摘要： 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.

摘要： An information processing system in which a sub-CPU is provided besides a main CPU to carry out those kinds of processing and power supply control that may be executed at time intervals of a short period, so that the power consumption of the information processing system can be reduced without lowering the processing speed of the information processing system. The sub-CPU of a type operating at a low speed, driven by a low voltage and consuming a small amount of power carries out those kinds of processing including monitoring an input from a keyboard, counting the output of a timer and monitoring and controlling a power supply control circuit, and, during waiting arrival of a key input, the main CPU is placed in its halt mode consuming a very small amount of power. The sub-CPU instructs to selectively turn off the power supply for an input/output unit not in use among a display unit, a modem, an FDD, an extension slot, etc., whereby the power consumption of the information processing system can be reduced without lowering the processing speed of the information processing system.
摘要翻译：一种信息处理系统，其中除了主CPU之外还提供了副CPU，以执行可以在短周期的时间间隔执行的那些处理和电源控制，使得信息处理系统的功耗可以减少信息处理系统的处理速度。由低电压驱动并消耗少量电力的低速操作的副CPU执行这些处理，包括监视来自键盘的输入，对定时器的输出进行计数和监视和控制电源控制电路，并且在等待到达键输入期间，主CPU处于停止模式，消耗非常少量的电力。子CPU指示选择性地关闭在显示单元，调制解调器，FDD，扩展槽等之间未使用的输入/输出单元的电源，由此信息处理系统的功耗可以是降低了信息处理系统的处理速度。
