INFORMATION PROCESSING DEVICE, PROGRAM UPDATE METHOD, AND INFORMATION PROCESSING SYSTEM

摘要

Provided is an information processing device which records in a nonvolatile storage device (13), a management flag (32) for managing the states of N pieces of division data 0 to N-1 constituting a program (31) to be updated, references the management flag (32) when specifying the division data to be updated, and uses update data (35) to update the division data to be updated. If the update of the program (31) to be updated is interrupted, the management flag (32) is referenced when resuming the update, so as to identify the division data which has not been updated upon the update interruption and specify the identified division data to be the division data to be updated.
