Abstract
Official abstract text for this publication.
A system and method for power management by providing advance notice of events. The method includes snooping a register of an operating system timer to determine a timer period associated with a scheduled event. A unit of a computer system is identified that is in a low power state. A wake up latency of the unit is determined that is based on the low power state. An advance period is determined based on the wake up latency. An advance notice of the operating system timer is triggered based on the timer period and the advance period to wake up the unit.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for power management, comprising: snooping a register of an operating system timer to determine a timer period associated with a scheduled event; identifying a first unit of a computer system that is in a first low power state; determining a first wake up latency of said first unit based on said first low power state; determining a second unit of said processor system that is in a second low power state; determining a second wake up la…
