Consider an L1 cache with an access time of 1 ns and a hit ratio of H 0.95. Suppose that we can change the cache design (size of cache, cache organization) such that we increase H to 0.97, but increase access time to 1.5 ns. What conditions must be met for this change to result in improved performance?
plzz add more in this answer and correct the answer if wrong......
when we increase the hit ratio than the acces time is increased as given in the question..
i think we should use direct mapped cache...and we should increase the size of the cache as.. in direct cache we need address...to identify the particular word.....so it easy to get word in less time due to avalibility of address...
but if we use associative cache than there is no need of address and so we have to search throught the cache which wiill increase the cache accees time ..and performance will decreases.....
