  2. 11. Fault-Tolerance Strategies and Probabilistic Guarantees for Real-Time Systems

    Author : Hüseyin Aysan; Sasikumar Punnekkat; Radu Dobrin; Hans Hansson; Petru Eles; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; embedded systems; real-time systems; fault tolerant design; real-time analysis; dependability analysis; Computer engineering; Datorteknik; Computer Science; datavetenskap;

    Abstract : Ubiquitous deployment of embedded systems is having a substantial impact on our society, since they interact with our lives in many critical real-time applications. Typically, embedded systems used in safety or mission critical applications (e.g. READ MORE

  4. 12. Timing and Schedulability Analysis of Real-Time Systems using Hidden Markov Models

    Author : Anna Friebe; Thomas Nolte; Alessandro Papadopoulos; Filip Markovic; Liliana Cucu-Grosjean; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Abstract : In real-time systems functional requirements are coupled to timing requirements, a specified event needs to occur at the appropriate time.  In order to ensure that timing requirements are fulfilled, there are two main approaches, static and measurement-based. READ MORE

  5. 13. Analysis and Optimisation of Distributed Embedded Systems with Heterogeneous Scheduling Policies

    Author : Traian Pop; Petru Ion Eles; Zebo Peng; Luis Almeida; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Distributed embedded systems; Real-time analysis; Scheduling; Design optimisation; FlexRay; Computer and systems science; Data- och systemvetenskap;

    Abstract : The growing amount and diversity of functions to be implemented by the current and future embedded applications (like, for example, in automotive electronics) have shown that, in many cases, time-triggered and event-triggered functions have to coexist on the computing nodes and to interact over the communication infrastructure. When time-triggered and event-triggered activities have to share the same processing node, a natural way for the execution support can be provided through a hierarchical scheduler. READ MORE

  6. 14. Architectures and Protocols for Performance Improvements of Real-Time Networks

    Author : Kristina Kunert; Magnus Jonsson; Elisabeth Uhlemann; Eduardo Tovar; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Real-time communication; predictable deadline guarantees; real-time scheduling analysis; timing analysis; admission control; deterministic medium access; MAC; Quality of Service parameters; reliability; redundancy; retransmission scheme; ARQ; truncated ARQ; Automatic Repeat Request; wireless networks; IEEE 802.11; IEEE 802.15.4; fibre-optic networks; AWG; multichannel networks; industrial communications; embedded systems; Computer engineering; Datorteknik;

    Abstract : When designing architectures and protocols for data traffic requiring real-time services, one of the major design goals is to guarantee that traffic deadlines can be met. However, many real-time applications also have additional requirements such as high throughput, high reliability, or energy efficiency. READ MORE

  7. 15. Analysis and Synthesis of Heterogeneous Real-Time Systems

    Author : Jakob Axelsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : During the development of a real-time system the main goal is to find an implementation that satisfies the specified timing constraints. Often, it is most cost-effective to use a heterogeneous solution based on a mixture of different microprocessors and application-specific integrated circuits. READ MORE
