Abstract :
An ARM ISA processor fabricated in a 65nm CMOS process uses a combination of timing-error detecting circuits and micro-architectural recovery mechanisms to eliminate safety guardbands. Measurements performed on a distribution of 63 samples, including split lots, show a 52% power reduction for the overall distribution, for 1GHz operation.
