Question
Assume a 3GHz processor executes three classes of instructions
(A, B, C).
i. Calculate the average CPI for this sequence of
ii. Calculate the execution time for this sequence of program.
iii. If we use a system with four same processors, there will be
speed up by a factor of 4 for classes A and C, but class B will
remain unaffected. Calculate the new execution time for this
system. What is the overall speed up?
Class | A | B | C |
CPI for class | 4 | 2 | 10 |
IC in sequence | 100 | 200 | 300 |
