WebFor the chosen cache configuration we see that the line index of the cache is the following bitmask: 0b0000001 11110000. Applying the bitmask to the access pattern listed above, we see that all access addresses mask to 0x0 and thus will index to the same cache line. In other words, we have no diversity with respect to the indexing in the cache for the given … WebThe above pattern accesses memory in strides: for example, thread 1 accesses a, then e, then i etc. This maximizes cache locality per unit time.
