Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:
|
|
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.
|
|
|
|
Polynomials over GF(2) are represented in binary, one bit per coefficient,
|
|
with the lowest powers in the most significant bit. Then adding polynomials
|
|
is just exclusive-or, and multiplying a polynomial by x is a right shift by
|
|
one. If we call the above polynomial p, and represent a byte as the
|
|
polynomial q, also with the lowest power in the most significant bit (so the
|
|
byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
|
|
where a mod b means the remainder after dividing a by b.
|
|
|
|
This calculation is done using the shift-register method of multiplying and
|
|
taking the remainder. The register is initialized to zero, and for each
|
|
incoming bit, x^32 is added mod p to the register if the bit is a one (where
|
|
x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
|
|
x (which is shifting right by one and adding x^32 mod p if the bit shifted
|
|
out is a one). We start with the highest power (least significant bit) of
|
|
q and repeat for all eight bits of q.
|
|
|
|
The first (or only) table is simply the CRC of all possible eight bit values.
|
|
This is all the information needed to generate CRC's on data a byte-at-a-time
|
|
for all combinations of CRC register values and incoming bytes.
|
|
The remaining 3 tables (if IZ_CRCOPTIM_UNFOLDTBL is enabled) allow for
|
|
word-at-a-time CRC calculation, where a word is four bytes.
