Abstract

The described technology provides a method including receiving a request for allocating an incoming cacheline to one of a plurality of SFT entries in a snoop filter (SFT), performing a tag lookup function for a tag of the incoming cacheline in the SFT, in response to determining that the incoming cacheline is not part of an existing sector of any of the plurality of SFT entries, finding one or more candidate SFT entries, wherein the candidate SFT entries can be converted to an aggregated entry, selecting one of the candidate SFT entries, and allocating the incoming cacheline to the selected SFT entry.
