1. A method for implementing Cyclic Redundancy Check (CRC) codes, comprising: performing at least one Boolean XOR operation for information bits input in parallel to obtain a first result; adding at least one pipeline for only the information bits during the XOR operation wherein a number of the added pipeline is determined according to a system performance condition comprising a clock frequency change; performing an XOR operation for a previously obtained CRC code to obtain a second result; and performing an XOR operation for the second result and the first result to obtain a current CRC code.
