/* CRC computer using LFSR. |
E.g. Design a CRC-32 generator with the following polynomial (CRC-32 algorithm): |
G(x) = x^32 + x^26 + x^23 + x^22 + x^16 + x^12 + x^11 + x^10 |
+ x^8 + x^7 + x^5 + x^4 + x^2 + x^1 + 1 |
|
Equivalent to the following hex code: 0x04C11DB7, with the MSbit discarded (assumed |
present, but discarded in real implementation to save bits as it does not serve |
any other purpose). |
