ABSTRACT:
A system information storage section stores access information showing attributes for accessing a storage peculiar to a processor and storages peculiar to other processors by relating the access information to data. The system information storage section stores space identifying information for identifying each of plural kinds of virtual spaces allocated according to applications of the storages. A plurality of address translation sections translate virtual addresses into real addresses, corresponding to the plural kinds of virtual spaces on the basis of the access information. A selection section selects any one of the plurality of address translation sections on the basis of the space identifying information. A transfer control section reads the data of the storage on the basis of the real address obtained by the selected address translation section and transfers the data to other processors together with the access information and the space identifying information.
