In-situ Fmax/Vmin tracking for energy efficiency and reliability optimization

Résumé : Achieving the lowest possible operating voltage is needed to minimize the power consumption of a circuit but also to increase its reliability w.r.t hardware errors. An in-situ technique to estimate and reduce the design margins of a circuit is presented which significantly minimizes the operating voltage and tracks it during run-time operation of a circuit without failure. A DSP core embedding this technique has been fabricated and measured. Its V$_{min}$ has been estimated within +3.5%/-2.5% at nominal clock frequency (1600MHz), thus reducing by 19% its energy per operation.
