Abstract

PURPOSE: To carry out the data transmission smoothly and efficiently by selecting the required data in parallel with the movement of the data, thereby, removing the unnecessary data and selecting the necessary data.
CONSTITUTION: To the data buffer portions 101W401, the control bit portions 102W402 for displaying the necessary or unnecessary data stored to form the respective data buffers 1W4. To this bit portions 102W402 the signal of the display lines 11W14 and OR circuit 20W22 taking OR of the preceding step bit portions 202W 402 are connected. In addition, OR circuit taking OR of the strobe signal 16 every time the data is taken out from the buffers 1W4, and OR circuits 15W17 taking OR of the output of the preceding step circuits 14W16 every buffer and the outputted data are connected to take out OR of the outputs of the respective circuits 14W17 and the clock signal 5 in the AND gate 29W30, give the shift clock signals 7W 10 to the buffers 1W4 and select the necessary or unnecessary data.
