Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You have a cache system with a hit time of 4 ns, a miss penalty of 40 ns, and the cache experiences 120 hits and 80 misses out of 200 total accesses. Calculate the AMAT.

💡 Hint: Use the formula: AMAT = Hit Time + (Miss Rate × Miss Penalty).

Challenge 2 Hard

If a system has a hit rate of 0.85 and a corresponding miss rate of 0.15, and you know the miss penalty is 50 ns, calculate the impact on AMAT if the hit time is 5 ns.

💡 Hint: Remember how miss rate and hit time factor into the AMAT.
