Abstract
A content-addressable memory is comprised of processing logic and selector logic. The processing logic receives a first selector including packet header information from the packet processing circuitry. The processing logic transfers the first selector to the selector logic. The processing logic generates additional selectors and transfers the additional selectors to the selector logic. The selector logic receives and processes selectors for matches and provides results corresponding to the matches. The processing logic receives the results from the selector logic and transfers at least some of the results that point to packet processing context structures to the packet processing circuitry.
