ABSTRACT:
A hierarchical round robin arbiter includes a first set of arbitration vectors, each associated with a plurality of requesters. A second arbitration vector includes one bit for each arbitration vector in the first set. The single bit informs the round robin arbiter if any of the requesters associated with the corresponding arbitration vector in the first set are requesting service. The round robin arbiter can determine whether one of a number of requesters is requesting service by examining the single bit in the arbitration vector.
