Abstract
PURPOSE: To increase the reliability of system, by providing the interruption producing circuit outputting an interruption generating signal and supplying the interruption producing signal to other computers, when one set of computer executes write-in or read-out of common memory.
CONSTITUTION: Two sets of computers 1a, 1b are connected to an interface mechanism 4 of a common memory 3 via interface sets 5a, 5b, and this mechanism 4 is connected to the common memory 3. Further, while one set of computer 1a or 1b executes the write-in or read-out of the common memory 3, an interruption generating signal is output from an interruption generating circuit 6 connected to the common memory 3, the interruption generating signal is fed to another computer 1b or 1a via interface mechanisms 7a, 7b, allowing to inform that the common memory 3 is during access.
