PURPOSE:To improve throughput by simultaneously receiving a data transfer request between a main storage device and an extended storage device outputted from a processor and a data transfer request between the 2nd main storage device and the extended storage device outputted from a rapid operation processor. CONSTITUTION:In the case of transferring data between a magnetic disk device 12 and the extended storage device 7 e.g., data transfer from the device 12 to a controlling main storage device 5 is executed by means of an I/O control device 2. On the other hand, an extended storage data transfer control device 9 is started so as to transfer data from the device 5 to the device 7 under the control of a central processor 3 or the device 2. The device 9 controls data transfer between the device 7 and the device 5, and at the time of completing the transfer, the completion is reported to the device 3 or the device 2. Thereby, data transfer between the device 12 and the device 7 can be attained without passing the device 4. Thus, the rapid processing of a vector instruction or a scalar instruction to a user program being executed by the device 4 can be executed without being interrupted.
