<p>PROBLEM TO BE SOLVED: To provide the control method in which a transmission efficiency is improved in the case of adopting a burst memory for a buffer memory. SOLUTION: A logic queue group 31 consisting of a plurality of logic queues 301 -30k is provided in a buffer memory 13. When a write request of an input cell and a read request of stored cells to any of a plurality of the logic queues 301 -30k are caused simultaneously, a cell read section 14 reads the stored cell from, e.g. the logic queue 30k and a bank of the logic queue 301 for the read cell is bypasses as shown in a caption 82 in figure, and an input cell is written to the bank by a cell write section 12. That is, the cell is read from and an input cell is written to the same bank by the bypass 82.</p> |
