METHOD AND APPARATUS FOR PERFORMING CYCLIC REDUNDANCY CHECK FOR DATA PACKETS

摘要

The present invention discloses a method and an apparatus for performing Cyclic Redundancy Check (CRC) for data packets, which relate to the field of communications and are used for solving the problem of occupying Random Access Memory (RAM) access bandwidths when CRC is performed for data packets. The method provided by the present invention includes: receiving the packet information of a data packet for which reordering and recombination have been completed, wherein the packet information includes the Identification (ID) of the data packet; according to the packet information of the data packet, obtaining the CRC value of each fragment in the data packet, the length of each fragment, and the order of each fragment in the data packet; and according to the CRC value of each fragment, the length of each fragment, and the order of each fragment in the data packet, calculating and obtaining the CRC value of the data packet. The present invention is applicable in the field of communications and is used for performing CRC for data packets.
