<p>Voltage scaling has emerged as a powerful technology for addressing the power challenges that current on-chip densities pose. Razor is a voltage-scaling technology based on dynamic, in-situ detection and correction of circuit-timing errors. Razor permits design optimizations that tune theenergy in a microprocessor pipeline to typical circuit-operational levels. This eliminates the voltage margins that traditional worst-case design methodologies require and lets digital systems run correctly and robustly at the edge of minimum power consumption.</p><p>Occasional heavyweight computations may fail and require additional time and energy for recovery, but the optimized pipeline requires significantly less energy overall than traditional designs.</p>
