In this paper, we present a novel technique for early prediction of timing violations in high-performance pipelined microprocessors. We show that a static instruction in a microprocessor, identified by its Program Counter (PC), is an excellent predictor of an upcoming timing violation. Our analysis combines architectural data collected from real program execution with gate level logic analysis. Exploiting this PC based timing violation predictability, we propose a robust system design that predicts and tolerates timing violations seamlessly in a pipelined microprocessor. Under two different faulty environments, we show 20.9-89.8% and 14.6-80.6% average performance improvements in real programs over other state-of-the-art techniques, respectively. © 2012 ACM.
