A survey of dual data cache systems

Dual data cache (DDC) systems have attracted considerable research effort in the past decade or so, with their Divide et Impera tactic. DDC systems divide data according to their access patterns and use different caching strategies on them. In the first part of this paper, one possible classification taxonomy, is proposed and described. The second part of this paper represents a survey of the existing solutions classified according to proposed criteria, presenting their organization, benefits, shortcomings, and intended use.
