A cyclic redundancy check (CRC) system includes an input unit, a plurality of CRC engines for 1 byte to n/2 byte, and an output unit. The input unit has a data de-multiplexer for receiving n byte data. The plurality of CRC engines for 1 byte to n/2 byte are connected to the data de-multiplexer for processing demultiplexed n byte data. The output unit has a data multiplexer for providing processed CRC output data. The plurality of CRC engines for 1 byte to n/2 byte are arranged in two columns. A first column includes one or more CRC engines for 1 byte to n/2 byte and a second column includes a CRC engine for n/2 byte.
