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

Techniques are provided for operating a computing system in a peak power mode while avoiding increased degradation of a battery. The peak power mode include cycles with peak and off-peak currents. The amplitude and duration of the peak and off-peak currents are governed by a thermal/heat budget of the battery. A processor can read the battery information during usage and calculate one or more parameters which are derived from heat. If a parameter is smaller than a reference value, the processor can update the peak power parameters to provide an increase in peak current/power and/or duration. If a parameter is larger than the reference value, no heat budget is available to provide an increase in peak current/power and/or duration. The thermal/heat budget can be enforced over each cycle of the peak power mode or in a summation over multiple cycles.

Battery heat balancing apparatus and method during peak mode

Methods, apparatus, and systems to dynamically schedule a workload to among compute blocks based on temperature are disclosed. An apparatus to schedule a workload to at least one of a plurality of compute blocks based on temperature includes a prediction engine to determine (i) a first predicted temperature of a first compute block of the plurality of compute blocks and (ii) a second predicted temperature of a second compute block of the plurality of compute blocks. The apparatus also includes a selector to select between the first compute block and the second compute block for assignment of the workload. The selection is based on which of the first and second predicted temperatures is lower. The apparatus further includes a workload scheduler to assign the workload to the selected one of the first or second compute blocks.

Methods, apparatus, and systems to dynamically schedule workloads among compute resources based on temperature

Three components are used to adjust the CPU peak power based on the USB TYPE-C device states. These components include operating system (OS) Peak Power Manager, USB TYPE-C Connector Manager, and USB TYPE-C Protocol Device Driver. The USB TYPE-C Connector Manager sends a synchronous request to the OS Peak Power Manager when a USB TYPE-C power sink device is attached or detached, and the USB TYPE-C Protocol Device Driver sends a synchronous request to the Peak Power Manager when the power sink transitions device state. The Peak Power Manager takes power budget from the CPU when the USB TYPE-C connector is attached to a power sink and is active (e.g., high power device state), and gives back the power budget to the CPU for performance when the USB TYPE-C connector is either detached or the attached and power sink device is idle (lowest device state).

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.
