(a) A cache has the following parameters: b, block size given in numbers of words; S, number of sets; N, number of ways; and A, number of physical address bits. Provide an expression for the cache's byte capacity, C, in terms of the parameters provided Provide an expression for the total number of bits required for the tag storage array in terms of the parameters provided. Assume parameters S and b are powers of two. What are S and N for a fully associative cache of word capacity C with block size of b words? What is S and N for a direct mapped cache of word capacity C with block size of b words
