Introduction to Computer Systems - Fundamentals of Computer Organization and Architecture - page 14

Assume that the machine's clock rate is 500 MHz. Which code sequence will
execute faster according to MIPS? And according to execution time?
10. Three enhancements with the following speedups are proposed for a new
machine: Speedup(a)

15.
Assume that for some set of programs, the fraction of use is 25% for
enhancement (a), 30% for enhancement (b), and 45% for enhancement (c).
If only one enhancement can be implemented, which should be chosen to
maximize the speedup? If two enhancements can be implemented, which
should be chosen, to maximize the speedup?

30, Speedup(b) 20, and Speedup(c)
