PURPOSE:To use freely a system bus and to execute the assigned processing beforehand by providing a system bus linking device to control an information channel between unit systems and selecting the channel in accordance with the address of the transmitting information. CONSTITUTION:At a system bus linking part of multi-processors MP1-MP4 as a unit system, system bus linking devices BC1-BC3 are provided, and a system bus BUS between unit systems is linked. The multi-processor connected with the system bus linking devices BC1-BC3 as starting point respectively is set beforehand, collated with address information and the channel of transmission information is controlled. When transmission is executed from a processor P2 of the multiprocessor MP4 to a processor P2 of the multiprocessor MP2, the system bus BUS can be freely used at the multiprocessor MP1 without the channel leading to the address. |
