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

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :Filip Marković; Jan Carlson; Radu Dobrin; Björn Lisper; Enrico Bini; [2020]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  2. 2. Resource Management in Computing Systems

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :Payam Amani; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Resource management is an essential building block of any modern computer and communication network. In this thesis, the results of our research in the following two tracks are summarized in four papers. The first track includes three papers and covers modeling, prediction and control for multi-tier computing systems. LÄS MER

  3. 3. Real-Time Control Systems with Delays

    Detta är en avhandling från Department of Automatic Control, Lund Institute of Technology (LTH)

    Författare :Johan Nilsson; [1998]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Timing jitter; Stochastic parameters; Stochastic control; Real-time systems; Linear quadratic control; Jump linear systems; Distributed computer control systems; Clock synchronization; Delay compensation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Control loops that are closed over a communication network get more and more common. A problem with such systems is that the transfer delays will be varying with different characteristics depending on the network hardware and software. LÄS MER

  4. 4. Predictable Real-Time Applications on Multiprocessor Systems-on-Chip

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Jakob Rosén; Zebo Peng; Petru Eles; Thomas Nolte; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Systems; Embedded Systems; Real-Time Systems; Predictability; Multiprocessor Systems; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Sammanfattning : Being predictable with respect to time is, by definition, a fundamental requirement for any real-time system. Modern multiprocessor systems impose a challenge in this context, due to resource sharing conflicts causing memory transfers to become unpredictable. LÄS MER

  5. 5. Hybrid observers for systems with intrinsic pulse-modulated feedback

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Diana Yamalova; Alexander Medvedev; Xiaoming Hu; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid systems; impulsive systems; biomedical systems; Goodwin s oscillator; observers; time-delay; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : Dynamical processes resulting from the interaction of continuous and discrete dynamics are often encountered in living organisms. Time evolutions of such processes constitute continuous variables that are subject to instant changes at discrete points of time. LÄS MER
