摘要： Various embodiments of methods and systems for determining the thermal status of processing components within a portable computing device (“PCD”) by measuring leakage current on power rails associated with the components are disclosed. One such method involves measuring current on a power rail after a processing component has entered a “wait for interrupt” mode. Advantageously, because a processing component may “power down” in such a mode, any current remaining on the power rail associated with the processing component may be attributable to leakage current. Based on the measured leakage current, a thermal status of the processing component may be determined and thermal management policies consistent with the thermal status of the processing component implemented. Notably, it is an advantage of embodiments that the thermal status of a processing component within a PCD may be established without the need to leverage temperature sensors.

摘要： Methods and systems for managing thermal load distribution on a portable computing device (“PCD”) include storing on a PCD a plurality of thermal load steering scenarios which identify simulated thermal load conditions for the PCD, corresponding simulated workloads that produced the simulated thermal load conditions, and thermal load steering parameters for steering the simulated thermal load to a predetermined spatial location on the PCD. A scheduled workload for the PCD is monitored to identify a match with one of the thermal load steering scenarios so that the workload may be scheduled according to a thermal load steering parameter. Another method includes initiating a thermal mitigation technique on a PCD and determining a current graphical load being processed by the PCD. A graphics feature associated with the current graphical load is identified. The graphics feature is then disabled while maintaining a frame rate to reduce temperature of the PCD.

摘要： The aspects enable a computing device or microprocessor to scale the frequency and/or voltage of a processor to an optimal value balancing performance and power savings in view of a current processor workload. Busy and/or idle duration statistics are calculated from the processor during execution. The statistics may include a running average busy and/or idle duration or idle/busy ratio, a variance of the running average and a trend of the running average. Current busy or idle durations or an idle-to-busy ratio may be computed based on collected statistics. The current idle-to-busy ratio may be compared to a target idle-to-busy ratio and the frequency/voltage of the processor may be adjusted based on the results of the comparison to drive the current running average toward the target value. The target value of idle-to-busy ratio may be adjusted based on the calculated variance and/or trend values.

摘要： Methods and systems for leveraging temperature sensors in a portable computing device (“PCD”) are disclosed. The sensors may be placed within the PCD near known thermal energy producing components such as a central processing unit (“CPU”) core, graphical processing unit (“GPU”) core, power management integrated circuit (“PMIC”), power amplifier, etc. The signals generated by the sensors may be monitored and used to trigger drivers running on the processing units. The drivers are operable to cause the reallocation of processing loads associated with a given component's generation of thermal energy, as measured by the sensors. In some embodiments, the processing load reallocation is mapped according to parameters associated with pre-identified thermal load scenarios. In other embodiments, the reallocation occurs in real time, or near real time, according to thermal management solutions generated by a thermal management algorithm that may consider CPU and/or GPU performance specifications along with monitored sensor data.

摘要： The aspects enable a computing device or microprocessor to adjust the operations of a processor in view of a current processor workload based on a histogram-like data structure. A histogram-like data structure characterizing one of processor busy and/or idle durations or busy/idle ratios is generated at runtime and used to model the processor workload. The processor workload is used to predict future processing requirements and to adjust the processor's operations such that they are commensurate with the processing and workload requirements. The histogram-like data structure may alternatively be used to estimate a current quality of service (QoS) of a communication link so that link management actions may be taken.
