Challenge Problems
Push your limits with challenges.
Question 1
If a CPU processes 100 million instructions with a base CPI of 1.2 but experiences a 15% miss rate with a 100-cycle miss penalty, calculate the overall effective CPI.
💡 Hint: Remember to convert percentages to decimals before multiplication.
Question 2
In a system with a page fault rate of 0.01 and a miss penalty of 40 milliseconds, determine the average memory access time given a hit time of 200 nanoseconds.
💡 Hint: Use unit conversions for milliseconds to nanoseconds to keep consistent in your calculations.
