摘要： 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.

摘要： 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.

摘要： The various aspects provide for an IC design and methods for utilizing the IC design to emulate corner case ICs during power/thermal testing of a test system by installing a specially chosen IC on the test system. The chosen IC may be a fully functioning IC that also includes a leakage-add controller and a current leak circuit. The current leak circuit may simulate additional current leakage on the IC and may be driven by the leakage-add controller. The chosen IC may also include a programmable voltage table for adjusting the chosen IC's operational voltage. The chosen IC may emulate the thermal characteristics of various corner-case ICs while performing normal IC activities on the test system during power/thermal testing, thereby eliminating current limitations in thermal/power testing of test systems due to the difficulty of providing corner-case ICs and testing those corner-case ICs on various test systems.

摘要： 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.

摘要： The various aspects provide for a device and methods for intelligent multicore control of a plurality of processor cores of a multicore integrated circuit. The aspects may identify and activate an optimal set of processor cores to achieve the lowest level power consumption for a given workload or the highest performance for a given power budget. The optimal set of processor cores may be the number of active processor cores or a designation of specific active processor cores. When a temperature reading of the processor cores is below a threshold, a set of processor cores may be selected to provide the lowest power consumption for the given workload. When the temperature reading of the processor cores is above the threshold, a set processor cores may be selected to provide the best performance for a given power budget.

摘要： Various embodiments of methods and systems for mode-based reallocation of workloads in a portable computing device (“PCD”) 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 performance capabilities or strengths, and because more than one of the processing components may be capable of processing a given block of code, mode-based reallocation systems and methodologies can be leveraged to optimize quality of service (“QoS”) by allocating workloads in real time, or near real time, to the processing components most capable of processing the block of code in a manner that meets the performance goals of an operational mode. Operational modes may be determined by the recognition of one or more mode-decision conditions in the PCD.

摘要： 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.
