Design an ALU with three 8-bit inputs A, B and K, and single bit control inputs x, y and z. The ALU should support the operations described in the table below. Design of A + B and A - B: Use a single 8-bit adder and logic gates/muxes to implement the logic for both these operations. Design of A * 4 and A/8: Use a shifter and MUXes to implement both these operations. Design of polynomial function f = (AK^2 + BK) mod 256. 256 is (100000000)_2 and the modulus helps us handle overflow. You can use multipliers and only a single adder. Design of ALU: Use a 8: 1, 8-input MUX to implement the ALU described above. You can show the components designed in parts as black-boxes
