Open calculatorCache Average Memory Access Time Calculator is an educational computer-science tool for exploring a standard computing relationship.
Enter the requested values using the stated units. The calculator validates the numerical domain and applies AMAT = hit time + miss rate × miss penalty.
Variables: hit time = Cache hit time (ns); miss rate = Cache miss rate (%); miss penalty = Cache miss penalty (ns).
Example: hit time = 1 ns, miss rate = 5%, miss penalty = 100 ns → AMAT = 6 ns.
It is intended for study, classroom exercises and quick exploration of the stated computing relationship.
No. Real systems can include hardware, software, protocol, workload, caching, scheduling and implementation effects beyond the simplified model.
