    Abstract: An apparatus and method for temperature-constrained frequency control and scheduling. For example, one embodiment of a processor comprises: a plurality of cores; power management circuitry to control a frequency of each core of the plurality of cores based, at least in part, on a temperature associated with one or more cores of the plurality of cores, the power management circuitry comprising: a temperature limit-driven frequency controller to determine a first frequency limit value based on a temperature of a corresponding core reaching a first threshold; frequency prediction hardware logic to predict a temperature-constrained frequency of the corresponding core based on the first frequency limit value and an initial frequency limit value; and performance determination hardware logic to determine a new performance value for the corresponding core based on the temperature-constrained frequency, the new performance value to be provided to a task scheduler.

    Abstract: Methods and apparatus for in-field thermal calibration are disclosed. A disclosed example apparatus includes instructions, memory in the apparatus, and processor circuitry. The processor circuitry is to execute the instructions to determine that a system on chip (SOC) package is deployed, the SOC package deployed with a default first thermal model, in response to the determination that the SOC package is deployed, monitor at least one temperature of the SOC package from a sensor and power usage of the SOC package, calibrate a second thermal model based on the at least one temperature and the power usage, and publish the calibrated second thermal model for control of the SOC package.

    Abstract: Enhanced thermal energy transfer systems for semiconductor packages are provided. A thermally conductive member is disposed in the interstitial space between an upper surface of a semiconductor package and a lower surface of a thermal member. The thermally conductive member is disposed above a first portion of the upper surface of the semiconductor package having a relatively higher thermal energy output when the semiconductor package is operating. A thermal interface material is disposed in the interstitial space and a force applied to the thermal member. The thermally conductive member forms a relatively higher pressure region above the first portion of the semiconductor package and a relatively lower pressure region in other portions of the semiconductor package remote from the thermally conductive member. The increased pressure region proximate the thermally conductive member beneficially enhances the flow of thermal energy from the first portion of the semiconductor package to the thermal member.

    Abstract: Mobile platforms and methods may provide for an integrated circuit such as a system on chip (SoC), a first heat spreader thermally coupled to the integrated circuit and a phase change material configuration thermally coupled to the first heat spreader. The integrated circuit may include logic to operate the integrated circuit in a performance burst mode according to a duty cycle, wherein the performance burst mode causes a phase change material to enter a liquid state within a graphite matrix of the phase change material configuration.
