Abstract
An arbitration protocol (68) comprises the steps of receiving a first (70) and a second (74) plurality of resource request signals, and either, granting the shared resource to a selected one of a first plurality of resource users (72) or granting the shared resource to a selected one of a second plurality of resource users (76). A differing one of each of a first plurality of resource users and of each of a second plurality of resource users generates a differing one of the first plurality of resource request signals and a differing one of the second plurality of resource request signals, respectively. Each one of the first and the second plurality of resource request signals corresponds to a first logic state if a particular one of the first or second plurality of resource users requests use of a shared resource. The shared resource is granted to a selected one of the first plurality of resource users according to a first arbitration protocol if at least one of the first plurality of resource request signals corresponds to the first logic state. The shared resource is granted to a selected one of the second plurality of resource users according to a second arbitration protocol if none of the first plurality of resource request signals corresponds to the first logic state and at least one of the second plurality of resource request signals corresponds to the first logic state.
