Therefore, we convert the division of GF(2) polynomial into binary form, which is no different from ordinary division, except that addition and subtraction operations have no carry and exit.įor example, if 11010 / 1001 is calculated based on the above rules, then the quotient is 11 and the remainder is 101. For example, g(x)=x^4 + x + 1, then the binary form of g(x) is 10011. The coefficient of each generating polynomial can only be 0 or 1, so we can convert it into binary form. If you look at this rule, it is actually an exclusive or operation. To put it bluntly, it is the following operation rules: 0 + 0 = 0 0 - 0 = 0 There is only one variable x in GF(2) polynomial, and its coefficients are only 0 and 1, for example: 1 *x^6 + 0*x^5 + 1*x^4 + 0*x^3 + 0*x^2 +1*x^1 + 1*x^0Īddition and subtraction operations do not consider carry and carry. It is based on the arithmetic of GF(2) polynomial. The mathematical basis of CRC algorithm is no longer wordy. * This table was generated by the following program.Ĭ = c & 0x80000000 ?

The most commonly used polynomial lengths are:Ĭopyright (C) 2009-2020 Free Software Foundation, Inc. The most important property of a polynomial is its length (the maximum degree (exponent) of any term in the polynomial) + 1, because it directly affects the length of the calculated check value. At the same time, the collision probability must be minimized to maximize the overall detection ability. The choice of generating polynomial is the most important part of CRC algorithm. The length of the check value is fixed to 8 characters, so the function that generates the value is sometimes used as a hash function. Therefore, in the data storage and Data communication CRC is everywhere in the field: the famous communication protocol X.25 uses CRC-CCITT for FCS (frame error detection sequence), and CRC 32 is used for ARJ, LHA and other compression tools, disc drive CRC16 is used for reading and writing, and CRC is also used as error detection means for general image storage formats GIF and TIFF. In terms of performance and overhead, it is far better than that Parity check And arithmetic and check. Judging from its error detection ability, the probability that it can not find the error is only less than 0.0047%. It has strong error detection ability, low cost and easy to use encoder And detection circuit.

The full name of CRC is Cyclic redundancy check. Among many error detection methods, CRC is the most famous one. The CRC (Cyclic Redundancy Check) check utility library is available in data storage and Data communication In order to ensure the accuracy of the data, we have to use the means of error detection. The CRC-32 algorithm itself converts a variable length string into a string of 8 characters. If the two are equal, there is no data corruption. When the data is received, the checksums are generated again and compared to the transmitted checksums. When sending data, short checksums are generated based on the data content and sent with the data.
