<P>PROBLEM TO BE SOLVED: To smoothly perform alternative processing when a defect has occurred at one of multiple processor cores while achieving memory protection. <P>SOLUTION: An information processing device comprises: multiple processing means; a shared memory which is accessed by the multiple processing means and assigned to each processing means as an available dedicated area; a control means controlling an operational state of the multiple processing means; and a hardware means keeping identification information of the multiple processing means. The control means gives other processing means instruction to perform alternative processing when one of processing means of the multiple processing means is in an abnormal state and makes the dedicated area assigned to the processing means in the abnormal state available for the processing means which performs the alternative processing using the identification information of the processing means in the abnormal state kept by the hardware means. <P>COPYRIGHT: (C)2012,JPO&INPIT |
