Abstract
PURPOSE: To realize the buffer function enable to cope with the change in the state flexibly, by speeding up the data transfer speed, by providing the shift digit number selection means among a plurality of shift registers and changing the number of shift digits based on the control signal.
CONSTITUTION: When the control signal CNT1 is ON, the AND gates 2-1, 3-1, 4-1 are open, and the content of each register is shifted by one bit. When the control signal CNT2 is ON, the AND gates 2-2, 3-2, 4-2 are open and the content of each register is shifted by 2-bit. When the control signal CNT3 is ON, the AND gates 2-3, 3-3, 4-3 are open and the content of each register is shifted by 3-bit. Thus, since the number of shift digits can be changed for each shift register with the control signal, the number of shift ditits can be changed by the data transfer speed and one buffer can effectively be operated under various conditions.
