Cyclic Redundancy Check (CRC)

Wesley Peterson

CRC is a highly reliable error detection method that checks for errors in digital data transmission. It is widely used in network protocols, storage devices, and other communication systems.
Cyclic Redundancy Check (CRC) is a widely used error detection method that is commonly employed in network communication systems. It is a checksum algorithm that calculates a unique value, known as a CRC-32 or CRC-16, from data packets to detect errors during transmission. The CRC value is generated by dividing the original data by a predetermined polynomial and appending the remainder as the checksum. If the received CRC value does not match the calculated CRC value at the receiver's end, it indicates the presence of errors in the data.

Polynomial: CRC-32: 0x04C11DB7, CRC-16: 0x8005

Checksum size: 32 bits for CRC-32, 16 bits for CRC-16

Error detection capability: Can detect all single-bit errors, non-multiple-bit errors, and errors involving an odd number of bits

Efficiency: Provides good error detection with a low probability of undetected errors

Broad applicability: Suitable for various data transmission protocols, including Ethernet, USB, and SATA

More information on most reliable type of error detection method

Background Information: When it comes to detecting errors in data transmission, there are several methods available. The most commonly used methods are parity checking, cyclic redundancy checking (CRC), and checksum. Each of these methods has its own advantages and disadvantages, and the choice of which method to use depends on the requirements of the specific system. Parity checking is the simplest and most basic error detection method. It involves adding an extra bit to each byte of data, which is used to detect errors in transmission. The parity bit is set to 1 or 0 depending on the number of 1s in the byte, so that the total number of 1s in the byte, including the parity bit, is always even or odd. If an error occurs during transmission, the parity check will fail and the receiver can request a retransmission of the data. Cyclic redundancy checking (CRC) is a more complex error detection method that is commonly used in data networks. It involves adding a CRC code to the end of the data stream, which is calculated based on the contents of the data. The receiver then recalculates the CRC code and compares it to the one received. If the codes match, the data is assumed to be error-free. If not, the receiver requests a retransmission of the data. Checksum is another error detection method that involves adding an extra field to the data stream, which contains a value calculated based on the contents of the data. The receiver calculates the checksum of the received data and compares it to the one sent by the sender.
