Summary:PROBLEM TO BE SOLVED: To improve the convenience to a user by allowing interrupted data processing to be continued in the case that processing of restoring an execution state on the basis of saved data is performed after interruption of data processing and processing of saving the execution state in an information processor. SOLUTION: Stored information in a non-volatile storage means 4 is written back to a volatile storage means 3 in response to power-on or an operation instruction after information related to the execution state including contents of the volatile storage means 3 and an internal state of a CPU 2 is stored in the non-volatile storage means 4, so that information processor is configured so as to restore to the preceding execution state. System internal states other than information related to a real world, such as time information can be completely restored, and data processing (for example, operation of music reproduction) interrupted when saving data in the non-volatile storage means 4 can be transparently restarted from the preceding stop state.
