Detailed Description

Static class for computing CRCs.

Note: This class supports computation of full and multi-part CRCs, using a bit-by-bit algorithm or a byte-by-byte lookup table. The CRCs are calculated using as many optimizations as is reasonable. If compiling with C++11, the constexpr keyword is used liberally so that many calculations are performed at compile-time instead of at runtime.

Note

This function allows for computation of multi-part CRCs

Calling UndoFinalize() followed by Finalize() (or vice versa) will always return the original remainder value:

CRCType x = ...;
CRCType y = Finalize(x, finalXOR, reflectOutput);
CRCType z = UndoFinalize(y, finalXOR, reflectOutput);
assert(x == z);

Parameters

[in]	crc	Reflected and XORed CRC
[in]	finalXOR	Final value XORed with the remainder
[in]	reflectOutput	true if the remainder is to be reflected

Template Parameters

CRCType	Integer type for storing the CRC result
CRCWidth	Number of bits in the CRC

Returns: Un-finalized CRC remainder
