In a bus interface unit, a first communications interface is provided for the coupling of a first plurality of peripheral devices of different device types to facilitate communication with a selected one of the first plurality of peripheral devices of different device types. In addition, a second communications interface is provided for coupling to a first bus of an integrated circuit (IC) to facilitate communication with a selected one of a second plurality of devices of the IC, via the first bus. A controller is provided for the coupling of the first and second communications interfaces to facilitate communications between selected ones of the first and second plurality of devices, dynamically selecting and employing a communication protocol consistent with the device type of the selected one of the first plurality of peripheral devices. The bus interface unit has particular application to interfacing external devices with the core of an SOC.
