A more direct power management architecture may be provided using integrated voltage regulators and in some embodiments, a direct power management interface (DPMI) as well. Integrated voltage regulators, such as in-silicon voltage regulators (ISVR) can be used to implement quicker, more highly responsive power state transitions.

Embodiments of an apparatus, system and method are described for dynamically time-interleaving supply voltage modulation to shape a power profile. An apparatus may comprise, for example, a power management module to monitor power information received from a plurality of devices and send a power control signal including delay information to each device having power information that exceeds a power threshold, the delay information comprising information for time-interleaving power usage among the devices having power information that exceeds the power threshold. Other embodiments are described and claimed.

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.

Techniques to enable voltage regulators to adjust for coming load changes are presented herein. In some embodiments, a functional block such as a microprocessor core having an associated clock signal is powered by at least one switching-type voltage regulator. When the functional block is about to require an increased level of power, the associated clock is provided to drive the at least one regulator switches overriding their normal drive signal, which has a lower frequency. Thus, the switches are driven at a higher frequency sufficiently prior to (e.g., just ahead of) the load change to reduce the amount of droop that would otherwise occur.
