Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A CPU with a 32KB L1 cache experiences a hit rate of 90%. If the all memory access time is 200 ns, calculate the effective access time if each cache hit takes 2 ns.

💡 Hint: Break down the formula using given rates and times.

Challenge 2 Hard

Discuss the trade-offs between increasing cache size and maintaining hit rates versus incorporating additional cache levels (L2, L3).

💡 Hint: Consider the implications of access speed versus data storage.
