The skewed-associative cache achieves low miss rates with limited
associativity by using
inter-bank dispersion, the ability to disperse blocks over many
sets in one bank if they map to the same set in another bank.
This paper formally defines the degree of inter-bank dispersion and
argues that high inter-bank dispersion conflicts with common
micro-architectural designs in which the skewed-associative cache is
Various trade-offs for the skewed-associative cache are analyzed
and a skewed-associative cache organization with reduced complexity and a
near-optimal cache miss rate is proposed.
