  3. 2. Fibre-Optic AWG Networks Supporting Real-Time Communication in High-Performance Embedded Systems

    Författare :Kristina Kunert; Magnus Jonsson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; real-time communication; medium access control MAC protocol; traffic dependency analysis; network architecture; Arrayed Waveguide Grating AWG ; optical communication; real-time analysis; optical network; Real-time communication; fiber-optic communication; Computer engineering; Datorteknik;

    Sammanfattning : High-performance embedded systems communicating heterogeneous traffic with high bandwidth and strict timing requirements are in need of more efficient communication solutions. This thesis proposes two multi-wavelength passive optical networks able to meet these demands. LÄS MER

  4. 3. Testability of Dynamic Real-Time Systems

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

    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

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

    Författare :Tobias Ritzau; Peter Fritzson; Roger Henriksson; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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

  7. 5. Automatic memory management for flexible real-time systems

    Författare :Sven Robertz; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer science; feedback scheduling; embedded systems; real-time; memory management; garbage collection; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll;

    Sammanfattning : In a flexible real-time system, the constraints in available CPU time and memory lead to resource management problems, which must be handled carefully in order to maximize quality of service while avoiding overload. Managing CPU time -- scheduling -- is well studied and dynamic scheduling is widely accepted in the real-time industry. LÄS MER
