CONFIGURABLE POWER SUPPLIES FOR DYNAMIC CURRENT SHARING
First Claim
1. An apparatus comprising:
- a distribution network comprising circuitry configured to;
receive first power from a first source and second power from a second source; and
provide, to a first electronic circuitry block (ECB), first ECB power, and provide, to a second ECB, second ECB power, wherein the first ECB power includes a first portion of the first power and a first portion of the second power 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 configured to adjust the first ECB power responsive to a change in a first activity level associated with 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.

Abstract
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.

13. A machine-readable medium having stored thereon instructions, which if performed by a machine cause the machine to perform a method comprising:
-
distributing first power received from a first source to each of a plurality of electronic circuitry blocks (ECBs) of a system on a chip (SOC), and distributing second power received from a second source to each of the plurality of ECBs; and responsive to a change in a first activity level associated with a first ECB of the plurality of ECBs, redistributing the first power and the second power among the plurality of ECBs. - View Dependent Claims (14, 15, 16, 17)

18. A system comprising:
-
power management logic to; allocate power provided by a plurality of power sources to each of a plurality of electronic circuitry blocks (ECBs), wherein each of the plurality of power sources is to provide a respective portion of the power that is allocated among two or more of the ECBs; receive an indication of a corresponding activity level from each of at least one of the plurality of ECBs; responsive to a change in the activity level of one of the ECBs, dynamically reallocate the power to the plurality of ECBs; and memory to store configuration information for each ECB. - View Dependent Claims (19, 20)
