Abstract
A logic system maintains current least recently used information among the elements of each group in a plurality of groups where each group includes two or more elements. A memory stores intermediate information regarding the relative precedence between each combination of elements in a given group. A logic network recomputes this value each time an element in a group is used and provides this new information to the memory and to a network which resolves the current least recently used status.
