PURPOSE:To improve the efficiency of the operation of a system by simplifying the emergency control processing system, the hard core of a central processor, by linking emergency control processing with interruption control processing at a microprogram level. CONSTITUTION:One central processor 10 and the other central processor 20 are provided with program control parts 11 and 21 and interruption control parts 12 and 22, which are connected to program control parts 11 and 21 via interruption processing request lines 13 and 23. Control line 31 from emergency control circuit 30 is connected to program control parts 11 and 21; when a failure occurs to either unit 10 or 20, circuit 30 is actuated to execute the initial setting of the unit and the constitution control of the building-up system and then program control part 11 o 21 is started. Then, program control part 11 or 21 execute fixed emergency control processing according to the program to set FF for emergency control processing end display and jumps to an interruption control processing program routine, thereby executing the interruption control processing. |
