<p><P>PROBLEM TO BE SOLVED: To diagnose an interface of a preliminary system while reducing an influence of operation of the interface of the preliminary system. <P>SOLUTION: This information processor is equipped with: an interface part of an operation system; an interface part of a standby system; a first changeover part for connecting an external device to either of the interface parts; a second changeover part for connecting an internal processing part to either of the interface parts; and a control part. When an information processing condition in the interface part of the operation system satisfies a predetermined condition, the control part makes the first changeover part output information inputted from the external device to the interface part of the operation system and the interface part of the standby system, and store the information as comparison object information, makes the second changeover part input by return information processed by the interface part of the standby system and thereafter outputted, to the interface part of the standby system, and makes the first changeover part execute diagnosis by comparing information outputted by the interface part of the standby system, with the comparison object information. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
