  1. 26. Timing Predictability in Future Multi-Core Avionics Systems

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

    Sammanfattning : 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.

    Sammanfattning : This thesis discusses modeling and implementation of reconfigurable hardware architectures for real-time applications. The target application in this work is digital holographic imaging, where visible images are to be reconstructed based on holographic recordings. LÄS MER

  5. 29. On particle-based online smoothing and parameter inference in general hidden Markov models

    Författare :Johan Westerborn; Jimmy Olsson; Thomas Schön; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis consists of two papers studying online inference in general hidden Markov models using sequential Monte Carlo methods.The first paper present an novel algorithm, the particle-based, rapid incremental smoother (PaRIS), aimed at efficiently perform online approximation of smoothed expectations of additive state functionals in general hidden Markov models.

  7. 30. Efficient parallell architectures for future radar signal processing

    Författare :Anders Åhlander; John L. Gustafson; Högskolan i Halmstad; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
