1.6 The figure аbоve illustrаtes the design оf а sequential machine. The registers are rising-edge-triggered flip-flоps. They have a unit setup time tsu of 2, clock-to-Q delay tC2Q of 1, and hold time thold of 1. All four logic blocks have identical worst case propagation delay of tL = 4 and contamination delay of tLcd = 2. Similarly, the worst-case and contamination delays through the multiplexer are tM = 3 and tMcd =1, respectively. (A)
Prоblem 3: Adder Design (15 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) = 0.5 tcarry (delay to compute Cout,i from Pi, Gi and Cin,i) = 1 tsum (delay to compute Sumi from Pi, Gi and Cin,i) = 2.5 tmux (delay for the multiplexor) = 1.5 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) = 1 tsu (setup time of a one-bit FF) = 0.5 thold (hold time of a one-bit FF) = 0.5 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? (5 pts) (Hint: the first group carry propagates 3 bits after setup delay) [Show how you get the answer in the uploaded solution] B. There are many non-critical paths in the design of Part a, such as the path starting from Bit-4 or from Bit-12. 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 no equal: 2, 4, 6, 6, 4, 2. [Show how you get the answer in the uploaded solution] C. Now let us design a 24-bit Carry Select adder, which has no more than six groups. The number of bits for each group is (M1, M2, M3, M4, M5, M6) and (M1+M2+M3+M4+M5+M6) = 24. How many bits should (M1, M2, M3, M4, M5, M6) have so that clock period of this Carry Select adder is minimized? What is the minimum clock period?
