PROBLEM TO BE SOLVED: To reduce power consumption more effectively in an information processing device with a radio communication function.SOLUTION: In an information processing device 1, a communication module 13 wirelessly communicates with an external apparatus. A first CPU 11 is able to switch between a normal state and a power saving state in which power consumption is lowered than the normal state. A second CPU 12 is able to operate at lower power consumption than the first CPU 11, and accepts an interruption signal output by the communication module 13 when the first CPU 11 is in the power saving state. A switch 14 switches the connection destination of the communication module 13 to the first CPU 11 or second CPU 12 according to a switching signal input from the second CPU 12. On accepting the interruption signal, the second CPU 12 sets the first CPU 11 to the normal state, and switches the switch 14 to the state of connecting the communication module 13 and the first CPU 11.SELECTED DRAWING: Figure 2 |
