A bus system is provided, which includes a shared resource, a shared bus, a plurality of requesters, and a bus arbiter for arbitrating access requests made by the plurality of requesters to access the shared resource through the shared bus. At least one of the plurality of requesters outputs, according to an internal state in that requester, an internal state signal indicating that the priority of an access request made by that requester needs to be changed. The bus arbiter arbitrates the access requests in accordance with the internal state signal.
