A compound control/data channel connects an I/O bridge (IOB) and a data buffer unit (DBU) in a high performance I/O subsystem. Generally, data movements among an I/O bridge, data buffer unit, system bus and I/O bus are dominated by separate control signal groups issued from the I/O bridge. The compound control/data channel permits integration of these control signal groups onto the data channel connected between I/O bridge and data buffer unit. A data controller can control and transfer data to/from a data buffer using this unique channel, alternately, for control information and data streams.
