Abstract
An information processing device () includes a main CPU () and a sub CPU (). The main CPU () is provided with a function of managing schedules of task processing and idle processing and executes sleep control which reduces power consumption of the main CPU () as the idle processing when the task processing is not executed. The sub CPU () measures elapsed time during which the sleep control is executed, detects an interrupt event occurring during the sleep control, and notifies the elapsed time until the interrupt event occurs to the main CPU (). The main CPU () terminates the sleep control in accordance with the notification of the elapsed time and reflects the elapsed time in the schedule. As a result, inconsistency of a timer caused by the sleep control can be solved, and the information processing device which can use a scheduler correctly even if the sleep control is executed is provided.
