In accordance with some embodiments, margining routines to determine acceptable voltage command values for specific CPU implementations at one or more different operating levels may be provided.

Supply margining Method and apparatus

Supply margining method and apparatus

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.

Supply voltage control based at least in part on power state of integrated circuit

For one disclosed embodiment, switching voltage regulator circuitry may be controlled to supply a voltage to at least a portion of an integrated circuit. Information corresponding to a current load for a different power state of at least a portion of the integrated circuit may be received. The switching voltage regulator circuitry may be controlled to adjust the voltage to a different value based at least in part on the received information. For another disclosed embodiment, a voltage may be received for a power state of at least a portion of an integrated circuit 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 integrated circuit may be sent from the second logic to voltage regulator control logic to adjust the voltage to a different value. Other embodiments are also disclosed.
