Abstract
A search engine device that supports a Patricia trie arrangement of search keys includes an array of comparator cells that supports parallel decoding of the Patricia trie. This array of comparator cells processes a plurality of distinguishing bit identifiers for nodes in the Patricia trie in parallel with a corresponding plurality of bits of an applied search key during a search operation. In response to this processing, the array generates a match signal that identifies a location of a matching search key candidate within the Patricia trie.
