  1. 6. 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.

  3. 7. Dynamic Management of Multi-Core Processor Resources to Improve Energy Efficiency under Quality-of-Service Constraints

    Författare :Mehrzad Nejat; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cache Partitioning; Dynamic Voltage-Frequency Scaling DVFS ; Energy Efficiency; Re-configurable Core Architecture; Multi-core Resource Management; Quality-of-Service QoS ;

    Sammanfattning : With the current technology trends, the number of computers and computation demand is increasing dramatically. In addition to different economic and environmental costs at a large scale, the operational time of battery-powered devices is dependent on how efficiently the computer processors consume energy.

  4. 8. Characterization of Shared Resource Contention in Multi-core Systems

    Författare :Jakob Danielsson; Mikael Sjödin; Stefano Di Carlo; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

    Sammanfattning : Multi-core computers are infamous for being hard to use in time-critical systems due to execution-time variations as an effect of shared resource contention. In this thesis we study the problem of shared resource contention which occurs when multiple applications executing on different cores do not have exclusive ownership of a shared resource. LÄS MER

  5. 9. Partitioned Scheduling of Real-Time Tasks on Multi-core Platforms

    Författare :Farhang Nemati; Thomas Nolte; Christer Norström; Anders Wall; Isabelle Puaut; Mälardalens högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer engineering; Datorteknik; Software engineering; Programvaruteknik; Computer Science; datavetenskap;

    Sammanfattning : In recent years multiprocessor architectures have become mainstream, and multi-core processors are found in products ranging from small portable cell phones to large computer servers. In parallel, research on real-time systems has mainly focused on traditional single-core processors. LÄS MER

  7. 10. Efficient and Flexible Embedded Systems and Datapath Components

    Författare :Magnus Själander; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Flexible; Twin-Precision; Scheduling; Embedded; Multiplier; Multi-Core;

    Sammanfattning : The comfort of our daily lives has come to rely on a vast number of embedded systems, such as mobile phones, anti-spin systems for cars, and high-definition video. To improve the end-user experience at often stringent require-ments, in terms of high performance, low power dissipation, and low cost, makes these systems complex and nontrivial to design. LÄS MER
