  1. 1. Testability of Dynamic Real-Time Systems

    Författare :Birgitta Lindström; Sten F. Andler; Jeff Offutt; Paul Pettersson; Zebo Peng; Lionel Briand; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Testability; Software testing; Real-time systems; Timeliness; Model-based testing; Computer science; Datalogi; Teknik;

    Sammanfattning : This dissertation concerns testability of event-triggered real-time systems. Real-time systems are known to be hard to test because they are required to function correct both with respect to what the system does and when it does it. LÄS MER

  3. 2. Energy Efficient and Predictable Design of Real-Time Embedded Systems

    Författare :Alexandru Andrei; Petru Eles; Zebo Peng; Lothar Thiele; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Embedded Systems; Real-Time; System level design; Power Optimization; Predictability; Computer science; Datavetenskap;

    Sammanfattning : This thesis addresses several issues related to the design and optimization of embedded systems. In particular, in the context of time-constrained embedded systems, the thesis investigates two problems: the minimization of the energy consumption and the implementation of predictable applications on multiprocessor system-on-chip platforms.

  4. 3. Towards Aspectual Component-Based Real-Time System Development

    Författare :Aleksandra Tešanović; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aspect-oriented software development; component-based software development; real-time systems; embedded systems; database systems; aspects; components; worst-case execution time; Computer science; Datavetenskap;

    Sammanfattning : Increasing complexity of real-time systems and demands for enabling their configurability and tailorability are strong motivations for applying new software engineering principles such as aspect-oriented and component-based software development. The integration of these two techniques into real-time systems development would enable: (i) efficient system configuration from the components in the component library based on the system requirements, (ii) easy tailoring of components and/or a system for a specific application by changing the behavior (code) of the component by aspect weaving, and (iii) enhanced flexibility of the real-time and embedded software through the notion of system configurability and component tailorability.

  5. 4. Enhancing the Performance of Distributed Real-time Systems

    Författare :Hoai Hoang; Magnus Jonsson; Bertil Svensson; Luís Almeida; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Switched Ethernet; Real-Time Communication; EDF scheduling; Reducation of delay and jitter; Computer science; Datalogi;

    Sammanfattning : Advanced embedded systems can consist of many sensors, actuators and processors that are deployed on one or several boards, while having a demand of interacting with each other and sharing resources. Communication between different components usually has strict timing constraints. LÄS MER

  7. 5. Memory Efficient Hard Real-Time Garbage Collection

    Författare :Tobias Ritzau; Peter Fritzson; Roger Henriksson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hardware progresses; programming languages; garbage collector; real-time reference counting; object ownership; static garbage collector; embedded systems; Computer science; Datavetenskap;

    Sammanfattning : As the development of hardware progresses, computers are expected to solve increasingly complex problems. However, solving more complex problems requires more complex software. To be able to develop these software systems, new programming languages with new features and higher abstraction levels are introduced. LÄS MER
