Abstract
An arbiter performs arbitration over a plurality of queues and provides data to a plurality of mutually exclusive destinations using combination logic that logically combines a plurality of mutually exclusive vectors into a combination vector. Each of the mutually exclusive vectors corresponds to one of the plurality of mutually exclusive destinations. A number of vector arbiters perform arbitration on each mutually exclusive vector to select a position within the mutually exclusive vector. A combination arbiter performs arbitration on the combination vector to determine a position within the combination vector, which corresponds to the next queue to be serviced. A comparison element compares the position within a mutually exclusive vector and the position within the combination vector to determine the destination of the data within the next queue to be serviced.
