WebComputation of a cyclic redundancy check is derived from the mathematics of polynomial division, modulo two.In practice, it resembles long division of the binary message string, with a fixed number of zeroes appended, by the "generator polynomial" string except that exclusive or operations replace subtractions. Division of this type is efficiently realised in … WebIn ISA-L CRC, function crc32_ieee is * actually designed for normal CRC32 IEEE version. And function * crc32_gzip_refl is actually designed for reflected CRC32 IEEE. * These two versions of CRC32 IEEE are not compatible with each other. * Users who want to replace their not optimized crc32 ieee with ISA-L's * crc32 function should be careful of ...
