Summary: Abstract
Dynamic power is the main source of power
consumption in CMOS circuits. It depends on the square of
the supply voltage. It may significantly be reduced by
scaling down the supply voltage of some computational
elements in the circuit, with the penalty of an increase of
their execution delay. To reduce the dynamic power
consumption, without degrading the performance
determined assuming that the circuit operates at the highest
available supply voltage, the supply voltage of
computational elements off critical paths can be scaled
down. Defined here as MinPdyn, the problem of minimizing
the dynamic power consumption, under performance
constraints, by scaling down the supply voltage of
computational elements on non-critical paths is NP-hard in
general. Solving MinPdyn for multi-phase clocked
sequential circuits may allow to reduce their power
consumption and the required number of registers.
Reducing the number of registers also allows to reduce the
power consumption, the number of control signals, and the
