<p>PURPOSE: To obtain a circuit having a little power consumption by reducing the shift operations of a shift memory to be used in a data queueing as many as possible, in the data queuing device in a cell exchange device. CONSTITUTION: Each register R1, R2 and R3 of the queue 900 within a data queueing device is provided with each of selector S1, S2 and S3. The inputs of an external input 200 in all the registers are enabled. A register selection part 100 is capable of inputting the external input in an arbitrary register by selecting the register after the last end of data and switching the selectors.</p> |
