Abstract

A bus system comprises a master, a first slave, a second slave, and a bus. The master is configured to be able to issue a second request to the second slave after issuing a first request to the first slave and before receiving a response to the first request. The bus comprises: a determination unit configured to, upon receiving the second request, determine whether to permit a transfer of the second request to the second slave; and a suspending unit configured to suspend the transfer of the second request to the second slave while it is determined by the determination unit that the transfer is not permitted. The determination unit determines whether or not the transfer is permitted based on a notification from the first slave regarding processing of the first request.
