Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a system where the cache hit ratio is only 50%. Calculate the expected number of memory accesses if the CPU needs to retrieve 100 data items.

💡 Hint: Break down the 100 accesses into hits and misses based on the hit ratio.

Challenge 2 Hard

Explain how increasing the size of the cache might affect the miss ratio and give an example.

💡 Hint: Think about how storage capacity can change access efficiency.
