    • An information processing device (1) includes a main CPU (2) and a sub CPU (3). The main CPU (2) 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 (2) as the idle processing when the task processing is not executed. The sub CPU (3) 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 (2). The main CPU (2) 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.
    • 信息处理装置(1)包括主CPU(2)和副CPU(3)。 主CPU(2)具有管理任务处理和空闲处理的时间表的功能,并且执行睡眠控制,当不执行任务处理时,执行休眠控制,这降低了作为空闲处理的主CPU(2)的功耗。 子CPU(3)测量执行睡眠控制的经过时间,检测在睡眠控制期间发生的中断事件,并通知直到中断事件发生到主CPU(2)的经过时间。 主CPU(2)根据经过时间的通知终止睡眠控制,并反映出时间表中的经过时间。 结果,可以解决由睡眠控制引起的定时器的不一致性,并且提供即使执行了睡眠控制也能够正确使用调度器的信息处理设备。

    • The invention maintains optimum sound quality even when a listener changes his/her angle formed between a sound wave emitting axis of an ultrasonic transducer and a front direction axis of the listener with respect to the sound wave emitting axis. An ultrasonic speaker system of the invention includes an angle measuring unit that measures a listener angle as an angle formed between a sound wave emitting axis of the ultrasonic transducer and an axis indicating a listener's front direction; a control information transmitting unit that transmits control information including listener angle information obtained by the angle measuring unit; a control information receiving unit that receives the control information; and a control unit that controls the signal processing performed by a signal processing unit based on the listener angle information included in the control information.
