|発明の名称||K VICINITY METHOD ASSOCIATION MEMORY WHICH CAN BE RECONFIGURED|
PROBLEM TO BE SOLVED: To provide a k vicinity method association memory which can expand a dimension and a number of reference data.
SOLUTION: A k vicinity method association memory (100) which can be reconfigured comprises: a clock count type association memory (10) which can be reconfigured; and a k vicinity clustering circuit (30). The association memory (10) comprises: plural element circuits (70); and plural switch circuits (50) for optionally connecting the plural element circuits. Until some k pieces of match signals out of plural match signals output from the association memory (10) become an active state, the k vicinity clustering circuit (30) selects class data corresponding to each and at least one of the k pieces of match signals, which become the active state, from plural pieces of class data indicating classes of plural pieces of reference data, for every time that at least one of the plural match signals become the active state, and then determines a class in which a number of data becomes maximum, when the all k pieces of class data being selected, are classified for every class.
