    摘要: A bus bridging method, a bus bridge and a bus agent are described. In a bus agent provides to a bus bridge a read data request targeting a data source bridged by the bus bridge. The read data request includes a read address indicating a starting storage location of the requested data, and a read size indicator indicating the size of the requested data. The bus bridge, in response, facilitates provision of the requested data to the bus agent. The facilitation includes streaming buffered ones of the requested data to the bus agent through one or more successive streaming connections to the bus bridge by the bus agent.
