Abstract

PURPOSE: To reduce not only the number of data but the process time of the data transfer, by representing the data group of the continuous same pattern with a data plus the data showing the repeating frequency.
CONSTITUTION: The transfer data, when having the same pattern in a row, is stored in the registers 11 and 12. And the comparator 13 detects the coincidence. The result of the comparison is informed to the control part 14 and the counting circuit 15. And the circuit 13 performs the counting of once, and the part 14 transfers the data of the register 12 just once to the connecting device. After this, the transfer of data is discontinued until the circuit 13 detects the disagreement. The data of different patterns is received and stored in the register 11, and the control part 14 makes the selecting circuit 16 select the count value of the circuit 15 after receiving the information of the disagreement detection of the circuit 13. And the selected count value is informed to the interface circuit 17, and at the same time the signal showing that the data of the output line (f) is the count value is sent to the signal line (g) to be then transmitted to the connecting device.
