摘要
A search engine device includes a lookup circuit, such as a content addressable memory (CAM) array. This lookup circuit is configured to generate multiple active match signals in response to detecting multiple matches between a search operand applied to said lookup circuit and multiple entries therein, during a search operation. A priority sequencer circuit is also provided. This priority sequencer circuit, which is electrically coupled to outputs of the lookup circuit, is configured to sequentially encode each of the multiple active match signals according to priority.
