1. A system comprising:
- an integrated circuit;
a plurality of power islands of the integrated circuit having associated power consumptions, each of the power consumptions adapted to be independently controlled; and
a power manager to control the power consumptions;
at least one of the power islands adapted to have the power manager control its associated power consumption by a) the at least one of the power islands being configured to have one of plural threshold voltages of variable threshold transistors selected, and b) the system being configured to perform, during operation, an action on the at least one of the power islands, the action including changing a frequency of operation or changing a supply voltage.

Abstract
A system for an integrated circuit comprising a plurality of power islands includes a first power manager and a second power manager. The first power manager manages a first power consumption for the integrated circuit based on needs and operation of the integrated circuit. The second power manager communicates with the first power manager and manages a second power consumption for one of the power islands.

24. A processor implemented method comprising:
-
employing a power manager processor within an integrated circuit to control power consumptions of a plurality of power islands of the integrated circuit, each having an associated power consumption, each of the power consumptions being independently controlled; and controlling the power consumption of at least one of the power islands by;
a) selecting a threshold voltage of variable threshold transistors, and b) changing during operation at least one of the following;
i) a frequency of operation, and ii) a supply voltage. - View Dependent Claims (25, 26, 27, 28, 29)
