Re: [ vuZs.net ] Attention its Emergency

Excuse me! Instruction Count is in millions in both questions, then y r u multiplying it in first Q while dividing in 2nd Q? In 2nd Q, its the part of formula but not in first Q. Isn't it?

Question No. 1:

 

Find the execution time for a program that executes 60 million instructions on a processor with an average CPI of 1.0 and a clock period of 33.3 nsec.

 

Solution:

 

Execution time = IC * CPI * T

IC = 60 * 10 ⁶

CPI = 1.0

T = 33.3 nsec  = 33.3 * 10^-9

Execution time = 60 * 10 ⁶ * 1.0 * 33.3 * 10^-9

= 1.998 Ans

 

Question No. 2:

 

Consider a program that executes 200 million instructions in 10 seconds. What is the MIPS rating for this program?

 

Solution:

 

MIPS = IC / ( ET * 10⁶ )

IC = 200 millions

ET = 10 sec

MIPS = 200 millions / (10 * 10⁶)

MIPS = 0.00002 Ans
