This repo contains the source code for the Rocksoft^tm Model CRC Algorithm.
For full details, see the Rocksoft/CRC_Explained.txt file.
For a short example on how to compute the CRC of some data using the Ethernet CRC-32 algorithm, see the crc-32.c file.
The crctable binary when executed will generate a crctable.out file that
can be used in your C/C++ code to compute fast table-driven checksums for
blocks of data.
By default, the table generated is for the Ethernet CRC-32 checksum. To generate a table for a different type of checksum (ex: different polynomial), modify the following defines at the top of crctable.c and rebuild:
#define TB_WIDTH 4
#define TB_POLY 0x04C11DB7L
#define TB_REVER TRUE
