Abstract: Systems and methods for forecasting behavior of caches include a hypothetical cache. The hypothetical cache is configured to emulate cache behavior, and performance metrics for the hypothetical cache are determined, where the performance metrics may be based on cache hits/misses. Performance metrics for a real cache of a processor core of a processing system may also be similarly determined. Behavior of the real cache is forecast based, at least, on performance metrics of the hypothetical cache, and in some cases, also on performance metrics of the real cache (e.g., based on a comparison of the performance metrics). Actions may be recommended and/or performed based on the forecast, where the actions include modifying the real cache size, associativity, or allocation for processor cores, migrating a task running in one processor cluster to another processor cluster, or for collecting data for the real cache for offline analysis.

Abstract: Systems, methods, and computer programs are disclosed for dynamically adjusting memory power state transition timers. One embodiment of a method comprises receiving one or more parameters impacting usage or performance of a memory device coupled to a processor in a computing device. An optimal value is determined for one or more memory power state transition timer settings. A current value is updated for the memory power state transition timer settings with the optimal value.

Abstract: Various embodiments of methods and systems for energy efficiency aware thermal management in a portable computing device that contains a heterogeneous, multi-processor system on a chip (“SoC”) are disclosed. Because individual processing components in a heterogeneous, multi-processor SoC may exhibit different processing efficiencies at a given temperature, energy efficiency aware thermal management techniques that compare performance data of the individual processing components at their measured operating temperatures can be leveraged to optimize quality of service (“QoS”) by adjusting the power supplies to, reallocating workloads away from, or transitioning the power mode of, the least energy efficient processing components. In these ways, embodiments of the solution optimize the average amount of power consumed across the SoC to process a MIPS of workload.

Abstract: In an example, a method includes determining, by an electronic device, a user experience metric associated with content captured by at least one camera of the electronic device. The method also includes adjusting at least one operating parameter of the device to produce an operating characteristic target, wherein the adjustment is based on an estimated change to the determined user experience metric due to the adjustment.
