CRC32¶

Overview¶

A cyclic redundancy check (CRC) is an error-detecting code commonly which encode messages by adding a fixed-length check value, for the purpose of error detection. CRC32 is a 32bit CRC code. More details in Wiki CRC.

Implementation on FPGA¶

For the CRC32 design, it can be specified as:

Width : 32
Poly : 0xEDB88320 (crc32) or 0x82F63B78 (crc32c)
Init : 0xFFFFFFFF
Way : Lookup table
