Synchronous protocol encoding and decoding method

摘要: A method to encode and decode frames of data used in synchronous protocols, including HDLC SDLC. The invention operates on blocks data, such as bytes or words, a parallel rather than bit serial manner. compares an aligned block with reference sequences for flag abort signal detection, zero deletion, detection consecutive one bits, insertion following stream encoding decoding according various protocols. also maintains proper alignment insertions deletions, provides under both overrun underrun conditions.
