Question

The time delay of 4-segment pipeline of Fig. 9-6 are as follows: t1=35 ns, t2=20 ns, t3=65 ns, and t4=35 ns. The interface registers delay time tr=5 ns.

1. Get the time to add 150 pairs.
2. If we managed to have a 2.5 times faster adder-sub tractor in stage-3 instead of the old one, then what would be speedup gained compared to part (a) to add 150 pairs.
