Abstract
Some embodiments provide a method for a match-action stage of a packet processing pipeline. The method receives a set of data containers storing input packet data values for a particular packet. The set of data containers includes multiple subsets of data containers. The method performs a set of match operations using a first subset of the set of data containers. The method uses a set of arithmetic logic units (ALUs) to generate output packet data values to store in a second subset of the set of data containers. Output packet data values for a third subset of the data containers are generated without the set of ALUs.
