e) Let us consider a memory hierarchy (main memory + cache) given by: a. Memory size 1 Giga words of 16 bit (word addressed) b. Cache size 1 Mega words of 16 bit (word addressed) c. Cache block size 256 words of 16 bit d. Let us consider the following cache structures: i. direct mapped cache; ii. fully associative cache; iii. 2-way set-associative cache; iv. 4-way set-associative cache; v. 8-way set-associative cache. a) Calculate the structure of the addresses for the prenyous cache structures; b) Calculate the number of blocks for the previous cache structures; c) Calculate the number of sets for the previous set associative caches
