PROBLEM TO BE SOLVED: To maintain consistency of memory content shared among a plurality of devices and improve processing speed of the devices at the same time.SOLUTION: In a transfer device, a monitoring unit 15 monitors a request of a processing unit 4 transmitted from an arbitration bus 5 to a memory controller 3. A registration unit 12 checks whether writing processing to an area specified by the monitored request is completed or not and registers the area with an administration table 161 of a storage unit 16 when it is not completed. A reception unit 11 receives a request for data stored in a common memory 2 through an internal bus 6 from a request device 7. An acquisition unit 13 determines whether the request from the request device is for the registered area or not on the basis of the request received by the reception unit 11 and the registered content of the administration table 161, and selects either one of the arbitration bus 5 and the memory controller 3 according to the determination result to acquire the data. A transfer unit 14 transfers the data acquired by the acquisition unit 13 to the request device 7.SELECTED DRAWING: Figure 2 |
