Exploring the performance of split data cache schemes on superscalar processors and symmetric multiprocessors

The obtained results show that (i) in the superscalar processor the split data caches perform similarly or better than larger conventional caches, (ii) some splitting schemes work well in multiprocessors while others work less well because of data localities, (iii) the reuse information that some split schemes incorporate for managing is also useful for designing new competitive protocols to boost performance in multiprocessors, (iv) the filter data cache achieves the best performance in both scenarios.
