WebMar 15, 2024 · To compute the CRC-16/CCITT-FALSE on your data, you exclusive-or the first 16 bits of your data with the Init value of 0xffff. That gives fe ef C0 03 00 01. Now do what you know on that, but with the polynomial 0x11021. You will get what is in the table, 0xb53f. Now you know how to apply Init. Computation 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 hardware by a modified shift register, and in software by a series of equivalent algorithms, starting with simple code close to t…
