  1. 1. On Efficient Measurement of the Impact of Hardware Errors in Computer Systems

    Author : Behrooz Sangchoolie; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fault Injection; bit-flip errors; error sensitivity; soft errors; efficiency;

    Abstract : Technology and voltage scaling is making integrated circuits increasingly susceptible to failures caused by soft errors. The source of soft errors are temporary hardware faults that alter data and signals in digital circuits. READ MORE

  2. 2. Measuring the Impact of Hardware Errors in Computer Systems

    Author : Behrooz Sangchoolie; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sources of Variation; Fault Injection; Dependability Assessment; Microprocessor Faults; Hardware Error Sensitivity;

    Abstract : This thesis addresses the problem of measuring hardware error sensitivity of computer systems. Hardware error sensitivity is the probability that a hardware error will result in an erroneous output. READ MORE

  3. 3. On Concurrent Error Detection and Error Propagation

    Author : Joakim Ohlsson; Chalmers University of Technology; []
    Keywords : error models; control flow monitoring; simulation experiments; concurrent error detection; permanent faults; watchdog processors; fault injection; transient faults;

    Abstract : This thesis addresses three important steps in the selection of error detection mechanisms for microprocessors: (i) the design and evaluation of error detection mechanisms, (ii) the study of microprocessor error behavior and propagation and (iii) the design and use of error models. The first part of the thesis evaluates four error detection methods with respect to para- meters such as error detection coverage and performance loss, while the second and third parts focus on determining the error patterns most likely to occur in a computer system when different types of faults are present and how to incorporate those error patterns into error models.

  4. 4. Quantum error correction

    Author : Jonas Almlöf; Gunnar Björk; Jan-Åke Larsson; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; quantum error correction; dissipative channel; decoherence; fidelity; mutual information;

    Abstract : This thesis intends to familiarise the reader with quantum error correction, and also show some relations to the well known concept of information - and the lesser known quantum information. Quantum information describes how information can be carried by quantum states, and how interaction with other systems give rise to a full set of quantum phenomena, many of which have no correspondence in classical information theory.
