Given а dаtа cache with 4 blоcks each оf 4x32-­‐bit wоrds [or 1 cache block = 16 bytes = 4 memory words], what would the hit rate be for the cache when the following array accesses are made? Assume the cache is initially empty, that the processor operates on 32-­‐bit integers and has a byte-­addressable memory, and that the first element of array a is at address 0. (Please consider the data size of an integer datatype in C, C++, java, etc. i.e. 4 bytes for each array element) Hint: This is a multi-word direct map cache. Since 4 words can be stored in each cache block or index, when we miss out on some requested word, we load 4 words instead of just the one requested.  We are accessing elements of the array int a[20] and the accesses are as follows: a[0]; a[4]; a[12]; a[1]; a[0]; a[5]; a[13]; a[17]; a[0]; a[1]; [5 points] Fill in the following table to show how you came to the hit rate. Fill up the table to get 5 points and 1 point to give the hit rate. [1 point] Hit rate ?
