Challenge Problems
Push your limits with challenges.
Question 1
Given a CPU clock speed of 3 GHz, calculate the cycle time and analyze the effective CPU Time using a base CPI of 1.5 with 25 memory stall cycles.
💡 Hint: Remember to convert GHz to its corresponding cycle time!
Question 2
Examine a scenario where a program’s memory miss rate is reduced from 15% to 5%. Calculate how this change impacts overall effective CPI given the same miss penalty and overhead.
💡 Hint: Consider how significantly even small percentages affect overall performance!
