  2. 1. On Impact and Tolerance of Data Errors with Varied Duration in Microprocessors

    Author : Örjan Askerdal; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fault injection; dependability; error propagation analysis; fault tolerance; error effect analysis;

    Abstract : The evolution of high-performance and low-cost microprocessors has led to their almost pervasive usage in embedded systems such as automotive electronics, smart gadgets, communication devices, etc. These mass-market products, when deployed in safety-critical systems, require safe services albeit at low recurring costs.

  4. 2. Reconfigurable NoC and Processors Tolerant to Permanent Faults

    Author : Alirad Malek; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networks-on-Chip; Fault Tolerance; Permanent Faults; Reconfigurable Hardware; Adaptive processors;

    Abstract : Advances in semiconductor industry have led to reduced transistor dimensions andincreased device density, but inevitably they have compromised the reliability of moderncomputing systems. In this thesis, we address the reliability problemby exploitinghardware reconfiguration for tolerating permanent faults. READ MORE

  5. 3. Advances on Adaptive Fault-Tolerant System Components: Micro-processors, NoCs, and DRAM

    Author : Alirad Malek; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network-on-Chip; Quality-of-Service; Main memory; Micro-processors; Error-Correcting Codes; Reliability analysis; Adaptive fault tolerance;

    Abstract : The adverse effects of technology scaling on reliability of digital circuits have made the use of fault tolerance techniques more necessary in modern computing systems. Digital designers continuously search for efficient techniques to improve reliability, while keeping the imposed overheads low. READ MORE

  6. 4. 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.

  7. 5. Theoretical Aspects on Performance Bounds and Fault Tolerance in Parallel Computing

    Author : Kamilla Klonowska; Blekinge Institute of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis consists of two parts: performance bounds for scheduling algorithms for parallel programs in multiprocessor systems, and recovery schemes for fault tolerant distributed systems when one or more computers go down. In the first part we deliver tight bounds on the ratio for the minimal completion time of a parallel program executed in a parallel system in two scenarios. READ MORE
