Abstract
Embodiments of a method and an apparatus for on-demand power management of a processing system have been presented. In some embodiments, the apparatus includes a power management unit (PMU) to provide power to an electronic system. The apparatus further includes a power management controller (PMC) coupled to the power management unit, to control values of one or more parameters of an operating state of the PMU in response to the operating conditions of the electronic system. The PMC may execute a power management algorithm (PMA) to determine the values of the parameters. Further, the PMU and the PMC may reside on different integrated circuit substrates.
Claims24
An apparatus comprising:
- a power management unit (PMU) to provide power to an electronic system, wherein the PMU resides on a first integrated circuit (IC) substrate;
- and
- a power management controller (PMC) residing on a second IC substrate distinct from the first IC substrate, the PMC coupled to the PMU to control values of one or more parameters of an operating state of the PMU in response to operating conditions of the electronic system, wherein the PMC is configured to execute a power management algorithm (PMA) to determine values of the one or more parameters.
A method comprising:
- providing power to an electronic system via a power management unit (PMU);
- and
- executing a power management algorithm (PMA) on a power management controller (PMC) to determine values of one or more parameters of an operating state of the PMU in response to operating conditions of the electronic system.
A machine-readable medium that provides instructions that, when executed by a power management controller (PMC), will cause the PMC to perform operations comprising:
- executing a power management algorithm (PMA) to determine values of one or more parameters of an operating state of a power management unit (PMU) in response to operating conditions of an electronic system, wherein the PMU provides power to the electronic system;
- and
- causing the PMU to enter into the operating state.
