Abstract

A lookup-table type TL-TCAM hardware search engine includes a SL decoder, a TL-TCAM array, and the data stored in the TL-TCAM hardware search engine is obtained by performing lookup table operation in the corresponding TCAM hardware search engine, the SL decoder is used to decode the search word and send it to the TL-TCAM hardware search engine array, and the decoding is to convert a search word SL corresponding to data in a TCAM hardware search engine table into a search word LSL corresponding to TL-TCAM hardware search engine table data, the effect is that TCAM adds a decoder, cooperates with the decoder and by lookup table method converts the TCAM table data to a new circuit unit that can be adapted to the added search line.
