Abstract: In an embodiment, a processor includes a plurality of cores and a plurality of temperature sensors, where each core is proximate to at least one temperature sensor. The processor also includes a power control unit (PCU) including temperature logic to receive temperature data that includes a corresponding temperature value from each of the temperature sensors. Responsive to an indication that a highest temperature value of the temperature data exceeds a threshold, the temperature logic is to adjust a plurality of domain frequencies according to a determined policy that is based on instruction execution characteristics of at least two of the plurality of cores. Each domain frequency is associated with a corresponding domain that includes at least one of the plurality of cores and each domain frequency is independently adjustable. Other embodiments are described and claimed.

Abstract: A method and apparatus for providing power state information using in-band signaling are described. In one embodiment, an integrated circuit (IC) device comprises a controller operable to receive a command from a platform control bus, the command requesting data that is unrelated to information about a power state in which the IC resides; and control logic operable to obtain data for inclusion in a response to the command, wherein the controller is operable to send the response over a bus, the response containing at least a portion of the data responsive to the command and containing power state information for the IC.

Abstract: Examples are disclosed for an integrated circuit (IC) device coupled to a battery-operated power supply unit, such as an IC in a mobile computing device or wireless phone, to accurately determine energy usage drawn from the power supply unit under rapidly dynamic circumstances. A current sense signal of a power line from the power supply unit is digitized. The digitized current sense is added to an accumulator at a rate that is approximately proportional to a voltage of the power line from the power supply unit. The accumulator is then outputted and scaled to units relevant to energy measurements. The energy measurement is used to estimate remaining battery life. Triggering the digitization of the current sense signal may be by use of a pulse generation circuit, or by use of an overflow indicator of an accumulator for a digitized voltage sense signal.

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.
