WebNSF Public Access WebAug 3, 2011 · In the replacement policy the most important factor is the number of associations (or ways). A direct map cache (1 way), directly correlates (all most always) with the low order bits of the address (the number of bits specify the size of the cache) so a 32k cache would be the lower 15bits. ravi phatak
