Abstract:
1. A method of modifying a data stream in an integrated circuit (“IC”), comprising: compiling a hardware definition of a data stream modification circuit in the IC from a textual packet processing language specification of the data stream modification circuit, the textual packet processing language specification including a modification type, a modification point including a word offset portion and an offset within a word portion, a modification data length, and a bitwidth of the data stream; wherein the compiling includes determining a modification point in the data stream from a beginning of the data stream, the modification point having an offset within a word of the data stream; configuring the integrated circuit with a machine that implements the data stream modification circuit in the IC; and modifying the data stream with modification data by the machine that implements the data stream modification circuit at the modification point to produce a second data stream in the IC.
