Consider two cache organizations. The first one if $64 \text{ KB}$ way associative with $64\text{ byte}$ block size. The second one is of the $64 \text{ KB}$ direct mapped cache. The size of an address is $32\text{bits}$ in both organizations. A $4$ to $1$ multiplexer has latency of $0.8\text{ ns}$ which $k \text{ bit}$ comparator has latency of $k/5\text{ nsec}$. The difference between the hit latencies of both cache organizations (i.e. associative hit latency - direct mapped hit latency) (in nsec) is ________ .
