Webb30 jan. 2024 · In its most basic terms, the data flows from the RAM to the L3 cache, then the L2, and finally, L1. When the processor is looking for data to carry out an operation, it first tries to find it in the L1 cache. If the CPU finds it, the condition is called a cache hit. It then proceeds to find it in L2 and then L3. WebbMemory hierarchy: Let us assume a 2-way set associative 128 KB L1 cache with LRU replacement policy.
