WebHi guys, I'm writing an ALU in verilog and need to program when to turn on/off the carry flag in the addition /subtraction operations. Do any of you know how to determine if given a sum of two binary numbers, e.g. 32bits each, the result will produce a carry? WebJul 1, 2024 · There are four digits in the inputs, so we need four steps. For each step, we shift the left-most digit of the dividend A into ACC, then compare it with the divisor B. If ACC is greater or equal to B, then we subtract B from ACC and add 1 to the quotient QUO. This is easiest to see by working through the example: in business letter format
