Question: Consider a 6 4 - byte size virtually indexed cache with 8 byte blocks, an associativity of 2 , write - back policy, and LRU

Consider a 64-byte size virtually indexed cache with 8 byte blocks, an associativity of 2, write-back policy, and LRU replacement. Virtual addresses are 16 bits. The physical memory is 16 KiB.
How many bits of the address is the block offset? bits
How many bits of the address is the index? bits
How many bits of the address is the tag? bits
How many bits are needed in hardware to implement the cache? bits
