<p>In a relay device on an NoC, if every virtual channel is occupied with packets to be sent to the same destination, then packets to be sent to other destinations cannot pass through the relay device, thus deteriorating the packet transfer performance in terms of throughput and time delay. A relay device includes: an input buffer for receiving data units, each of which includes a header, to which multiple pieces of destination information have been added, and data associated with the header; multiple virtual channels for storing data units, each of the multiple virtual channels storing a data unit in accordance with the destination information; a destination comparing section for determining the order of allocation of virtual channels at a relay device on the receiving end with respect to the data units that are stored on the multiple virtual channels by seeing if their destinations are the same; and an output section for outputting the stored data units preferentially through one of the virtual channels that has already allocated at the relay device on the receiving end.</p> |
