Is Power the New Brick Wall?
Abstract
Classical CMOs has still life left. Fully depleted devices will offer additional knobs for gate length scaling. Careful analysis of power delivery and I/Os show opportunities to reduce power losses in the system. Low voltage operation is biggest knob for power reduction, however need massive parallelism to get performance back and watch out for a low voltage cache situation. Sleep sub-threshold devices have their place in the low power applications, Need to push devices to obtain at lest 10% on current as conventional device. Adiabatic computing: the concepts are there, not clear where application space is. This needs further research.
