Abstract: A system may include a processor and packet controller logic circuits implementing a distribution module, packet processing paths each including at least one configurable parsing engine and concatenating module pair, and an aggregation module. The distribution module can distribute an information unit between the plurality of packet processing paths. At least one of the packet processing paths can include multiple configurable parsing engine and concatenating module pairs coupled sequentially, and at least a portion of the information unit can be processed sequentially by the multiple configurable parsing engine and concatenating module pairs. The aggregation module can collect outputs from the packet processing paths.
