Abstract
A bus bridge coupled between two bridges providing bus exception event isolation and address/data translation. In one embodiment the bus bridge includes two direct memory access (DMA) engines and a first-in-first-out (FIFO) buffer interface between the DMA engines to provide the bus exception isolation. The DMA engines and FIFOs also enable a packet based message passing architecture, which eliminates the need for address translation and also handles data reordering.
