Abstract
A method for pipeline arbitration including receiving a first request for a shared chip interface from a first pipeline, determining whether a response bus of the shared chip interface is needed by the first request, and if it is determined that the response bus is not needed by the first request, concluding that the first request needs just an address bus of the shared chip interface, arbitrating the first request with a second request for the shared chip interface received from a second pipeline for access to the address bus, sending the first request to the address bus if the first request wins the arbitration over the second request, and rejecting the first request if the second request wins the arbitration over the first request.
