PURPOSE:To attain the reduction of total cost and to minimize the increase in signal lines, by providing the same input and output interface to a master unit, in a system in which memories and processors are connected on a common bus. CONSTITUTION:In a system in which a main storage device 1 and plural processor units 3-5 are connected on a common bus 2, the processor unit for controlling an IO is defined as the master unit 3, and the same interface 7 as input and output interfaces 8, 9 is provided between the master unit 3 and the other slave units 4, 5, and a channel for the communication between processors is formed via the interface 7, then the communication between the processors does not give hindrance for the data transfer on the common bus. |
