Abstract
In a centrally controlled resource arbitration system, each of the units concurrently requesting access sends its identity code and the binary complement thereof to a central arbitration processor. The identity codes are logically combined into a first word, and the binary complements are logically combined into a second word. A subset identifier of the requesting units is then formed by combining corresponding bits of the first and second words. Unresolved values in the subset identifier are iteratively removed to eliminate a subset of the requesting units. When all but one of the requesting units have been eliminated, access to the resource is given to the remaining unit.
