Configurable Power Supplies For Dynamic Current Sharing

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 voltage regulator of a power supply through a first switch circuit to at least some of a plurality of cores, and distributing second power received from a second voltage regulator of the power supply through a second switch circuit to the at least some of the plurality of cores;
• responsive to a change in a first activity level associated with a first core of the plurality of cores, redistributing the first power and the second power between the at least some of the plurality of cores;
• and
• initiating a change of an output voltage of one or more of the first and second voltage regulators, responsive to the change in the first activity level exceeding an activity change threshold.

A system comprising:

• a processor comprising:
• a plurality of cores;
• a plurality of linear regulators each to receive power from a power supply coupled to the processor and output a voltage;
• a plurality of switch circuits to receive the voltage from at least one of the plurality of linear regulators;
• and
• a power controller to:
• allocate the power to the plurality of cores via the plurality of switch circuits and the plurality of linear regulators, wherein at least one of the plurality of cores is to receive a portion of the power from at least two of the plurality of linear regulators;
• receive an indication of an activity level from the at least one core;
• and
• in response to a change in the activity level of the at least one core, dynamically reallocate the power to the plurality of cores via update to control information of at least one of the plurality of switch circuits and at least one of the plurality of linear regulators;
• the power supply coupled to the processor;
• and
• a system memory coupled to the processor.
