PURPOSE:To eliminate special hardware and reduce the scale of a device, and improve the reliability by composing one arithmetic control unit of two function- decentralized processors, and combining plural units into an (n)-tuple system. CONSTITUTION:Arithmetic control units 1a-1c each consist of two function- decentralized processors, i.e. a control processor and a diagnostic processor. When a start command is supplied to an optical arithmetic control unit, the arithmetic control unis 1a-1c informs a rise command by software through transmission lines 3 and 4 and also collate and synchronize data. A majority decision logical circuit 2 receives the input signals from the arithmetic control units 1a-1c to generate an output based upon majority decision logic, which is supplied to an external equipment through a control output line 7 and also fed back to the arithmetic control units 1a-1c through a control output monitor line 8. |
