We have a standard 32-bit byte-addressed MIPS machine with 4 GiB RAM, a 4-way set-associative CPU data cache that uses 32 byte blocks, a LRU replacement policy, and has a total capacity of 16 KiB. Consider the following C code and answer the questions below. (size of int type variable is 4 byte)

We call count_x with all values of x from 0 to 65535 to count the number of times that each x occurs in A. The value of A is the same in every call. The cache is cold at the beginning of execution. What is the cache hit rate?(answer in percentage with % sign, eg 10%)
