CONSTITUTION:An interruption-only line 7 which connects the CPUs 1 and 2 to each other is provided and when one CPU 1 tries to synchronize itself with the other CPU 2, the CPU 1 initiates an interruption of NMI level to the other CPU 2 by using the interruption-only line 7 and also causes an interruption of NMI level to itself; and the CPUs 1 and 2 take time data of a work station 4 out of a common memory 3 at the same time and set the data.</p> |
