PROJECT TITLE :

Implementing Minimum-Energy-Point Systems With Adaptive Logic - 2016

ABSTRACT:

Timing-error-detection (TED)-based systems have been shown to cut back power consumption or increase yield because of reduced margins. This paper shows that the increased adaptability can be a great advantage in the system design additionally to the well-known mitigated susceptibility to ambient and internal variations. Specifically, the planning tolerances of the facility management are relaxed to enable even greater system-level energy savings than what will be achieved in the logic alone. In addition, the system is simultaneously ready to work close to the minimum error point. Here, the power management is a simplified dc-dc converter and therefore the TED is predicated on time borrowing. The target application may be a single-chip system on chip without external discrete parts; thus, switched capacitors are used for the dc-dc. The system achieves 7.9percent energy reduction at the minimum energy purpose simultaneously with a 36.4percent energy-delay product decrease and a fifteenp.c increase in dc-dc potency. In addition, the effect of local variations on average system performance is reduced by 12percent.
