    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: Various embodiments of methods and systems for thermal energy management in a portable computing device (“PCD”) based on power level calculations are disclosed. An exemplary method includes tracking instantaneous operating temperatures and active power supply levels to one or more components. With an estimate or measurement of ambient temperature, the instantaneous operating temperature values and active power supply level values can be used to calculate an instantaneous thermal resistance value. In the event that thermal energy generation should be managed, a target operating temperature may be used with the ambient temperature and the instantaneous thermal resistance value to solve for an optimum power supply level. The active power supply level may then be adjusted based on the calculated optimum power supply level.

    Abstract: A method and system for adjusting bandwidth within a portable computing device based on danger signals monitored from one on more elements of the portable computing device are disclosed. A danger level of an unacceptable deadline miss (“UDM”) element of the portable computing device may be determined with a danger level sensor within the UDM element. Next, a quality of service (“QoS”) controller may adjust a magnitude for one or more danger levels received based on the UDM element type that generated the danger level and based on a potential fault condition type associated with the particular danger level. The danger levels received from one UDM element may be mapped to at least one of another UDM element and a non-UDM element. A quality of service policy for each UDM element and non-UDM element may be mapped in accordance with the danger levels.

    Abstract: Various embodiments of methods and systems for estimating environmental ambient temperature of a portable computing device (“PCD”) from electrical resistance measurements taken voice coils in a speaker or microphone component 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. Electrical resistance measurements are taken from a voice coil 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.
