Abstract: Disclosed are methods and systems for intelligent adjustment of an immersive multimedia workload in a portable computing device (“PCD”), such as a virtual reality (“VR”) or augmented reality (“AR”) workload. An exemplary embodiment monitors one or more performance indicators comprising a motion to photon latency associated with the immersive multimedia workload. Performance parameters associated with thermally aggressive processing components are adjusted to reduce demand for power while ensuring that the motion to photon latency is and/or remains optimized. Performance parameters that may be adjusted include, but are not limited to including, eye buffer resolution, eye buffer MSAA, timewarp CAC, eye buffer FPS, display FPS, timewarp output resolution, textures LOD, 6DOF camera FPS, and fovea size.

Abstract: Various embodiments include power management system methods including receiving, at a processor(s), a notification signal triggering the processor(s) to implement power usage mitigation at the processor(s), determining, by the processor(s), a mitigation amount of power rail power by which to mitigate current usage at a power rail based on a use case for the power rail, and implementing power usage mitigation at the processor(s) by the processor(s) sufficient to mitigate power usage at the power rail by the mitigation amount of power rail power. Power usage mitigation may include reducing processor(s) current usage: by a predefined amount; proportional to the amount a power rail current exceeds a power rail current threshold; by the amount of current exceeding a processor current threshold; or by a smallest amount between the amount a power rail current exceeds a power rail current threshold and the processor(s) current exceeds a processor current threshold.

Abstract: Power monitoring and limiting of processing units in a processor-based system to limit the overall power consumption of the processor-based system. In exemplary aspects, to limit the overall power consumption of the processor-based system while attempting to achieve an optimized performance of all the processing units, an overall power limit budget is allocated for the processing units (“processing unit power limit budget”). The processor-based system is configured to dynamically determine a total processing unit power limit budget available for the processing units based on remaining overall power available not consumed by other power consuming circuits. The processor-based system is configured to allocate the total processing unit power limit budget for processing units, that is then allocated to the different processing units based on their variances in workloads to try to achieve an optimal performance of the processing units while keeping the processor-based system within its overall power consumption limit.

Abstract: Various aspects of the present disclosure include methods, components and wireless devices configured to determine appropriate generalized system-wide thermal management policies and settings in wireless devices depending upon whether communication activities are driving or otherwise causing thermal conditions. In various aspects, a processor may determine workload characteristics and select and apply an appropriate thermal management policy/solution (or thermal configuration, settings etc.) based on the determine workload characteristics. The processor may determine workload characteristics based upon data from two or more temperature sensors within the wireless device. The processor may select a generalized system-wide thermal management policy suitable for operating when communication activities (e.g., 5G communication activities) are generating so much heat that CPU-centric thermal management policies are in appropriate.

Abstract: Power limiting in a processor-based system based on allocating power budgets for different sub-systems based on multiple time-based power limits is disclosed. The processor-based system has multiple power consuming sub-systems (e.g., non-processing unit (PU) and PU sub-systems) that demand and consume power from a power source of the processor-based system. To limit overall power consumption of the processor-based system over different time-based power limits, the processor-based system includes a power limiter circuit. The power limiter circuit is configured to manage multiple, different time-based (e.g., time constant) power limits for the processor-based system and to allocate corresponding power limit budgets to constrain power consumption of different sub-systems based on the multiple time-based power limits. The power limiter circuit can be configured to constrain power consumption of a PU sub-system to a total PU sub-system power limit budget based on the multiple time-based power limits.

Abstract: Various embodiments of methods and systems context-aware thermal management in a portable computing device (“PCD”) are disclosed. Notably, the environmental context to which a PCD is subjected may have significant impact on the PCD's thermal energy dissipation efficiency. Embodiments of the solution seek to leverage knowledge of a PCD's environmental context to modify or adjust thermal policy parameters applied within a PCD in response to a thermal event within the PCD.

The apparatus prioritizes the plurality of components based on a user experience model (performance/power model) for each of the plurality of components. The user experience model (performance/power model) of a component includes a measure of component attribute as a function of component power consumption. The apparatus allocates portions of the total power budget among the user-device components based on priority established by the user experience model. The apparatus may further prioritize the components based on weights assigned to the components.
