<p>PROBLEM TO BE SOLVED: To achieve a pull transfer and transfer reception confirmation in a data pipe routing bridge. SOLUTION: In the network of digital signal processor nods which are connected in peer-to-peer relation, return transmission from a node is performed with a data packet sent to the node. A requester digital signal processor sends the data packet to a target digital signal processor (1001). After the data packet reaches the target digital signal processor, its receiver expels the arrival request packet into an I/O memory to trigger a transmitter interruption (1002). Then the transmitter executes a pull request packet (1003) on the next packet border by a pull interruption (1004). Lastly, the transmitter extracts part of a local I/O memory by the execution of the pull request and send it back to the requester digital signal processor (1007). At the same physical part of the I/O memory, two logical uses of a receiver channel and a transmitter code block are overlaid.</p> |
