-----Cache Simulator---- https://github.com/kamalbec2005/CPU_Cache_Simulator.git
Writing code which meets functionality is a must. Optimizing the code to fit into less program memory and less number of cycles is experts job. Performance improvement makes the special place for your code. Cache hit/miss is one important among perforamnce metrics. We can use "perf" tool to measure the same, but.... it gives cache hit/miss against the same processor L1 cache size only. It is good if there is a tool which can simulate the cache size, maping model, replacing algorithm, memory block size, with prefetch/without prefetch. Here is the tool which can allow user to set the configuration of cache settings and get cache hit/miss metrics. Note: User has to collect the number of address locations to pass as input to the tool. "trace2.txt" is the input to the tool which has list of accessed address locations.
