Summary:The present invention has been conceived in view of the above described situation, and an object of the invention is to provide an information processing device, data transfer method and information storage medium that can commence data transfer to an I/O device immediately, and can stably exhibit data transfer performance. In an information processing device provided with hardware for sharing an address translation table, for translating logical addresses of a memory to physical addresses, between a main processor and a sub-processor, one of the sub-processors is caused to function as means for receiving a transfer request designating a logical address of the memory, means for translating the logical address that has been designated in the transfer request to a physical address using the shared address translation table, and means for executing transfer processing for data stored in the memory according to the translated physical address.
