    Abstract: A method and apparatus for providing telemetry for use in power control functions is disclosed. A system includes an integrated circuit (IC) having a first power management circuit. The IC also includes a number of functional circuit blocks within a number of different power domains. A second power management circuit is implemented external to the IC and includes a number of voltage regulators. Each of the power domains is coupled to receive power from one voltage regulators. During operation, the first power management circuit may send commands requesting the change of one or more voltages provided to the IC. The second power management circuit may respond by performing the requested voltage change(s), and may also provide telemetry data to the first power management circuit. The second power management circuit may also provide telemetry data responsive to receiving a no operation command from the first power management circuit.

    Abstract: The subject matter of the disclosure relates to low temperature power throttling at a mobile device to reduce the likelihood of an unexpected power down event in cold weather environments. A mobile device employing a power management solution may be configured to determine that a monitored temperature at the mobile device (at the battery of the mobile device) is below a first threshold level, and whether a hardware component (such as a camera) is active or inactive. Then, based on these determinations, the mobile device can select a throttle setting from a first set of throttle settings when the hardware component is active, and a second set of throttle settings when the hardware component is inactive. Subsequently the mobile device can throttle power consumption for one or more components of the mobile device according to the selected throttle setting.

    Abstract: In an embodiment, a system includes multiple power management mechanism operating in different time domains (e.g., with different bandwidths) and control circuitry that is configured to coordinate operation of the mechanisms. If one mechanism is adding energy to the system, for example, the control circuitry may inform another mechanism that the energy is coming so that the other mechanism may not take as drastic an action as it would if no energy were coming. If a light workload is detected by circuitry near the load, and there is plenty of energy in the system, the control circuitry may cause the power management unit (PMU) to generate less energy or even temporarily turn off. A variety of mechanisms for the coordinated, coherent use of power are described.

    Abstract: A device implementing adaptive memory performance control by thread group may include a memory and at least one processor. The at least one processor may be configured to execute a group of threads on one or more cores. The at least one processor may be configured to monitor a plurality of metrics corresponding to the group of threads executing on one or more cores. The metrics may include, for example, a core stall ratio and/or a power metric. The at least one processor may be configured to determine, based at least in part on the plurality of metrics, a memory bandwidth constraint with respect to the group of threads executing on the one or more cores. The at least one processor may be configured to, in response to determining the memory bandwidth constraint, increase a memory performance corresponding to the group of threads executing on the one or more cores.

    Abstract: The invention provides a technique for targeted scaling of the voltage and/or frequency of a processor included in a computing device. One embodiment involves scaling the voltage/frequency of the processor based on the number of frames per second being input to a frame buffer in order to reduce or eliminate choppiness in animations shown on a display of the computing device. Another embodiment of the invention involves scaling the voltage/frequency of the processor based on a utilization rate of the GPU in order to reduce or eliminate any bottleneck caused by slow issuance of instructions from the CPU to the GPU. Yet another embodiment of the invention involves scaling the voltage/frequency of the CPU based on specific types of instructions being executed by the CPU. Further embodiments include scaling the voltage and/or frequency of a CPU when the CPU executes workloads that have characteristics of traditional desktop/laptop computer applications.

    Abstract: An electronic device may have electrical components that produce heat during operation. An electronic device may also be heated by sunlight incident on the device. A thermal management model may take into account device structures such as housing materials in modeling the thermal behavior of the device. Temperature sensors in the device may be used to measure internal temperatures. The model may use temperature measurements and other data such as environmental data measured with sensors in predicting temperatures for one or more regions in a device. In response to prediction of a temperature greater than a predetermined threshold, the device may take remedial action to avoid overheating. Remedial action may include adjusting electrical components so that they produce less heat, activating a heat blocking component such as an electronic shutter, and reducing communications activity levels and other software activity levels.
