Q An arithmetic and logic unit ALU performs integer and logic operations. Implement draw a minimized logic circuit the logic of a simple ALU that performs bit addition and subtraction. Assume the operands are and and the output is The control signal Op is only one bit, which selects addition or subtraction. Two ways to solve this. a Use bit adder half adder full adder with inputs to it being modified based on Op signal, or b start from a truth table. Then you may have to develop a truth table and use maps for variables leading to a large circuit. See next page for help. Recall that subtraction is done with adding after making the subtrahend negative s complement regardless of whether arguments are signed or unsigned.
