6 pts Question 17 Consider an 8-bit ripple adder consisting of 8 full adders, each with a switching delay of 5 nano seconds. What is the total delay for this 8-bit ns. (You may assume a propagation delay of Ons) adder? If the 8-bit adder is redesigned with 4-bit ripple adders operating in parallel, what is the total delay for the new 8-bit adder, assuming that multiplexers used in this new design add 2 nano seconds? ns.(You may assume a propagation delay of Ons) What is the performance of the new design relative to the old design? (just enter it as fraction)
