  1. 6. Adaptive Hierarchical Scheduling Framework for Real-Time Systems

    Författare :Nima Khalilzad; Thomas Nolte; Martina Maggio; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Sammanfattning : Modern computer systems are often designed to play a multipurpose role. Therefore, they are capable of running a number of software tasks (software programs) simultaneously in parallel. These software tasks should share the processor such that all of them run and finish their computations as expected. LÄS MER

  3. 7. Towards a Predictable Component-Based Run-Time System

    Författare :Rafia Inam; Mikael Sjödin; Jukka Mäki-Turja; Tullio Vardanega; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; real-time systems; component based software engineering; hierarchical scheduling; Computer Science; datavetenskap;

    Sammanfattning : In this thesis we propose a technique to preserve the temporal properties of realtime components during their integration and reuse. We propose a new concept of runnable virtual node which is a coarse-grained real-time component that provides functional and temporal isolation with respect to its environment. LÄS MER

  4. 8. Exploiting Fine-grain Parallelism in Concurrent Constraint Languages

    Författare :Johan Montelius; RISE; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Implicit parallelism; Concurrent Constraint Programming; Cache performance; Logic programming; Abstract machine; Parallel execution; Scheduling; Multiprocessor; Shared memory;

    Sammanfattning : This dissertation presents the design, implementation, and evaluation of a system that exploits fine-grain implicit parallelism in concurrent constraint programming language. The system is able to outperform a C implementation of an algorithm with complex dependencies without any user annotations. LÄS MER

  5. 9. On the Development of Hierarchical Real-Time Systems

    Författare :Mikael Åsberg; Thomas Nolte; Tommaso Cucinotta; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning : Hierarchical scheduling (also referred to as resource reservation) is a hot topic within the research of real-time systems. It has many advantages such that it can facilitate software integration, fault isolation, structured analysis, legacy system integration etc. LÄS MER

  7. 10. Synchronization Protocols for a Compositional Real-Time Scheduling Framework

    Författare :Moris Behnam; Thomas Nolte; Mikael Sjödin; Giuseppe Lipare; Mälardalens högskola; []
    Nyckelord :Computer Science; datavetenskap;

    Sammanfattning : In this thesis we propose techniques to simplify the integration of subsystems while minimizing the overall amount of CPU resources needed to guarantee the schedulability of real-time tasks. In addition, we provide solutions to the problem of allowing for the use of logical resources requiring mutual exclusion. LÄS MER
