build design an Arithmetic-Logic Unit with specifications

Input Width: 8 bits Output Width: 8 bits ALU Operations: ADD, OR, EOR, NOT, ADD, SUBTRACT,MULTIPLY, COMPARE

Status register that stores the following flags: Negative, Zero, Carry and OVerflow

Each ALU operation implemented by a sub-circuit constructed with individual logic gates. These sub-circuits should be put together in one device called ALU with appropriately named inputs and outputs.
