The CRC- 16 bits code computes a 16-bit cyclical redundancy check (CRC) algorithm on an input serial data stream. The polynomial can be defined to implement CRC functions, such as the CRC-16 or CCITT algorithm. A seed value can be specified to initialize the starting data value. What is CRC CCITT …

A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data. Blocks of data entering these systems get a short check value attached, based on the remainder of a polynomial division of their contents. On … See more CRCs are based on the theory of cyclic error-correcting codes. The use of systematic cyclic codes, which encode messages by adding a fixed-length check value, for the purpose of error detection in communication … See more CRCs are specifically designed to protect against common types of errors on communication channels, where they can provide quick and … See more Mathematical analysis of this division-like process reveals how to select a divisor that guarantees good error-detection properties. In this analysis, the digits of the bit strings are taken as the coefficients of a polynomial in some variable x—coefficients that … See more A CRC-enabled device calculates a short, fixed-length binary sequence, known as the check value or CRC, for each block of data to be sent or stored and appends it to the data, forming a codeword.
