Abstract

Memory deduplication, which can remedy memory scarcity in mobile systems, can hardly be used due to its high computation cost. This paper proposes a computation efficient memory deduplication scheme that avoids unnecessary computations for memory deduplication. To make it efficient, the proposed scheme gets rid of pages, which are unlikely to be deduplicated, from the target of memory deduplication. This exclusion is performed in time-domain and in space-domain by exploiting the characteristics of mobile applications. The prototype implementation shows significant computation cost reduction while providing the same memory savings as in previous approaches. The saved memory is used for improving application launch time as well.
