  1. 6. Efficient Memory Utilization in Resource Constrained Real-Time Systems

    Författare :Kaj Hänninen; Mikael Nolin; Robert Davis; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stack sharing; Real-Time systems; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : This thesis presents design and run-time techniques for efficient memory utilization in embedded real-time systems. The proposed techniques give developers means to reduce the memory consumption in the systems. LÄS MER

  3. 7. Hierarchical Real Time Scheduling and Synchronization

    Författare :Moris Behnam; Mikael Sjödin; Thomas Nolte; Björn Andersson; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer engineering; Datorteknik; Datavetenskap;

    Sammanfattning :   The Hierarchical Scheduling Framework (HSF) has been introduced to enable compositional schedulability analysis and execution of embedded software systems with real-time constraints. In this thesis, we consider a system consisting of a number of semi-independent components called subsystems, and these subsystems are allowed to share logical resources. LÄS MER

  4. 8. Introducing a Memory Efficient Execution Model in a Tool-Suite for Real-Time Systems

    Författare :Kaj Hänninen; Mikael Nolin; Christer Norström; Jukka Mäki-Turja; Ola Redell; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-Time Systems; Execution Models; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : This thesis shows how development of embedded real-time systems can be made more efficient by introduction of an memory efficient execution model in a commercial development suite. To identify the need of additional support for execution models in development tools, the thesis investigate by a series of interviews, the common requirements in development of industrial embedded real-time systems.

  5. 9. Deterministic replay debugging of embedded real-time systems using standard components

    Författare :Daniel Sundmark; Mälardalens universitet; []
    Nyckelord :;

    Sammanfattning : Men and women make mistakes. They always have and they alwayswill. Naturally, software engineers are no exception to thisrule. When software engineers make their mistakes, these manifest inthe form of buggy software. LÄS MER

  7. 10. Stability of Adaptive Distributed Real-TimeSystems with Dynamic Resource Management

    Författare :Sergiu Rafiliu; Petru Eles; Zebo Peng; Luigi Palopoli; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; real-time systems; distributed embedded systems; control systems; scheduling; adaptive system;

    Sammanfattning : Today's embedded distributed real-time systems, are exposed to large variations in resource usage due to complex software applications, sophisticated hardware platforms, and the impact of their run-time environment. As eciency becomes more important, the applications running on these systems are extended with on-line resource managers whose job is to adapt the system in the face of such variations. LÄS MER
