ITPEC FE Morning October 2022 — Question 12 of 80
MIPS Calculation — convert nanosecond execution time to MIPS.
Formula: MIPS = 1 / (average instruction time in μs)
Step-by-step:
- Average instruction time = 20 ns = 0.02 μs
- MIPS = 1 / 0.02 = 50
Why not others:
- (a) 5 — divides by 200 μs instead of 0.02 μs
- (b) 10 — incorrect unit conversion
- (c) 20 — confuses the raw nanosecond value with MIPS
Key rule: 1 μs = 1000 ns. Convert ns → μs first, then apply MIPS = 1 / time_in_μs.
