Abstract
The present invention is employed in the environment in which a plurality of OSs exist on a single processor having a power-saving function, and includes a primary OS for receiving a timer interrupt from a hardware timer after a predetermined time lapse and a secondary OS treated as a task to be executed by the primary OS, wherein upon receiving the timer interrupt, the primary OS determines whether there exists any task to be executed, and interrupts the secondary OS if there is any task to be executed on the secondary OS.
