SUPPLY VOLTAGE CONTROL BASED AT LEAST IN PART ON POWER STATE OF INTEGRATED CIRCUIT

摘要

Disclosed is a switching voltage regulator circuitry controlled to supply a voltage to at least a portion of an integrated circuit (IC). Information corresponding to a current load for a different power state of at least a portion of the IC is received. The switching voltage regulator circuitry is controlled to adjust the voltage to a different value based at least in part on the received information. Disclosed is a voltage received for a power state of at least a portion of an IC having first logic to perform one or more functions and second logic integrated with the first logic. Information corresponding to a current load for a different power state of at least a portion of the IC is sent from the second logic to voltage regulator control logic to adjust the voltage to a different value.
