0 votes 0 votes in this question how we can know set associativity. Consider two cache organizations. The first one if 64 KB way associative with 64 byte block size. The second one is of the 64 KB direct mapped cache. The size of an address is 32 bits in both organizations. A 4 to 1 multiplexer has latency of 0.8 ns which k bit comparator has latency of k/5 nsec. The difference between the hit latencies of both cache organizations (i.e. associative hit latency – direct mapped hit latency) (in nsec) is ___________. tiger asked Dec 20, 2015 tiger 1.1k views answer comment Share Follow See all 0 reply Please log in or register to add a comment.
Best answer 0 votes 0 votes as per given 4:1 mux,if we consider it is 4 way associative then answer is 1.2 ns. resuscitate answered Dec 20, 2015 • selected Dec 20, 2015 by tiger resuscitate comment Share Follow See all 0 reply Please log in or register to add a comment.
1 votes 1 votes There will be something n way set associative,else we can't determine set offset.The qs seems wrong.. resuscitate answered Dec 20, 2015 resuscitate comment Share Follow See all 3 Comments See all 3 3 Comments reply Sandeep Singh commented Dec 20, 2015 reply Follow Share Since it has given 4:1 multiplexure means we are going to use it for selecting one line out of 4 line of a set in cache. So its actually 4 way set associative. 0 votes 0 votes resuscitate commented Dec 20, 2015 reply Follow Share are u sure???then i am posting answer of it. 0 votes 0 votes Sandeep Singh commented Dec 20, 2015 reply Follow Share Yes. 1 votes 1 votes Please log in or register to add a comment.
