Next, the operation of this embodiment will be explained. first,
When the business program 2-1 or 2-2 executes a data input/output command (READ/WRITE command), the operating system 3 notifies the input/output processing unit 4 of the input/output request. The input/output processing unit 4 includes peripheral hardware 6
It is determined whether input/output is necessary, and if so, a power-on request is notified to the power control unit 5. In response to this, the power control unit 5 powers on the hardware 6 if it is in the power-off state, waits for the peripheral hardware to start up, and then immediately responds to the power-on request if it is in the power-on state. Upon receiving the response from the power control unit 5, the input/output processing unit 4 performs input/output to the peripheral hardware 6, and notifies the business program 2 of the processing results.

The power control unit 5 performs the following processing depending on the power-on request interval from the input/output processing unit 4, that is, the input/output interval to peripheral hardware. In other words, the number of inputs and outputs per unit time to the peripheral hardware 6 is monitored by using the minimum processing time that is most effective in power saving in the processing from power-on, input/output, and power-off as the minimum non-communication monitoring time for power-off. do. In this case, if the number of inputs/outputs per unit time is less than the value of the previous unit time, the no-communication monitoring time is lengthened, and if it is greater, the no-communication monitoring time is shortened. Further, after a certain input/output, if no further input/output is performed even after the non-communication monitoring time has elapsed, the peripheral hardware 6 is powered off.
