Title: Speculative bus arbitrator and method of operation

Abstract: A bus interface unit for transferring data between a plurality of bus devices. The bus interface unit comprises: 1) a destination prediction circuit for predicting a predicted destination bus device associated with a first incoming bus access request received from a requesting one of the plurality of bus devices; 2) an arbitration circuit coupled to the destination prediction circuit and for arbitrating the first incoming bus access request based on the predicted destination bus device; and 3) an address determination circuit for calculating an actual destination bus device at least partially simultaneously with the arbitration of the first incoming bus access request and determining if the calculated actual destination bus device matches the predicted destination bus device.
