A 4-way associative write-back cache is implemented on a system with 32 bit words and addresses. It is organized with 4 words per block and has a total of 1024 blocks. Show how the address bits A[31] to A[0] would map to the tag, index, word offset, and byte offset fields. How many dirty bits are required? How many valid bits? How many tag bits? How many data bits? (List separately). What is the total memory?
