ABSTRACT:
After packets received by receiving latches have been divided into individual words and the words have been stored into buffer queues, the packets read from the buffer queues are stored into packet storage queues. A format determining circuit has defined in advance a plurality of types of writing formats and, when a packet is received by any of the receiving latches, determines dynamically a writing format according to availability of the buffer queues at this time. Then, a packet control circuit divides the received packets into individual words and stores the words into the buffer queues, according to the determined writing format.
