Implementation of a Parallel CRC Calculation
Chen Yu-quan · Modern Electronic Technique · 2005
After having analyzed the principle of CRC calculation,this article introduces a fast parallel CRC calculation based on serial realization.This parallel calculation could easy deduce the logical relationship for 32 b parallel CRC.Comparing with Table Lookup Algorithm,it needn′t store the large remainder table,and decrease the delay.This parallel processing method is also fit for other bitwide CRC.Finally,using ISE platform and Verilog HDL,we have designed the 32 b CRC32 encoder based on this parallel calculation,its simulation and synthesis results are provided.The designed encode have been successfully used to the Ethernet system.
