<P>PROBLEM TO BE SOLVED: To provide a module for changing the operating frequency of each processor while holding a synchronized state in which a plurality of processors simultaneously perform the same processing in a synchronized manner. <P>SOLUTION: The module includes a plurality of modules having the same configurations which have processors for executing the same processing in a synchronized manner, interruption which is notified to the processors of the plurality of modules is included in the plurality of modules of a fault tolerant computer in which the processors of the plurality of modules are simultaneously notified of the interruption, the module which being characterized by including: instruction input means for inputting a frequency change instruction; processor control means for, when inputting the frequency change instruction, notifying the processor of interruption; and the processor for, when receiving the interruption, interrupting the same processing, and for changing the frequency of the processor, and for, after the lapse of a predetermined time which is equal to or more than a time when the frequencies of the processors of all the modules are switched from the time of the change of the frequency, resuming the interrupted same processing. <P>COPYRIGHT: (C)2013,JPO&INPIT |
