ABSTRACT:
A power control circuit and corresponding technique for controlling the reduction or augmentation of operating frequency and/or supply voltage utilized by an electronic device. Such control is based on the operating environment of the hardware product employing the electronic device by determining whether the hardware product is interconnected to an external source having at least one enhanced cooling mechanism. As a result, the hardware product is able to operate at full frequency and voltage during certain situations and to operate at a reduced frequency and/or voltage during other situations.
