Configurable power supplies for dynamic current sharing

摘要

An apparatus includes a distribution network that includes circuitry configured to receive first power from a first voltage source and second power from a second voltage source, and to deliver power to each of a plurality of electronic circuitry blocks (ECBs), including to deliver first ECB power to a first ECB and second ECB power to a second ECB. The first ECB power includes a first portion of the first power and a first portion of the second power. The apparatus also includes power management logic to dynamically adjust the power to be provided to each ECB. Responsive to a change in a first activity level of the first ECB, the power management logic is to change the first ECB power by adjustment of the first portion of the first power and adjustment of the first portion of the second power. Other embodiments are described and claimed.

主权项

1. A processor comprising:
a plurality of electronic circuitry blocks (ECBs), including a first ECB and a second ECB; a distribution network comprising a plurality of linear regulators each to receive power from a corresponding voltage regulator and output a voltage;
a plurality of multiplexers to receive the voltage from at least some of the plurality of linear regulators and having an adjustable output current distribution to:
provide, to the first ECB, first ECB power, and provide, to the second ECB, second ECB power, wherein the first ECB power includes a first portion of first power from a first linear regulator and a first portion of second power from a second linear regulator and the second ECB power includes a second portion of the first power and a second portion of the second power; and power management logic adapted to adjust the first ECB power responsive to a change in a first activity level associated with the first ECB and update a power license level for the first ECB, the power license level stored in a configuration register and to provide an indication of peak power to be provided to the first ECB, wherein the power management logic is to dynamically change the first ECB power by adjustment of the first portion of the first power and adjustment of the first portion of the second power and to initiate a change of a magnitude of an output voltage of one or more of the first linear regulator and the second linear regulator, responsive to the change in the first activity level exceeding an activity change threshold.
