Abstract

PURPOSE: To make it possible to apply a general-purpose microcomputer to duplexed redundancy constitution, by exercising access control between processors via both common buses by coupling common buses of two processing systems by a control circuit.
CONSTITUTION: Common bus 14 to which processor 11, memory 12 and channel system device 19 to be controlled constituting the 1st microcomputer are connected respectively and common bus 24 to which processor 21, memory 22 and channel system device 29 to be controlled are connected respectively are coupled together by bus coupling control circuit 30. Further, processors 11 and 21 are connected directly to bus coupling control circuit 30 via control lines 31 and 32. Only one processor, when in operation, is permitted to occupy both the common buses, and both the processors, when in operation, are so controlled that both the common buses are selected on priority basis of disconnected.
