DCFirst Claim
Patent Images
1. An integrated circuit comprising:
- an integrated circuit chip;
a plurality of power islands disposed on the integrated circuit chip having associated power consumptions, each of the power consumptions being independently controllable by changing a supply voltage and operating frequency;
one or more power consumption signals indicating one or more of the power consumptions;
a power management processor disposed on the integrated circuit chip and coupled to each of the power islands configured to monitor the one or more power consumption signals, the power management processor being dedicated to execute power management software to individually control each of the power consumptions, and the power management processor being configured to change power consumption in at least one of the power islands in response to a power consumption change request.

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.
