PROBLEM TO BE SOLVED: To output an inputted cell while providing desired delay fluctuation by controlling the read timing of an output cell outputted from a delay buffer corresponding to section signals for indicating the start and end of a delay amount. SOLUTION: A delay object cell 11 to be a delay addition object is written in the delay buffer 1 by the write signals 12a of a read/write control circuit 4 and simultaneously, a delay amount monitoring counter 2 is counted up by the write signals 12a. Also, the delay amount counter 2 is counted down by read signals 12b and the delay amount and a counter value are matched. A section counter 5 outputs sections for indicating the start and the end of each delay amount set in a comparator circuit 3 to the read/write control circuit 4. Then, the read/write control circuit 4 controls the read timing of the cell outputted from the delay buffer 1 corresponding to detection signals 13 from the comparator circuit 3 and the section signals 14 for indicating the start and end of the delay amount from the section counter 5. |
