Challenge Problems
Push your limits with challenges.
Question 1
Your CPU has a base CPI of 2 and a single cache miss penalty of 50 cycles along with a miss rate of 1%. Calculate the effective CPI if later an L2 cache is added with a miss rate of 0.5% at a penalty of 10 cycles.
💡 Hint: Break down the calculation for both L1 and L2 to see the overall impact.
Question 2
Explain how a 4-way set associative cache might improve hit rates compared to a direct mapped cache in specific conditions. Utilize relevant examples.
💡 Hint: Consider how data access patterns can interact with cache mapping types.
