In superscalar process design

Store Vulnerability Window technique improves system performance by reduce load re-execute rate.In this paper

we present a novel design of load store queue with Enhanced SVW.We observe that if store sequence Bloom filter (SSBF) unit in SVW is modified to keep not only store sequence number (SSN) but also complete memory addresses and data values

trailing loads can get data from SSBF rather than cache

therefore data cache access rate will be further reduced.Experiments show that

in the best case

over 99%re-execute loads are kept from memory re-access

and system performance is improved by 2%.
