In the design of a new ALU of a new AMD microprocessor, a $2-$bit wide logical unit was proposed that compares any two $2-$bit data fetched from the RAM. Whenever the $2-$bit data fetched are of equal magnitude, they are required to be multiplied, whenever the first $2-$bit fetched has a higher magnitude than the second one, the two arguments are subtracted, and whenever the first $2-$bit data fetched has a lesser magnitude compared to the second one, both arguments are added. The chip engineers are considering using a pre$-$designed combinational logic circuit to accomplish this computational task. You are required to design a suitable combinational logic circuit that would perform the desired operation of the new ALU. All required truth tables, logic equations, and logic circuit diagrams must be clearly shown?
