crc32
Hi All,

I got another question regarding to CRC
for CRC32: we have the poly:
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

Name : "CRC-32"
Width : 32
Poly : 04C11DB7
Init : FFFFFFFF
RefIn : True
RefOut : True
XorOut : FFFFFFFF

Now I know how to calculate the Poly, but what if we have a poly with an additional X31, would everything be the same except the poly?
x^32+x^31+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

Name : Non Standard
Width : 32
Poly : 0x84C11DB7
Init : FFFFFFFF
RefIn : True
RefOut : True
XorOut : FFFFFFFF

thanks for your help in advance.

Jim
