A first circuit to receive from a sensor a thermal condition of a voltage regulator while circuitry comprising the voltage regulator is to regulate delivery of power to a power domain having first and second components. The circuitry is to control a first power consumption rate of the first component based on a first parameter and control a second power consumption rate of the second component based on a second parameter. The first circuit monitors the thermal condition and generates an evaluation result based on a test criterion. A second circuit receives from the first circuit a signal based on the evaluation result. Based on the signal, the second circuit is to signal the circuitry to change the first parameter. An amount of any change to the second parameter based on the evaluation result is different than an amount of change to the first parameter based on the evaluation result.

Thermally optimized power delivery

A hardware and/or software (e.g., a controller and/or firmware or software) that monitors a remaining capacity of a battery and adjusts a continuum of system performance settings ranging from best performance to best energy efficiency. The controller starts with best performance setting (at the expense of energy efficiency), and then the controller gradually shifts toward energy efficiency setting (at the expense of performance) when a battery usage exceeds a pre-defined drain rate (e.g., there is a deficit in the battery remaining capacity until the next charge). The controller reverts from energy efficiency setting towards high performance setting when the battery drain rate or discharge rate slows down (e.g., there is a surplus in the battery remaining capacity until the next charge).

Predictable battery power management apparatus and method

Software and/or hardware to monitor system usage including how long system ran on a battery or with AC adapter power. The software and/or hardware judges whether fast charging is needed and/or how much charge is needed, and optimizes battery charging settings.

Context-based battery charging apparatus and method

A driver (e.g., a firmware or software) that improves the performance of the system-on-chip (SoC) in battery mode. The driver is a Peak Power Manager (PPM) which allows drastically higher SoC peak power limit levels (and thus higher Turbo performance) in battery mode. The PPM sets the Vth threshold voltage (the voltage level at which the platform will throttle the SoC) in such a way as to prevent the system from unexpected shutdown (or black screening). The PPM calculates the Psoc,pk SoC Peak Power Limit (e.g., PL4), according to the threshold voltage (Vth). These are two dependent parameters, if one is set, the other can be calculated. The scheme by the PPM is used to optimally set one parameter (Vth) based on the system parameters, and the history of the operation.

Processor peak current control apparatus and method

In one embodiment, a processor includes: at least one core; and a power controller coupled to the at least one core. The power controller may include: a workload monitor circuit to calculate a background task ratio based on a first amount of time that the at least one core executed background tasks during an active duration; and a control circuit to dynamically apply a power management policy for a background mode when the background task ratio exceeds a background mode threshold, the power management policy for the background mode to reduce power consumption of the processor. Other embodiments are described and claimed.

System, apparatus and method for dynamically adjusting platform power and performance based on task characteristics

Methods, apparatus, systems, and articles of manufacture are disclosed. In one example, a compute device to manage energy usage and compute performance includes at least one memory, instructions, and processor circuitry. The processor circuitry executes the instructions to determine a system power mode based on first telemetry data associated with the compute device. The processor circuitry executes the instructions to provide user activity data and second telemetry data associated with the compute device to a classification system. The processor circuitry executes the instructions to configure a plurality of parameters to manage power consumption and performance of the compute device based on a classification by the classification system.

Methods and apparatus to manage energy usage and compute performance

Methods, apparatus, systems and articles of manufacture are disclosed to monitor and manage usage of resources on a computing platform. An example apparatus includes a processor and a subsystem. The example processor includes a modified operating system, the operating system modified to monitor application execution via the processor to determine a usage scenario for the apparatus. The example processor includes an index generator to generate a system usage scenario index quantifying a snapshot of the usage scenario for the processor and the subsystem of the apparatus. The example processor includes a rebalancer to reallocate resources of at least one of the processor or the subsystem based on the system usage scenario index.

Usage scenario based monitoring and adjustment

Methods, apparatus, systems, and articles of manufacture are disclosed to improve computing device power management. An example apparatus includes a usage classifier to classify usage of a computing system, a low battery probability determiner to determine a probability of the computing system operating with a low battery capacity based on the classification, a policy reward determiner to determine an adjustment of a policy based on at least one of the classification or the probability, and determine a battery capacity of the computing system in response to the adjustment, and a policy adjustor to adjust the policy in response to the battery capacity satisfying a threshold.

Methods and apparatus to improve computing device power management

Described are mechanisms and methods for implementing highly configurable power delivery management policies. An apparatus may comprise a first circuitry, a second circuitry, a third circuitry, and a fourth circuitry. The first circuitry may include a memory to store a first table having one or more first entries and to store a second table having one or more respectively corresponding second entries. The second circuitry may, upon the occurrence of an event, test a condition specified by an entry in the first table. The third circuitry may, upon the test of the condition having a positive result, evaluate a set of one or more parameters as specified by an entry in a second table corresponding with the entry in the first table. The fourth circuitry may initiate a power-management action based upon the evaluation of the set of one or more parameters.

Highly configurable power-delivery management policy

A wireless communication device for communicating across a wireless communication channel includes one or more processors configured to determine whether a further device is generating a radio frequency interference at an operating frequency; transmit a request message to the further device requesting the further device vacate the operating frequency based on the determination that the further device is generating radio frequency interference; receive a response message from the further device; and generate an instruction based on the response message.

Methods and devices for dynamically avoiding radio frequency interference

Peak power setting circuitry is provided to set a peak power value for an integrated circuit device. A power supply interface is to receive a value to estimate a peak power capacity of a power supply serving the integrated circuit device and processing circuitry is provided to calculate an approximate peak power for the integrated circuit device. A peak power for the integrated circuit device is determined by increasing the approximate peak power depending on an amount by which the integrated circuit device power is reduced in response to assertion of a throttling signal.

Peak power determination for an integrated circuit device

When power is provided through a USB-C cable from a source device to a sink device, a sudden connection or disconnection of the cable between the two devices may cause a sudden power surge or power drop in at least one of those devices, leading to other problems. To avoid this sudden event from causing potential damage or disruption to one of the devices, in some embodiments a CC pin in the cable is used to announce the impending connection/disconnection, and the device may throttle back its power consumption before power is actually applied to or removed from the power pins.
