Q 12-13 Common data ch-5 Ca
Consider two cache organization: the first one is 32 kB 2-way set associative with 32 B block size. The second one is of the same size but direct mapped. The size of an address is 32 bit in both cases. A 2 to 1 multiplexer has latency of 0.6 ns while a k-bit ... = 2.4 ns For 13. Op-d Only comparator latency =k/10 =17/10 = 1.7 ns Am i doing any thing wrong???
