ABSTRACT:
A programmable arbiter providing for dynamic configuration of prioritization schemes is implemented using a simple, but effective structure. One or more arbiter banks are structured in a cascading manner. Each arbiter bank receives a predetermined number of the set of bus requests to be arbitrated. Each bank is separately programmed to provide a rotating or fixed priority scheme to evaluate the priority of the bus requests. Thus by separately programming the arbiter banks to operate in a fixed priority or rotating priority manner, a flexible, programmable arbiter is created which can operate according to a fixed, rotating or hybrid priority scheme and is adaptable to a variety of applications.
