ABSTRACT:
The present invention provides for controlling the power consumption of an element. A first power control command is issued by software for the element. It is determined if the power control command corresponds to an allowable power control state for that element as defined by the hardware. If the power control command is not an allowable power control state for that element, the hardware sets the power control at a higher level than the power control state issued by the software. A hierarchy of power consumption is defined for different elements of a chip by software, which provides the minimum level of power consumption by any element or sub-element on a chip.
