Consider a 4-way set associative cache, with a capacity of 16 KiB and contains 512 cache lines. 32-bit byte addresses are used. What is the actual number of bits needed for this cache, assuming it is write-back? Include the necessary status bits (assume that 2 bits per cache line are required for this cache block replacement algorithm).
