Transient Error Recovery Techniques for Pipelines and Memory Systems

This thesis presents fundamental results related to the problem of system recovery from transient errors. Scrubbing methods are suggested for memory systems and retry techniques are discussed for pipelines. A probabilistic model for the activity of faulty periods is introduced, and a fault analysis is carried out to decide the optimum length of the retry period, T. Distribution functions are derived to represent the case of false alert, where a transient fault is flagged as permanent, and the case of a miss, where too many errors coexist, thus overcoming the checker's capability to detect them. These derivations are compared with the results of a simulation program representing the model used.
