ABSTRACT:
A method and an apparatus for controlling voltage level and clock signal frequency supplied to a system. The apparatus includes a hardware module, adapted to receive at least one indication of a load of the system and to determine a voltage level and a clock signal frequency to be provided to the system, and a software module, adapted to configure a voltage source and a clock signal source in response to the determination. The method includes: (i) receiving, at a hardware module, indication of a load of a system; (ii) determining, by the hardware module, a voltage level and a clock signal frequency to be provided to the system; and (iii) configuring, by a software module, a voltage source and a clock signal source in response to the determination.
