<P>PROBLEM TO BE SOLVED: To improve an operation rate of a control object of a bus synchronized duplex computer system. <P>SOLUTION: In a computer system for controlling an operation of a control object from a result of collating, in a collation part 4, respective pieces of data of two arithmetic parts 2A and 2B which synchronously perform the same arithmetic processing to the same information, the bus synchronized duplex computer system includes a standby arithmetic part 3 aside from the two arithmetic parts 2A and 2B, and switches an abnormal side arithmetic part to the standby arithmetic part 3 when the standby arithmetic part 3 is normal and one of the two arithmetic parts 2A and 2B is abnormal from the result of mutually collating, in a different collation part 5, the respective pieces of data of the two arithmetic parts 2A and 2B and the standby arithmetic part 3 before the collation in the collation part 4. <P>COPYRIGHT: (C)2013,JPO&INPIT |
