Abstract

PURPOSE: To make the storage capacity flexible between buffer devices according to the input data quantity, by providing the gate means capable of connecting mutually only a particular number of registers out of plural registers between buffer devices circularly.
CONSTITUTION: 1 is applied to input terminal x2 of AND gate 16 in buffer device 11 to turn gate 16 on, and 0 is applied to terminals x1, x3 and x4 to turn gates 15, 19 and 20 off. In buffer device 12, 1 is applied to terminal x1' to turn gate 22 on. When the data quantity transferred to device 11 exceeds the capacity of registers 14, 17 and 18, the output of register 18 is transferred to registers 24 and 25 through gate 22 of device 12. By applying 1 to terminal x3' to turn gate 26 on, data transferred to device 11 is sent from terminal O2 of device 12. Then, by turning gate 27 on, data transferred to device 12 and held in register 21 is sent from terminal O2.
