You want to build a circuit that would be able to detect the overflow in BCD addition i.e., if the result coming is either of 1010,1011,1100,1101,1110,1111? 0 0 replyShare lolalo commented Jul 15, 2022 i edited by lolalo Jul 16, 2022 reply Follow flag Like, if we add 0999(i.e, 0000 1001 1001 1001) which has 3 digits and a sign digit to 0999(itself), we should get 01998 which cannot be represented with 3 digits and a sign bit. I have an answer, let me know if you think the same. Overflow is detected in BCD addition, if the left-most digit i.e, the sign digit is not 0 or 9 after completion of the addition. 0 0 replyShare Please log in or register to add a comment.
