Abstract
The present invention relates to an error control technology in the communication system and discloses a method and an apparatus for implementing Cyclic Redundancy Check (CRC) codes to improve the operation performance of the system significantly and satisfy operation requirements when processing high-rate CRC data. The method includes: performing at least one XOR operation for information bits input in parallel to obtain a first result, where at least one pipeline is added during the XOR operation; 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. The present invention is applicable to any field that needs to implement CRC codes by means of hardware.
