PURPOSE:To arrange and store data in a buffer storage device of the data request source in the order of data request even if data is transferred in the order different from the order of data request, by providing a means for transmission of signals which indicate storage addresses in the data request source. CONSTITUTION:When a request start signal 21 is outputted from an operation controlling circuit 2, a request controlling circuit 3 is started, and contents of a buffer address counter 13 are updated. A data request signal 8 is sent from the request controlling circuit 3 to storage devices 5-7 in the order of RQ1-RQ3, and an address signal is sent from an address register 4 in the order of AD1- AD3 to indicate addresses in storage devices where requested information should be stored. After the storage device 5 finds that the address AD1 for RQ1 is in the storage device 5 itself, the storage device 5 starts the access operation to AD1 and stores contents N of an output signal 22 of the buffer address counter 13 in a data storage address register 51 and transmits contents N when information DT1 is outputted. |
