Abstract (en)
[origin: WO2009115744A2] The method relates to a device for powering an electronic circuit (10) able to apply at least a first voltage (Vhigh) or a second voltage (Vlow)different from the first voltage to the electronic circuit. This device comprises in particular a performance monitor (22) able to receive an item of information defining a constraint (C) and to determine a first duration and a second duration which are such that the operation of the circuit at a first frequency (Fhigh) associated with the first voltage (Vhigh) for the first duration and at a second frequency (Flow) associated with the second voltage (Vlow) for the second duration complies with said constraint (C). The device applies (24, 20, 14) to the circuit (10) the first voltage (Vhigh) and the first frequency (Fhigh) for the first duration and the second voltage (Vlow) and the second frequency (Flow) for the second duration.
