A) With a 32-bit address, how many total Tag bits are required for a direct-mapped cache with 256 bytes of data and 16-byte blocks? B) Give the block number to map byte address 0x0018 to, when we have a 16-block direct-mapped cache, with 16-byte blocks and Tag bits are the high order bits. C) Suppose we have a 2-Way Set Associative cache with 256 bytes of data, 16-byte blocks, and 32-bit physical address, instead of a direct-mapped cache. Fill in the address breakdown table for this cache with the following fields: Index, Tag, and Byte offset and their corresponding address bits
