Abstract
The packet processor system has a port for receiving packets from a first network. A line interface unit is connected to the port for determining the types of packets that are received by the port. A generic pipeline stage assembly is connected to the line interface unit and includes a plurality of generic pipeline stages each having a request engine for sending lookup requests to a lookup engine and a modifier engine for receiving lookup results from the lookup engine. A packet memory is connected to a last generic pipeline stage of the generic pipeline stage assembly and an output line interface unit is connected to the packet memory and a second network.
