Abstract—Many portable systems deploy operating systems
(OS) to support versatile functionality and to manage resources,
including power. This paper presents a new approach for using OS
to reduce the power consumption of IO devices in teractive systems.
Low-power OS observes the relationship between hardware
devices and processes. The OS kernel estimates the utilization
of a device from each process. If a device is not used by any
running process, the OS puts it into a low-power state. This paper
also explains how scheduling can facilitate power management.
When processes are properly scheduled, power reduction can
be achieved without degrading performance. We implemented a
prototype on Linux to control two devices experimental results
showed nearly 70 power saving on a network card and a hard
disk drive-Abstract—Many portable systems deploy operating systems
