DUNE::Algorithms::CRC32 Class Reference

Detailed Description

CRC-32 Algorithm.

The polynomial used is 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 + 1 (0x04C11DB7)

static uint32_t DUNE::Algorithms::CRC32::compute ( const uint8_t *  buf, const uint8_t  len, bool  do_reflect, uint32_t  crc = 0  )

inlinestatic

Compute the CRC-32 of a given data buffer.

Parameters

buffer	data buffer.
len	data buffer length.
do_reflect	if true, the intermediate results are reflected
crc	CRC-32 value to update.

Returns

computed CRC-32.
