It represents the fundamental building block of the central processing unit cpu of a computer. In the above circuit a two input ex or gate two input and gate produces sum s carry c respectively. Therefore half adder performs the addition of two bits.
In computing an arithmetic logic unit alu is a combinational digital circuit that performs arithmetic and bitwise operations on integer binary numbers.
The most basic arithmetic operation is the addition of two binary digits. The arithmetic logic and shift circuits can be combined into one alu with common selection variables. Arithmetic operations expressed in 2s complement notation. I m going to delay showing you the interface diagram for the 32 bit full adder because we can modify it to also do subtraction.
