Simple cache simulator built using Java. This will further your understanding of cache basics and strengthen your C programming skills. /test-trans -M 32 -N 32 linux> . cpp now just creates the simulator and calls run. This makes sense since a fully associative cache is the one that will have the least cache misses because if we want to cache the data in memory locations with the same index, we do not need to evict as long as there is still space in the cache. py ├── cpu. ) to determine the degree of throughput, fairness or other relevant metrics for a workload under a The operation field denotes the type of memory access: “I” denotes an instruction load, “L” a data load, “S” a data store, and “M” a data modify (i.
