and Network on Chip-Based Interconnections

    Författare :Ruxandra Pop; Petru Eles; Shashi Kumar; Linköpings universitet; []
    Nyckelord :Network on Chip; Multiprocessor Embedded Systems; Task Mapping; Task Scheduling; Multithreading; Simultaneous Multithreading; Response Time Estimation; Genetic Algorithms; List Scheduling; Soft Deadline; Task Graphs; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Network on Chip (NoC) architectures provide scalable platforms for designing Systems on Chip (SoC) with large number of cores. Developing products and applications using an NoC architecture offers many challenges and opportunities. A tool which can map an application or a set of applications to a given NoC architecture will be essential. LÄS MER

  4. 13. Improving the Schedulability of Real Time Systems under Fixed Preemption Point Scheduling

    Författare :Filip Markovic; Jan Carlson; Radu Dobrin; Björn Lisper; Sebastian Altmeyer; José Javier Gutiérrez; Christian Berger; Mälardalens högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 14. On-Line Monitoring Applications in Nuclear Power Plants

    Författare :Hashem Mehrdad Hashemian; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calibration monitoring; noise analysis; instrumentation and control; sensing line blockages; Nuclear power plants; sensor response time testing; reactor diagnostics; next generation reactors; applied research;

    Sammanfattning : As the current generation of nuclear power plants have passed their mid-life, increased monitoring of their health is critical to their safe operation. This is especially true now that license renewal of nuclear power plants has accelerated, allowing some plants to operate up to 60 years or more. LÄS MER

  7. 15. Modeling and Timing Analysis of Industrial Component-Based Distributed Real-time Embedded Systems

    Författare :Saad Mubeen; Mikael Sjödin; Jukka Mäki-Turja; Per Lindgren; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Distributed real-time embedded systems; component-based development; holistic response-time analysis; component model; timing model; Computer Science; datavetenskap;

    Sammanfattning : The model- and component-based development approach has emerged as an attractive option for the development of Distributed Real-time Embedded (DRE) systems. In this thesis we target several issues such as modeling of legacy communication, extraction of end-to-end timing models and support for holistic response-time analysis of industrial component-based DRE systems.
