  1. 1. 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

  3. 2. Static Timing Analysis of Parallel Systems Using Abstract Execution

    Författare :Andreas Gustavsson; Björn Lisper; Jan Gustafsson; Andreas Ermedahl; Nan Guan; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; WCET analysis; parallel systems; multi-core; multicore; threaded programming language; Computer Science; datavetenskap;

    Sammanfattning : The Power Wall has stopped the past trend of increasing processor throughput by increasing the clock frequency and the instruction level parallelism.Therefore, the current trend in computer hardware design is to expose explicit parallelism to the software level. LÄS MER

  4. 3. A Modular Tool Architecture for Worst-Case Execution Time Analysis

    Författare :Andreas Ermedahl; Hans Hansson; Reinhard Wilhelm; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer engineering; Datorteknik; Computer Systems; Datorteknik;

    Sammanfattning : Estimations of the Worst-Case Execution Time (WCET) are required in providing guarantees for timing of programs used in computer controlled products and other real-time computer systems. To derive program WCET estimates, both the properties of the software and the hardware must be considered. LÄS MER

  5. 4. Static WCET Analysis Based on Abstract Interpretation and Counting of Elements

    Författare :Stefan Bygde; Björn Lisper; Andreas Ermedahl; Jan Gustafsson; Konstantinos Sagonas; Ulf Nilsson; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parametric WCET analysis; program analysis; abstract interpretation; Computer science; Datalogi; Computer Science; datavetenskap;

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

  7. 5. Utilizing Hardware Monitoring to Improve the Quality of Service and Performance of Industrial Systems

    Författare :Marcus Jägemar; Björn Lisper; Moris Behnam; Sigrid Eldh; Andreas Ermedahl; Håkan Grahn; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning : The drastically increased use of information and communications technology has resulted in a growing demand for telecommunication network capacity. The demand for radically increased network capacity coincides with industrial cost-reductions due to an increasingly competitive telecommunication market. LÄS MER
