DYNAMIC POWER-DOWN MANAGEMENT IN A COMPUTING DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17737997 titled 'DYNAMIC POWER-DOWN MANAGEMENT IN A COMPUTING DEVICE
Simplified Explanation
The abstract describes a method for determining whether to power down a subsystem in a computing device based on its idle time and various measurements.
- The decision to power down is based on the subsystem's current consumption, bandwidth usage, and efficiency.
- A count value is calculated using predetermined relations between the measurements.
- The subsystem is powered down if it has been idle for a duration equal to or longer than the calculated count value.
Original Abstract Submitted
In a computing device it may be determined whether to power down a subsystem based on how long the subsystem has been idle and based on one or more measurements of subsystem current consumption, subsystem bandwidth usage, and subsystem efficiency. An idle power-down count value may be determined based on the measurements, using predetermined relations among subsystem current consumption, subsystem bandwidth usage, and subsystem efficiency. The subsystem may be powered down based on a determination of whether the subsystem has been idle for an interval not less than the idle power-down count value.
