  1. 1. On the Effects of Soft Errors in Embedded Control Systems

    Författare :Jonny Vinter; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault tolerance; error recovery techniques; concurrent error detection; pre-injection analysis; embedded control systems; fault injection; soft errors; dependable software;

    Sammanfattning : This thesis investigates techniques for making closed loop control systems fault-tolerant and robust with respect to soft errors occurring in the computer hardware. Soft errors are caused by transient faults that alter the binary values stored in latches, flip-flops and other state elements without causing any permanent damage to the hardware. LÄS MER

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

    Författare :Behrooz Sangchoolie; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault Injection; bit-flip errors; error sensitivity; soft errors; efficiency;

    Sammanfattning : 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. LÄS MER

  4. 3. Background radiation and soft errors in CMOS circuits

    Författare :Peter Hazucha; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Background radiation in natural environments from ground level to airplane flight altitudes consists of electrons, neutrons, protons, pions, muons, and other types of particles. These particles originate either from cosmic rays or from radioactive decay. LÄS MER

  5. 4. Techniques for Tolerating Soft Errors in Brake-by-Wire Systems

    Författare :Daniel Skarin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis addresses the problem of tolerating soft errors in brake-by-wire systems. Soft errors are caused by ionizing particles and manifest themselves as bit-flips in memory registers, latches, and flip-flops. As transistors are shrunk to sustain Moore's law, the frequency of such radiation-induced faults increases. LÄS MER

  7. 5. Fault Tolerance for Real-Time Systems: Analysis and Optimization of Roll-back Recovery with Checkpointing

    Författare :Dimitar Nikolov; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soft errors; fault tolerance; real-time systems; checkpointing; reliability;

    Sammanfattning : Increasing soft error rates in recent semiconductor technologies enforce the usage of fault tolerance. While fault tolerance enables correct operation in the presence of soft errors, it usually introduces a time overhead. LÄS MER
