If an overflow is detected, the second adder is hardwired to add the value 6 (0110) to the output of the first adder which is equivalent to a subtraction of 10, thereby undoing the overflow of the first stage. The resulting 4 bit output value and 1 bit carry are the correct sum in BCD arithmetic.

If a carry results from this addition, add it to the next higher order BCD digit. Thus to implement BCD adder we require : 4 bit binary adder for initial addition; Logic circuit to detect sum greater than 9 and; One more 4 bit adder to add 01102 in the sum if sum is greater than 9 or carry is 1.
Implement single digit BCD adder using 4 bit binary adder ...
To implement BCD adder we require: • 4 bit binary adder for initial addition • Logic circuit to detect sum greater than 9 • One more 4 bit adder to add \$0110_{2}\$ in the sum if sum is greater than 9 or carry is 1 .

Digital Logic Design: BCD Adder
The two BCD digits, together with the input carry, are first added in the top 4 bit binary adder to produce the binary sum. The bottom 4 bit binary adder is used to add the correction factor to the binary result of the top binary adder.
