WebApr 13, 2024 · A subtractor would be the same circuit as an adder by representing a negative number as two’s complement. In short, subtraction is thought of as “adding a negative number.” For example, if you want to calculate 7–5, you can think of it as 7+(–5). To turn a binary number into two’s complement, “flip the bits and add 1.” WebIn the above attached image the ALU is 1 Bit and only can perform Full Addition, Full Subtraction, NAND and NOR operation. Full Adder: A full Adder is a Combinational Circuit which can take 3 inputs at a time and show the addition result. The addition results are labelled as SUM and CARRY. A full adder is a cascade connection of 2 half adders.
