Abstract
An arbitration protocol comprises the steps of receiving a plurality of resource request signals (12), comparing the received plurality of resource request signals to a rotating pointer (14), and either granting the shared resource to the resource user specified by the rotating pointer (16) and incrementing the rotating pointer (18) or granting the shared resource to a resource user according to fixed priority protocol (20, 22, 24, 26 and 28). The rotating pointer specifies one of a plurality of resource users according to a predetermined order. The two steps of granting are responsive to the step of comparing.
