Creating a 6 bit crc using boost

I'm new to CRCs, boost and more of a java developer for that matter. I'm trying to use the the crc.hpp boost library to create a 6 bit crc calculated based on only two bits. First is this possible?

It seems that the Theoretical CRC Computer can be used to process a specific number of bits, however I'm unclear how to specify a 6 bit result. Help please.

Solution

  • Assuming your input is based on 2 actual bits and not two bytes, this should work:

    const int initial_remainder = 0xBAADF00D;

unsigned char input = 0x3;

boost::crc_basic<6> checksum(initial_remainder);
checksum.process_bits(input, 2);

printf("%i", checksum.checksum());

    You still need to figure out what the initial remainder should be, though.
