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: Systems and methods are provided for allocating memory to dissimilar memory devices. An exemplary embodiment includes a method for allocating memory to dissimilar memory devices. An interleave bandwidth ratio is determined, which comprises a ratio of bandwidths for two or more dissimilar memory devices. The dissimilar memory devices are interleaved according to the interleave bandwidth ratio to define two or more memory zones having different performance levels. Memory address requests are allocated to the memory zones based on a quality of service (QoS).

Abstract: Systems and methods are provided for dynamically allocating a memory subsystem. An exemplary embodiment comprises a method for dynamically allocating a memory subsystem in a portable computing device. The method involves fully interleaving a first portion of a memory subsystem having memory components with asymmetric memory capacities. A second remaining portion of the memory subsystem is partial interleaved according to an interleave bandwidth ratio. The first portion of the memory subsystem is allocated to one or more high-performance memory clients. The second remaining portion is allocated to one or more relatively lower-performance memory clients.

Abstract: Various embodiments of methods and systems for tuning a thermal strategy of a portable computing device (“PCD”) based on PCD location information. In an exemplary embodiment, it may be recognized that the PCD is in an active state and producing thermal energy, or that one or more thermally aggressive components of the PCD are operating near temperature thresholds for efficient operation. The PCD location information is 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 may use the estimated ambient temperature as an input to a program, application, or algorithm 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 PCD components.
