Abstract

An apparatus for correlating an unknown word with a plurality of dictionaryords includes a first memory area storing data corresponding to the unknown word and a plurality of second memory areas respectively storing data corresponding to the plurality of dictionary words. A control mechanism coupled to the first and second memory areas divides the unknown word into a plurality of unknown word fragments and divides each of the plurality of dictionary words stored in the second memory areas into a plurality of dictionary word fragments. An arithmetic logic unit compares the unknown word fragments to the dictionary word fragments and generates an output signal indicating a hit when an unknown word fragment corresponds to at least one of the dictionary word fragments. A hit counter counts the number of hits. The first memory area and the plurality of second memory areas may be implemented using circular shift registers.
