    Sammanfattning : The improvement of dependability in computing systems requires the evaluation of fault tolerance mechanisms such as error detection, error recovery and reconfiguration. Central to this thesis is an experimental evaluation of several hardware and/or software implemented mechanisms for the concurrent detection of control flow errors. LÄS MER

  5. 30. Fault Injection for Studying Error Behavior and Validation of Error Detecting Mechanisms

    Författare :Marcus Rimén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; concurrent error detection; functional error model; control flow error; error detection coverage; permanent faults; data error; error detection latency; simulation-based fault injection; transient faults; physical fault injection; dependability evaluation;

    Sammanfattning : This thesis deals with the design and validation of low-cost error detecting mechanisms that can be used to implement self-checking computers. The research objectives of the thesis are three-fold: (i) to investigate and develop a simulation-based fault injection technique that can be used on a wide range of VHDL simulation models, (ii) to investigate error propagation mechanisms in microprocessors in order to understand how to design low-cost error detecting mechanisms and (iii) to design and validate error detecting mechanisms.
