Design of an Arithmetic Logic Unit $($ALU$)$ projectObjectives: Our objective is to design an $8-$bit ALUAn arithmetic unit that can perform the following arithmetic operations: Subtraction with borrow Subtraction Addition Addition with carry Decrement Increment Transfer functionA logic unit that can perform the following logic operations: Logical OR Logical AND Logical XOR Logical NOT operation. Shift right Shift leftThe ALU circuit provides eight arithmetic operation, four logic operations, and twoshift operations. Each operation is selected with the five variables S$3,$ S$2,$ S$1,$ S$0,$ andCin. The input carry Cin is used for selecting an arithmetic operation only.Function of ALU
