WebIn the hierarchical organisation all the levels of memory (cache as well as main memory) are connected sequentially i.e. the CPU can access L2 cache only if there is a miss in L1 cache. CPU -> L1 -> L2 -> Main Memory. In this case the first formula you mentioned is applicable as access of L2 starts only after L1 misses. WebThe L1 cache has a 1ns access latency and a 100 percent hit rate. It, therefore, takes our CPU 100 nanoseconds to perform this operation. Haswell-E die shot (click to zoom in). The repetitive...
