Consider a 16-way set associative cache which holds 64 KB of data. The size of physical address is of 40 bits. A cache block consist of 4 words. Every data word is of 32 bits. Assuming that all cache entries are initially empty and data words are word-addressable. First-In-First-Out replacement policy is used for each set. At start-up the following physical addresses (in hexadecimal) are supplied to the cache in the sequence given below :
