2. [6 points] You have a system on which addresses are 36 bits long. For each of the following scenarios, determine the cache (data) capacity, number of cache blocks, the size (in bytes) of each cache block, the address bits used for the tag, index, and offset (each specified as [high order:low_order], inclusive, as we did in lecture), and the total amount and percentage of metadata overhead. Obviously, some parameters will be given in each example; you need to calculate the rest. Please include the given parameters in your list (a) 32 KB write-through D-cache with 16 byte blocks (b) 16 KB write-back D-cache with 256 blocks (c) 64 KB I-cache with 5 index bits (d) Unknown size write-through D-cache with 21 bit tags and 8 byte blocks
