2. Adder–subtractor - Wikipedia

   en.wikipedia.org/wiki/Adder–subtractor

   A 4-bit ripple-carry adder–subtractor based on a 4-bit adder that performs two's complement on A when D = 1 to yield S = B − A. Having an n-bit adder for A and B, then S = A + B. Then, assume the numbers are in two's complement. Then to perform B − A, two's complement theory says to invert each bit of A with a NOT gate then add one.

   Breaking this down into more specific terms, in order to build a 4-bit carry-bypass adder, 6 full adders would be needed. The input buses would be a 4-bit A and a 4-bit B, with a carry-in (CIN) signal. The output would be a 4-bit bus X and a carry-out signal (COUT). The first two full adders would add the first two bits together.

   4-bit adder with logical block diagram shown Decimal 4-digit ripple carry adder. FA = full adder, HA = half adder. It is possible to create a logical circuit using multiple full adders to add N-bit numbers. Each full adder inputs a , which is the of the previous adder. This kind of adder is called a ripple-carry adder (RCA), since each carry ...

9. Subtractor - Wikipedia

   en.wikipedia.org/wiki/Subtractor

   The full subtractor is a combinational circuit which is used to perform subtraction of three input bits: the minuend , subtrahend , and borrow in . The full subtractor generates two output bits: the difference D {\displaystyle D} and borrow out B out {\displaystyle B_{\text{out}}} .
