Abstract
In order to optimise power consumption, an electronic circuit assembly comprises clock means for switching a plurality of gate circuits, the gate circuits including a first gate circuit having a first power consumption as a function of clock frequency, and a second gate circuit performing a similar function as the first circuit and having a second power requirement as a function of frequency, and means for switching off one gate circuit and switching on the other gate circuit in dependence upon the intended frequency of operation. The circuit assembly may be an arithmetical operation circuit or a finite state machine.

An electronic circuit assembly comprising clock means for switching a plurality of gate circuits, the gate circuits including a first gate circuit having a first power consumption as a function off clock frequency, and a second gate circuit performing a similar function at the first circuit and having a second power requirement as a function of frequency, and means for switching off one gate circuit and switching on the other gate circuit in dependence upon the intended frequency of operation, wherein only one of the first or second gates is operating to provide the function at a time.
