How does cache affect the cpu

WebJan 13, 2024 · In a simple case the CPU would stall on load/store instruction or instruction fetch waiting for the bus to become inactive. However, since most CPUs have a cache between the main memory bus and the cores this is often avoided. If the access hits the cache then no access may go out onto the bus. WebJun 22, 2024 · AMAT = Hit Time + Miss Rate * Miss Penalty. What interests us is that the AMAT is low, since it measures the access time of the CPU to the data and therefore the latency when it comes to finding the data.
