Abstract
PURPOSE: To sufficiently perform the function of duplex with a simple constitution, by providing the information processor which is one set with two processors, connecting one input and output to one processor, monitoring the state information of the processor, delivering control information, and selecting the processing under non-operation.
CONSTITUTION: The information processors 1,2 taking one pair with two sets are provided, and the data bus of the processors 1,2 is coupled with the common data bus 7 via the data delivery circuits 3,4, and the information is delivered to the input and output unit 10. Thus, duplex system is constituted. The state information of the transfer circuits 3 and 4 can be monitored with the state monitor circuits 11,13 placed on the data bus selection and control circuits 8,9 corresponded. Further, normally, one processor 1 or 2 is used, delivering information to the input and output unit 10, and if any failure for the processor 1 or 2 used is found out, the selective processing operation is executed by selecting the failed processor to the processor under non-operation with the selection control data delivery 12,14 provided with the control circuits 8 and 9.
