ABSTRACT:
Methods and systems for a programmable filtering offset may include filtering desired data located at a variable offset from a start of a particular message in a data stream using a programmable hardware filter module. The variable offset may be specified in bits or bytes. The programmable hardware filter module may start filtering from an offset corresponding to the start of the desired data. The programmable hardware filter module may be a variable length filter or a fixed length filter. An offset from the start of a particular message may be determined, where the desired data that may be compared may start after the offset from the beginning of the message. The programmable hardware filter module may be configured with the determined offset.
