Abstract: Various embodiments of methods and systems for estimating environmental ambient temperature of a portable computing device (“PCD”) from temperature measurements taken within the PCD are disclosed. In an exemplary embodiment, it may be recognized that the PCD is in an idle state, thus producing little or no thermal energy. Temperature measurements are then taken from temperature sensors within the PCD and used to estimate the environmental ambient temperature to which the PCD is exposed. Certain embodiments may simply render the estimated ambient temperature for the benefit of the user or use the estimated ambient temperature as an input to a program or application running on the PCD. It is envisioned that certain embodiments of the systems and methods may use the estimated ambient temperature to adjust temperature thresholds in the PCD against which thermal management policies govern thermally aggressive processing components.

Abstract: Various embodiments of methods and systems for idle state optimization in a portable computing device (“PCD”) are disclosed. An exemplary method includes comparing an aggregate power consumption level for all processing cores in the PCD to a power budget and, if there is available headroom in the power budget, transitioning cores operating in a first idle state to a different idle state. In doing so, the latency value associated with bringing the transitioned cores out of an idle state and into an active state, should the need arise, may be reduced. The result is that user experience and QoS may be improved as an otherwise idle core in an idle state with a long latency time may be better positioned to quickly transition to an active state and process a workload.

Abstract: A method and system for managing a thermal policy of a receiving device that couples to a portable computing device (PCD) includes automatically detecting a presence of the PCD. After detecting the presence of the PCD, a command to deactivate a thermal sensor and to deactivate a power supply within the PCD may be issued. The thermal policy manager module of the receiving device may issue a command to adjust an operating condition of a processor within the PCD if a temperature value reaches a predetermined value. The thermal policy manager module may also adjust operation of an active cooling device if the temperature value sensed by a sensor within the PCD reaches a predetermined value. The receiving device may include at least one of a docking station, a tablet personal computer, a laptop personal computer, a desktop personal computer, a portable media player, a portable television, and a printer.
