  • Optimized high-level data link control encoding/decoding
    Patent number: 6785299
    Abstract: A system and method are provided for encoding and decoding a bitstream according to the High level Data Link Control protocol (HDLC) without having to analyze the bitstream bit by bit. An optimized encoder and an optimized decoder are provided. Both encoder and decoder analyze their respective input streams by using a number of bits in parallel as an index into a table, the contents of which control an action by the encoder or decoder that emits in parallel a number of output bits.
