64-bit ripple-carry adder and a 64-bit carrylookahead adder with 4-bit blocks. Use only two-input gates. Each two-input gate is 15μm2, has a 50 ps delay, and has 20 pF of total gate capacitance. You may assume that the static power is negligible.
(a) Compare the area, delay, and power of the adders (operating at 100 MHz).
(b) Discuss the trade-offs between power, area, and delay.
