Abstract: Various embodiments of methods and systems for dynamically adjusting operating frequency settings of one or more processing components in a portable computing device (“PCD”) are disclosed. One such method involves receiving a request to adjust an operating frequency setting of a processing component to a required frequency (“F_req”) to process a workload. Factor readings associated with the operating capacity of the processing component may be taken. Based on the readings, performance curves associated with the processing component may be queried. The performance curves are used to determine the optimal operating frequency (“F_opt”) for the processing component. The F_opt is compared to the F_req and, if the F_req is less than F_opt, the operating frequency setting of the processing component is set to F_opt. Advantageously, as compared to F_req, at F_opt workload processing may be more efficient and a low power mode may be entered sooner.

Abstract: Various embodiments of methods and systems for dynamically adjusting a peak dynamic power threshold are disclosed. Advantageously, embodiments of the solution for peak dynamic power management optimize a peak dynamic power threshold based on estimations of real-time leakage current levels and/or actual power supply levels to a power domain of a system on a chip (“SoC”). In this way, embodiments of the solution ensure that a maximum amount of available power supply is allocated to dynamic power consumption for processing workloads at an optimum performance or quality of service (“QoS”) level without risking that the total power consumption (leakage power consumption+dynamic power consumption) for the power domain exceeds the power supply capacity.

Abstract: Methods and devices for managing data flows for concurrent multimedia applications executing on a device including a SoC, in response to determining that a temperature or power consumption exceeds a threshold are disclosed. A lowest priority data flow may be identified. A data flow path associated with the identified lowest priority data flow may be traced. A multimedia parameter of any hardware module along the data flow path may be reduced. When the temperature or power consumption no longer exceeds the threshold, a highest priority data flow among the multimedia applications that has had the multimedia parameter reduced may be identified. A data flow path for a data flow associated with the identified highest priority data flow may be traced. The multimedia parameter may be restored to an original value along the traced data flow path for the data flow associated with the identified highest priority data flow.

Abstract: Various embodiments of methods and systems for intelligent multimedia-based thermal power management implemented in a portable computing device (“PCD”) are disclosed. To reduce or increase power consumption in the PCD, embodiments adjust one or more visual multimedia parameters, the settings of which contribute to power consumption associated with an overall multimedia workload. The selection of visual multimedia parameters for setting adjustment is a function of the change in user experience versus the change in power consumption that will likely result from the setting adjustment. Exemplary visual multimedia parameters for which settings may be adjusted by certain embodiments include, but are not limited to, color depth, display brightness, GPU processing resolution, image dynamics algorithm selection, resolution scaling ratios and frames per second processing rates.
