Abstract
The present invention provides for a plurality of partitioned ways of an associative cache. A pseudo-least recently used binary tree is provided, as is a way partition binary tree, and signals are derived from the way partition binary tree as a function of a mapped partition. Signals from the way partition binary tree and the pseudo-least recently used binary tree are combined. A cache line replacement signal is employable to select one way of a partition as a function of the pseudo-least recently used binary tree and the signals derived from the way partition binary tree.
