  2. 16. Efficient parallell architectures for future radar signal processing

    Author : Anders Åhlander; John L. Gustafson; Högskolan i Halmstad; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer architecture; radar signal processing; space-time adaptive processing; synthetic aperture radar; parallel processing; engineering efficiency; Computer science; Datalogi;

    Abstract : The processing demands on future embedded radar signal processors may stretch to several trillions of floating-point operations per second (TFLOPS). This is an increase of two to three orders of magnitude realtive to the requirements of today. Still, the tight size and power constraints are unchanged. READ MORE

  4. 17. Techniques for software implemented fault tolerance

    Author : Ruben Alexandersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fault tolerance; aspect oriented programming; software fault injection;

    Abstract : Software implemented node level fault tolerance is an important technique for meeting dependability requirements in embedded safety critical systems. This thesis deals with both the issues of implementing mechanisms for fault tolerance and their validation. READ MORE

  5. 18. Timing Predictability in Future Multi-Core Avionics Systems

    Author : Andreas Löfwenmark; Simin Nadjm-Tehrani; Risat Pathan; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Timing Predictability; WCET; WCRT; Fault Tolerance; Safety Critical; Avionics;

    Abstract : With more functionality added to safety-critical avionics systems, new platforms are required to offer the computational capacity needed. Multi-core platforms offer a potential that is now being explored, but they pose significant challenges with respect to predictability due to shared resources (such as memory) being accessed from several cores in parallel.

  6. 19. Hierarchical scheduling for predictable execution of real-time software components and legacy systems

    Author : Rafia Inam; Mikael Sjödin; Jukka Mäki-Turja; Moris Behnam; Giuseppe Lipari; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; real-time systems; component integration and reuse; hierarchical scheduling; multicore; Computer Science; datavetenskap;

    Abstract : This dissertation presents techniques to achieve predictable execution of coarse-grained software components and for preservation of temporal properties of components during their integration and reuse.The dissertation presents a novel concept runnable virtual node (RVN) which interaction with the environment is bounded both by a functional and a temporal interface, and the validity of its internal temporal behaviour is preserved when integrated with other components or when reused in a new environment.

  7. 20. Embedded high-resolution stereo-vision of high frame-rate and low latency through FPGA-acceleration

    Author : Carl Ahlberg; Mikael Ekström; Ignacio Bravo Munoz; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer vision; stereo vision; FPGA; embedded systems; Computer Science; datavetenskap;

    Abstract : Autonomous agents rely on information from the surrounding environment to act upon. In the array of sensors available, the image sensor is perhaps the most versatile, allowing for detection of colour, size, shape, and depth. For the latter, in a dynamic environment, assuming no a priori knowledge, stereo vision is a commonly adopted technique. READ MORE
