1. An apparatus for detecting and correcting cyclic redundancy check (CRC) errors, comprising:

  • a first gate for switching an input data;

    a buffer register for receiving the input data and outputting the input data in parallel;

    a syndrome register section including a plurality of syndrome registers for forming redundancies for an output data of said first gate;

    an OR gate for receiving data from said syndrome register section to produce an enable signal;

    a decoder receiving said enable signal from said OR gate, said decoder for decoding said data from said syndrome register;

    a plurality of exclusive-OR (Ex-OR) gates for receiving outputs of said buffer register and said decoder and performing Ex-OR arithmetic operations; and

    a latching section for latching outputs of said Ex-OR gates.
