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.

   The HP Saturn processors, used in many Hewlett-Packard calculators between 1984 and 2003 (including the HP 48 series of scientific calculators) are "4-bit" (or hybrid 64-/4-bit) machines; as the Intel 4004 did, they string multiple 4-bit words together, e.g. to form a 20-bit memory address, and most of the registers are 64 bits wide, storing 16 ...

   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 ...
