ABSTRACT:
The data transfer between an initiator and a target, interconnected over an IEEE1394 interface, is to be improved in efficiency. At the time of login, the buffer information of the targets11to14is acquired by an initiator10. Based on the buffer information, acquired by the initiator10, a data transfer table, at least including the node ID information of the targets11to14, address information of the buffer memory and the data transmission/receipt specifying information for specifying the transmission or receipt of the data, is formulated. The data transfer table, formulated by the initiator, is supplied to each target. When a signal instructing the transfer of the data is input, handshaking is performed between the initiator10and the targets11to14, based on the predetermined information appended to the transfer protocol of the interface, to effect the data transfer based on the data transfer table.
