PURPOSE:To carry out the transmission of information among plural processors exclusively by a control command, by giving a control command unconditionally to other processors althrough these processors are discontinued by the control command of a processor that has presently a connection. CONSTITUTION:The contents of an auxiliary storage device 4 is transferred to a processor 3 based on a control command of a processor 2. In this case, flip-flop 7 is set and the channel control work group identical with a control command given from the processor 2 is transmitted to a control part 8 via a multiplexer 5. At the part 8, a channel designating field of the channel control word group is inspected. And the flip-flop 7 is reset if the channel designates the processor 3, and the processor 3 is connected to the controller 1. The part 8 reads the contents out of an input/output device 4 based on a reading command if the reading command is set at another field of the channel control word group, and then tansfers the output information to the processor 3 via an output control part 6. |
