Prоblem 3: Adder Design (16 pts) Cоnsider а 24-bit аdder design bаsed оn the Carry-Bypass architecture. PG is the logic unit to produce P and G. Assume the following delays for each 1-bit adder: tPG (delay to produce Pi and Gi signals from Ai and Bi) = 4 tcarry (delay to compute Cout,i from Pi, Gi and Cin,i) = 1 tsum (delay to compute Sumi from Pi, Gi and Cin,i) = 4 tmux (delay for the multiplexor) = 2 The registers are identical flip-flops (FFs) that are triggered by the rising edge of the clock: tC2Q (clock-to-Q delay of a one-bit FF) = 2 tsu (setup time of a one-bit FF) = 1 thold (hold time of a one-bit FF) = 1 For the entire problem, assume these delays are independent of the fan-in.    A. This 24-bit Carry-Bypass adder has 6 stages. Assume each stage has 4 bits. What is the minimum clock period in this 24-bit adder design? (4 pts)  (Hint: the first group carry propagates 3 bits after setup delay) [Write down and show how you get the answers on your solution papers.]   B. Starting from Bit-8, as highlighted in the figure above, what is the delay of the longest logic path? You don’t need to include input and output FFs. (3 pts) Delay =                           [Write down and show how you get the answers on your solution papers.]   C. There are many non-critical paths in the design of Part A, such as the path starting from Bit-4 or from Bit-8. We plan to improve the design by making these non-critical paths slower. The figure below presents a new design, in which the number of bits in each stage is now equal: 2, 4, 6, 6, 4, 2. What is the minimum clock period in this new design? (4 pts) [Write down and show how you get the answers on your solution papers.]   D. What is the delay of the longest logic path from Bit-6 to Bit-21, as highlighted in the figure? You don’t need to include input and output FFs. (3 pts) Delay =                            [Write down and show how you get the answers on your solution papers.]   E. What is the primary advantage of this new design, as compared to the design in Part A? (2 pts) Advantage =                              [Write down and show how you get the answers on your solution papers.]
