PROBLEM TO BE SOLVED: To solve the problem that transfer efficiency is not easily improved by methods in a patent document 1 and a patent document 2 since transactions of a plurality of bus masters coexist on an interface and addresses do not easily become continuous, in a configuration that the plurality of bus masters access a bus slave through the same interface.SOLUTION: In a data transfer device for transferring data using packets including a header comprising a plurality of characters including an identifier indicating a kind of the packet, an address and transfer attribute information and data comprising a plurality of characters, transfer efficiency of a serial bus is improved by omitting a field of the address and the transfer attribute information inside the packet according to a result of comparison between information added to a bus transaction received by a serial interface and information registered beforehand. |
