An arbitration device includes an arbitration section, a counter, and a changing section. While write request signals and read request signals for a transfer path, are inputted from request sources, the arbitration section arbitrates an order that the write and read request signals use the transfer path, and when arbitration is settled, outputs use permission signals to the request sources. The changing section changes a time from outputting of the write request signals until inputting of the write request signals to the arbitration section, and/or a time from outputting of the use permission signals for the write request signals until inputting of the use permission signals to the request sources.
