Universal Rules Guided Design Parameter Selection for Soft Error Resilient Processors

High-performance processors suffer from soft error vulnerability due to the increasing on-chip transistor density, shrinking processor feature size, lower threshold voltage, etc. In this paper, the authors propose to use a rule search strategy, i.e. Patient Rule Induction Method (PRIM), to optimize processor soft error robustness. By exploring a huge micro-architectural design space on the Architectural Vulnerability Factor (AVF), they are capable of generating a set of selective rules on key design parameters. Applying these rules at early design stage effectively identifies the configurations that are inherently reliable to soft errors.
