Abstract

PURPOSE:To prevent the scale of a converting circuit for binary-to-decimal conversion, etc., and its conversion time from increasing quickly even when the number of signal input terminals increases. CONSTITUTION:When a binary code 101110100111 is converted into a decimal number, 1+2+4+32+128+256+512+1048=2983 should be operated, but the addition of numbers of the low-order one digit is carried out by a comparing and counting circuit 1 and a counting circuit 9 shown at the right end of the figure, and a carry signal 14 is outputted to the 2nd counting circuit 9 from the left. Simultaneously, the 2nd comparing and counting circuit 1 and counting circuit 9 from the left are used to add the said carry signal 14 to the addition of only numbers of the 2nd digit from the least significant digit. Similarly, operations up to the most significant digit are performed and the decimal signal appears at the output 6 of the counting circuit 9.
