ABSTRACT:
A bus controller controls access to a processor bus by arbitrating between bus requests received from a plurality of bus requesters. The bus controller employs a pipelining arbitration mechanism in which a first bus requests from each bus requester is buffered to allow each bus requester to begin producing a second bus request before one of the first bus requests is selected by arbitration. As such, the bus controller performs arbitration between the first bus requests in parallel with the generation of the second bus requests by the bus requesters. The parallel pipelining approach enables the bus controller to base its arbitration decision on plural bus requests from each bus requester. The bus controller can select two bus requests from a first bus requester before selecting any of the bus requests from the other bus requesters.
