APPARATUS AND METHOD FOR PARALLEL CRC UNITS FOR VARIABLY-SIZED DATA FRAMES

摘要

A cyclic redundancy check (CRC) device configured to support parallel calculation of a CRC value for a data frame comprises a plurality of CRC processing units each configured to accept one of a plurality of data segments of the data frame of a variable size that can be unknown to the CRC device beforehand and generate one of plurality of partial CRC values in parallel with rest of the CRC processing units over multiple clock cycles/iterations. The CRC device further comprises an integration component configured to integrate the plurality of partial CRC values from the plurality of CRC processing units into one final CRC value for the data frame, wherein the final CRC value is attached to the data frame for error checking during storage or transmission of the data frame.
