Abstract

PURPOSE:To obtain an input and output bus device of hierarchy type bus-loop constitution which has a function of controlling triangular transfer, by controlling a transfer path with a signal stored at an interbus coupling part. CONSTITUTION:For triangular transfer by an input-output bus device having processors 51-53 looped, for example, as shown in the figure, when the 1st processor starts data transfer from one input-output equipment to the 2nd processor, a signal showing that the 2nd processor is to receive data from the said input-output equipment is stored at interbus coupling parts 59-61 which connects a bus loop, where the 2nd processor belongs, to another bus loop. With this signal, the route from the actuated input-output equipment to the 2nd processor is controlled.
