  1. 16. Measurement and Simulation Based Techniques for Real-Time Systems Analysis

    Författare :Markus Lindgren; Hans Hansson; Jörgen Hansson; Uppsala University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Datavetenskap;

    Sammanfattning : Rigorous methods for design and implementation of safety critical real-time systems are vital to avoid loss of human lives and/or severe economic losses.  Unfortunately, many of these systems are designed and evaluated using ad-hoc techniques. LÄS MER

  3. 17. 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. 18. Analyzing execution-time of object-oriented programs using abstract interpretation

    Författare :Jan Gustafsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information technology; Informationsteknik; Computer Systems; Datorteknik;

    Sammanfattning : As a result of the industrial deployment of real-time systems, there is an increasing demandfor methods to perform safe and tight calculation of the worst case execution time (WCET) ofprograms. The WCET is a necessary prerequisite for guaranteeing correct timing behaviour ofreal-time systems. LÄS MER

  5. 19. A Generic Approach to Schedulability Analysis of Real-Time Systems

    Författare :Elena Fersman; Wang Yi; Ed Brinksma; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : This thesis presents a framework for design, analysis, and implementation of embedded systems. We adopt a model of timed automata extended with asynchronous processes i.e. tasks triggered by events. LÄS MER

  7. 20. Fault Tolerance for Real-Time Systems: Analysis and Optimization of Roll-back Recovery with Checkpointing

    Författare :Dimitar Nikolov; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft errors; fault tolerance; real-time systems; checkpointing; reliability;

    Sammanfattning : Increasing soft error rates in recent semiconductor technologies enforce the usage of fault tolerance. While fault tolerance enables correct operation in the presence of soft errors, it usually introduces a time overhead. LÄS MER
