The Power Management Unit (PMU) is a microcontroller that governs power functions of digital platforms. This microchip has many similar components to the average computer, including firmware and software, memory, a CPU, input/output functions, timers to measure intervals of time, and analog to digital converters to measure the voltages of the main battery or power source of the computer. The PMU is one of the few items to remain active even when the computer is completely shut down, powered by the backup battery.

Motion sensor data processing using various power management modes
Systems and methods for processing motion sensor data using various power management modes of an electronic device are provided. Power may be provided to a motion sensor during a first power mode of the device. In response to the motion sensor detecting a motion event with a magnitude exceeding a threshold, the sensor may transmit a wake up signal to a power management unit of the device. In response to receiving the wake up signal, the power management unit may switch the device to a second power mode. The device may provide power to a processor and load the processor with a motion sensing application when switching to the second power mode. During the second power mode, motion sensor data may be processed to determine that the motion event is not associated with an intentional user input and the device may return to the first power mode.

Headsets and Headset Power Management
ActiveUS20070076897A1Limited functionReduce power consumptionSignal processingHeadphones for stereophonic communicationPower Management UnitEngineering
The invention relates to an energy saving headset that comprises a power management unit operable to reduce the power consumption of the headset when a user is not present. The power management unit uses capacitive sensing to detect the presence of the user. Capacitive sensing is advantageous since it provides a flexible and reliable sensor that can accurately detect the presence or absence of a user either by detecting user proximity or user contact. Moreover, in various embodiments, the sensitivity of a capacitive sensor may be adjusted to account for user movement or changes in environmental conditions, such as, for example, the presence of water, or sweat, on the headset to further improve sensing reliability. The invention further relates to headsets using user presence signals based on capacitive sensing to control other functions of the headset or to control external devices to which the headset is connected, either wirelessly or by wires.

An integrated circuit includes a CPU, a power management unit and plural functional units each dedicated to executing different functions. The power management unit controls the threshold voltage of the different functional units to optimize power / performance operation of the circuit and intelligent power management control responds to the instruction stream and decodes each instruction in turn. This information identifies which of the functional units are required for the particular instruction and by comparing that information to power status, the intelligent power control determines whether the functional units required to execute the command are at the optimum power level. If they are, the command is allowed to proceed, otherwise the intelligent power control either stalls the instruction sequence or modifies process speed.

Mechanisms to avoid inefficient core hopping and provide hardware assisted low-power state selection
InactiveUS20110161627A1Energy efficient ICTConditional code generationPower Management UnitComputer science
An apparatus and method is described herein for avoiding inefficient core hopping and providing hardware assisted power state selection. Future idle-activity of cores is predicted. If the residency of activity patterns for efficient core hop scenarios is predicted to be large enough, a core is determined to be efficient and allowed. However, if efficient activity patterns are not predicted to be resident for long enough—inefficient patterns are instead predicted to be resident for longer—then a core hop request is denied. As a result, designers may implement a policy for avoiding core hops that weighs the potential gain of the core hop, such as alleviation of a core hop condition, against a penalty for performing the core hop, such as a temporal penalty for the core hop. Separately, idle durations associated with hardware power states for cores may be predicted in hardware. Furthermore, accuracy of the idle duration prediction is determined. Upon receipt of a request for a core to enter a power state, a power management unit may select either the hardware predicted power state, if the accuracy is high enough, or utilize the requested power state, if the accuracy of the hardware prediction is not high enough.
