A method of a processor communicating data across a bus bridge to a processing apparatus on a bus including the steps of storing the data into a processor memory, notifying the bus bridge, coupled to the processor and a bus, that the data is in the processor memory, reading the data from the processor memory upon request of the bus bridge, and forwarding the data from the bus bridge to the processing apparatus across the bus. In addition, an apparatus for a processor to communicate data across a bus bridge to a processing means on a bus including an apparatus for storing the data into a processor memory, an apparatus for notifying the bus bridge, coupled to the processor and a bus, that the data is in the processor memory, an apparatus for reading the data from the processor memory upon request of the bus bridge, and an apparatus for forwarding the data from the bus bridge to the processing apparatus across the bus. |
