PURPOSE:To provide a very high data transfer throughput by physically dividing so as to shorten data transfer cycles limited due to transfer distance of signals through physical division. CONSTITUTION:Units 1 and 2 constituting a system are connected by way of an occupation line 3 indicating bus occupational states of physically divided partial buses, a data line 4 and a state line 5 indicating data transfer results. The occupation information on the occupation line 3, the data on the dataline 4 and the data transfer results an the state line 5 are made to be transferred in the single direction. A scheduler 9 which mediates bus use requests front the units which are going to transfer data supplies with identifiers for the units that use partial bus as occupation information. Each unit 1 and 2 independently outputs and receives data based upon the occupation information specification given by the scheduler 9, permitting plural independent data transferred on the bus. |
