Abstract: This paper shows that even very small data caches, when split to
serve data streams exhibiting temporal and spatial localities, can improve
performance of embedded applications without consuming excessive silicon real
estate or power. It also shows that large block sizes or higher
set-associativities are unnecessary with split cache organizations. We use
benchmark programs from MiBench to show that our cache organization outperforms
other organizations in terms of miss rates, access times, energy consumption
and silicon area.
