(b) In case the cache is direct-mapped cache, label the fields of the memory address below used to access the cache and indicate the name and size of each field in number of bits). Assume that memory is byte- addressed. _: __bits _: bits bits (c) In case the cache is 4-way set-associative cache, label the fields of the memory address below used to access the cache and indicate the name and size of each field in number of bits). Assume that memory is byte-addressed. __:_ bits : bits bits (d) In case the cache is fully-associative cache, label the fields of the memory address below used to access the cache and indicate the name and size of each field in number of bits).
