ABSTRACT:
A first device is operable to communicate on an bus according to a first protocol. A bridge is also operable to communicate on the bus according to the first protocol. A second device is coupled to the bus via the bridge and operable to communicate according to a second protocol. The bridge has a memory for holding data received from the second device and is operable to translate from the second to the first protocol. The second device sends write data responsive to receiving a ready signal from the bridge, and includes memory for holding the write data that the second device has sent, but for which completion has not been signaled. The second device re-sends the write data from the memory responsive to receiving a non-completion signal via the bridge, and releases the memory for the data responsive to receiving a completion signal via the bridge.
