WebbSkewed Compressed Cache (SCC) [Sardashti et al. 2014] also uses super-block tags, but eliminates the area of DCC’s backward pointers using a skewed-associative lookup [Seznec. 1993; Seznec. 2004.] and direct tag-data mapping. SCC also simplifies cache replacement by always replacing an entire super-block, rather than individual blocks.

A case for two-way skewed-associative caches*

WebbA set associative cache can be seen as a skewed associative cache whose skewing function maps to the same value for every way. Skewed Associative. The skewed associative indexing policy has a variable mapping based on a hash function, so a value x can be mapped to different sets, based on the way being used. Webb27 jan. 2024 · For PhantomCache, however, GEM and SHM yielded better eviction rates as the found eviction set makes up roughly 50% of the cache. As skewed caches exhibit a significantly smaller probability of successful eviction (e.g., 2-4% for ScatterCache), eviction sets might be chosen larger to obtain high eviction probabilities and and …
