Push your limits with advanced challenges

Challenge 1 Hard

How does adding more cache affect system performance, considering page faults and TLB hits?

💡 Hint: Think about how often data is accessed and how caching helps memory retrieval.

Challenge 2 Hard

If a program runs with a page fault rate of 5% and each fault costs 200ms, calculate the average time taken for 1000 instructions assuming each instruction takes 10ms.

💡 Hint: Break down the problem into instruction time and fault handling time.
