- A computer system has a main memory consisting of 2M 32-bit words. It also has an 8K-word cache organized in the block-set-associative manner, with 2 blocks per set and 128 words per block.a. Calculate the number of bits in each of the TAG, SET and WORD fields of the main memory address format.b. Assume that the cache is initially empty. Suppose that the processor fetches 2486 words from locations 0, 1, 2,…., 2485, in that order. It then repeats this fetch sequence 10 more times. If the cache is 5 times faster than the main memory, estimate the improvement factor resulting from the use of the cache.Assume that the LRU algorithm is used for block replacement.Suppose a byte-addressable computer using set associative cache has 224 bytes of main memory and a cache size of 64K bytes, and each cache block contains 32 bytes. a) If this cache is 2-way set associative, what is the format of a memory address as seen by the cache, that is, what are the sizes of the tag, set, and offset fields? b) If this cache is 4-way set associative, what is the format of a memory address as seen by the cache?Suppose a computer using fully associative cache has 224 bytes of byte-addressable main memory and a cache of 128 blocks, where each block contains 64 bytes.Q.)
