Abstract
PURPOSE: To enable to separate the failed part only from other parts onfialure without attecting on others, by constituting one processor so that it only is connectable to the terminal unit, when simultaneous delivery request is taken place from two sets of processors.
CONSTITUTION: In the system using two sets of processors 1, 2 which use one terminal unit 5 with he selection circuits 3 and 4 in time sharing manner, when the transfer request signal 11 or 21 from the units 1, 2 is inputted, bistable circuit consisting of OR gates 32, 42 and NAND gates 33, 43 connected to the pulse generating circuits 31 and 41 generating the output to connect the corresponding units 1, 2 to the terminal unit 5 is provided. Further, in separating the corresponded part of one bistable circuit, the switches 34, 44 operated with the output of the bistble circuit and connecting other units 1, 2 to the terminal unit 5 are respectively provided.
