The stage delays in a 4-stage pipeline are 800, 500, 400 and 300 picoseconds. The first stage (with delay 800 picoseconds) is replaced with a functionally equivalent design involving two stages with respective delays 600 and 350 picoseconds. The throughput increase of the pipeline is _______ percent.
[This Question was originally a Fill-in-the-Blanks question]
(A) 33 or 34
(B) 30 or 31
(C) 38 or 39
Throughput of 1st case T1: 1/max delay =1/800 Throughput of 2nd case T2: 1/max delay= 1/600 %age increase in throughput: (T2-T1)/T1 = ( (1/600) - (1/800) ) / (1/800) = 33.33%
