摘要: A bus bridge (400) between two buses includes request queues: outbound (420) and inbound (430). Requests originating on the first (401) which target a destination second (402) are placed into queue (420). transaction arbitration unit, or TAU (418), within maintains ordering avoids deadlocks. The (418) also determines whether requests can be in inboud (430), responded to immediately must wait for reply, teh executed (402), posting (430) is enabled, posted transactions exist ownership of available.
