Abstract: A method and apparatus for providing proactive current protection. In one embodiment, the method comprises: prior to transitioning to a new state for an integrated circuit (IC), calculating a sum of expected powers for a plurality of domains in the IC by calculating an expected current for each of the plurality of domains based on an individual domain frequency in the new state and multiplying the expected current with its associated voltage for each of the plurality of domains for the new state; comparing the sum to a power limit; and if the sum is greater than the power limit, then reducing the individual domain frequency associated with at least one domain in the plurality of domains to maintain the total instantaneous power of the IC below the power limit.

Abstract: Techniques and mechanisms for transparently transitioning an interconnect fabric between a first frequency and a second frequency. In an embodiment, the fabric is coupled to an end point device via an asynchronous device. One or more nodes of the fabric operate in a first clock domain based on a clock signal, while the end point device operates in a different clock domain. Controller circuitry changes a frequency of the clock signal by stalling the clock signal throughout a first period of time which is greater than a duration of three cycles of a lower one of the first frequency or the second frequency. After the first period of time, cycling of the clock signal is provided at the second frequency. In another embodiment, the asynchronous device enables the frequency change without preventing communication with the end point device.

In response to the preliminary frequency for the selected core being greater than the dynamic tuning frequency for that core, the power management control logic is to set the core to a frequency that is at least equal to the preliminary frequency.
