GATE - 2004 [Operating System]

Question:

In an enhancement of a design of a CPU, the speed of a floating point unit has been increased by 20% and the speed of a fixed point unit has been increased by 10%. What is the overall speedup achieved if the ratio of the number of floating point operations to the number of fixed point operations is 2:3 and the floating point operation used to take twice the time taken by the fixed point operation in the original design?

A

1.155

B

1.185

C

1.255

D

1.285

Solution:

Option (A) is Correct.
