Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a hit rate of 85% and a miss penalty of 150 ns, calculate the AMAT when the hit time is 2 ns. Discuss how this AMAT compares to a scenario with a 70% hit rate.

💡 Hint: You may want to first calculate the AMAT under both scenarios for a complete comparison.

Challenge 2 Hard

Assume you are designing a new CPU. If you want to achieve an ideal AMAT under 10 ns, what strategies could you implement to improve hit rate or reduce miss penalty?

💡 Hint: Reflect on the importance of cache organization and access policies.
