<P>PROBLEM TO BE SOLVED: To provide an information processing device capable of recovering from a power-saving mode at high speed without increasing a cost. <P>SOLUTION: In transiting to a power-saving mode, a volatile memory 33 is controlled so as to continuously hold a program loaded to the volatile memory 33 during a power-saving mode, and a logical value indicating that an information processing device is in the power-saving mode is set to an input-output port of a sub-microcomputer 21. In activating the device, a processor 32 determines whether or not the logical value indicating the device is in the power-saving mode is set to the input-output port. In the case where the logical value is set, the processor recognizes it as recovery from the power-saving mode, and executes the program held by volatile memory 33. On the other hand, in the case where the logical value is not set, the processor 32 recognizes it as regular activation, and loads a program held in a non-volatile memory 34 to the volatile memory 33 to execute the loaded program. <P>COPYRIGHT: (C)2013,JPO&INPIT |
