Abstract
PURPOSE: To carry out the input processing including verify rapidly by detecting the delay accommodated address of the keys struck, comparing the accommodating contents of the two data buffer and checking.
CONSTITUTION: Back line address select portion 14 selects the back line address of the addresses indicated by the write address indicating portions 12, 13 (writing delayed side write address) and indicates it to the read data portion 15, 16. This expects the nonalignment of the keyboards 1 and 2 since for example, the data W1 is written in the first address of the buffer 7 and the data W2 is written in the second address. Then, at this time, the write data which can be compared by the comparison data 17 is only R1, R2 of the first address. Then, the information analyzer portion 18 receives the output of the circuit 17 and if they do not coincide, the signal NG is fed to the error processing portion 19 as any key operating being error and if it is normal, the signal OK is fed to the buffer full check 20.
