  1. 1. 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. 2. Static Execution Time Analysis of Parallel Systems

    Författare :Andreas Gustavsson; Björn Lisper; Jan Gustafsson; Andreas Ermedahl; David Broman; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; WCET analysis; parallel systems; multi-core; multicore; threaded programming language; Computer Science; datavetenskap;

    Sammanfattning : The past trend of increasing processor throughput by increasing the clock frequency and the instruction level parallelism is no longer feasible due to extensive power consumption and heat dissipation. Therefore, the current trend in computer hardware design is to expose explicit parallelism to the software level. LÄS MER

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

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

    Sammanfattning : 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.

  5. 4. Strategic time awareness : implications of strategic thinking

    Författare :Henrik Friman; Peter Stevrin; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Strategic time; strategic time awareness; strategic thinking and strategic management; Business Administration; företagsekonomi;

    Sammanfattning : Strategic time awareness (STA) is a research project that strives to gain new insights about the strategic thinking process and better understand time in the context of strategic management. The purpose of this study is to understand what managers think is important with regard to time in the process of strategic thinking. LÄS MER

  7. 5. Parametric WCET Analysis

    Författare :Stefan Bygde; Björn Lisper; Raimund Kirner; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; WCET Analysis; parametric WCET Analysis; WCET; Timing; Computer Science; datavetenskap;

    Sammanfattning : In a real-time system, it is crucial to ensure that all tasks of the system hold their deadlines. A missed deadline in a real-time system means that the system has not been able to function correctly. If the system is safety critical, this could potentially lead to disaster. LÄS MER
