POWER MANAGERS FOR AN INTEGRATED CIRCUIT
First Claim
Patent Images
1. A method of managing power on an integrated circuit including a plurality of power islands, the method comprising:
- determining a target power level for one of the power islands where power consumption is independently controlled within each of the power islands;
determining an action to change a consumption power level of the one of the power islands to the target power level; and
performing the action to change the consumption power level of the one of the power islands to the target power level.

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.

17. A system for an integrated circuit comprising a plurality of power islands where power consumption is independently controlled within each of the power islands, the system comprising:
-
power control circuitry configured to control power for one of the power islands; and a power manager configured to determine a target power level for one of the power islands, determine an action to change a consumption power level of the one of the power islands to the target power level, and perform the action to change the consumption power level of the one of the power islands to the target power level. - View Dependent Claims (18, 19, 20)
