Abstract: A system for performing a cascading search includes an associative memory array, a controller, a similarity search processor and an accuracy matching processor. The associative memory array stores a plurality of multiportion data vectors in at least one column of the associative memory array. Each vector has a first portion and a second portion which are aligned to each other in the column. The controller controls the associative memory array to perform a similarity search of a similarity query on the first portion and an accuracy search of an accuracy query on the second portion. A similarity matching processor generates a matching row including matching bit indications aligned with each similarity matched column. The matching row indicates columns having first portions which match to the similarity query. The accuracy matching processor outputs accuracy matching columns from among the similarity matched columns which have second portions which match the accuracy query. Therefore, the multi-step search within a memory becomes efficient.
