The master devices are coupled to core logic of the host IC via a crossbar switch and a bridge, which are part of the processor block core. The crossbar switch includes an arbiter. An arbitration protocol is selected from among a plurality of arbitration protocols for use by the arbiter. Pending transactions having are polled for access to the bridge for arbitration using the arbitration protocol selected.
