Draw a complete 4 x 4 multiplier that takes two fourbit numbers (call the input bits A3 … A0 and B3 … B0), and which outputs an 8bit result (M7 … M0). Use a carrysave architecture for this, use as little hardware as possible, and assume that the numbers are unsigned : 2. Is there any way to use an architecture like this for signed numbers? Give short explanation....
