Abstract
Power regulator circuitry that can provide a regulated power signal. The power regulator circuitry may include data processing circuitry configured to determine the regulated power signal to arbitrate power supply requirements of first and second powered devices according to power supply information associated with the first and second powered devices. The power regulator circuitry may also include output circuitry configured to output the regulated power signal to one or both of the first and second powered devices.
Claims20
Power regulator circuitry, comprising:
- communication interface circuitry configured to receive power supply information, the power supply information including power source information associated with a plurality of power sources external to the power regulator circuitry;
- data processing circuitry configured to determine a regulated power signal to arbitrate power supply requirements of first and second powered devices according to the power supply information and a weighted averaged load between the first and second powered devices based on priority information of the first and second powered devices, the power supply information also including powered device information associated with the first and second powered devices;
- and
- output circuitry configured to output the regulated power signal to one or both of the first and second powered devices.
A method, comprising:
- receiving, at power management circuitry, a plurality of respective power signals from a plurality of power supply devices external to the power management circuitry;
- receiving, at the power management circuitry, power supply information, the power supply information including power source information associated with the plurality of power supply devices;
- and
- arbitrating, by the power management circuitry, the plurality of respective power signals between a plurality of powered devices according to the power supply information and a weighted averaged load between the plurality of powered devices, the weighted averaged load based on priority information of the plurality of powered devices, and the power supply information also including powered device information associated with the plurality of powered devices.
Power management circuitry, comprising:
- communication circuitry configured to receive power supply information from a plurality of powered devices and a plurality of power supply devices, wherein the power supply information includes information associated with electrical power supplied from the plurality of power supply devices and power requirements of the plurality of powered devices;
- and
- power regulator circuitry configured to:
- determine a regulated power signal associated with the supplied electrical power according to the power supply information and a weighted averaged load between the plurality of powered devices based on priority information of the plurality of powered devices;
- and
- arbitrate the regulated power signal between the plurality of powered devices according to the power supply information.
