Title
Trade-off analysis between timing error rate and power dissipation for adaptive speed control with timing error prediction
Abstract
Timing margin of a chip varies chip by chip due to manufacturing variability, and depends on operating environ- ment and aging. Adaptive speed control with timing error predic- tion is a promising approach to mitigate the timing margin vari- ation, whereas it inherently has a critical risk of timing error oc- currence when a circuit is slowed down. This paper presents how to evaluate the relation between timing error rate and power dis- sipation in self-adaptive circuits with timing error prediction. The discussion is experimentally validated using a 32-bit ripple carry adder in subthreshold operation in a 90nm CMOS process. We show a trade-off between timing error rate and power dissipation, and reveal the dependency of the trade-off on design parameters.
