Data Integrity Techniques: Aviation Best Practices for CRC

WebAug 18, 2024 · Error Coding. A generic term for a set of bits which is used to detect errors in a message. A single bit error code is a parity bit, as commonly seen in RS-232 and other simple protocols. The next level up is a checksum, which can be achieved by XOR-ing values together or summing them in various ways. WebMay 28, 2013 · 1. A CRC is not processor-intensive. All it adds to your exclusive-or is a table lookup. The operation on each byte is simply: crc = crc8_table [crc ^ *data++]. See below. The downside of doing just an exclusive-or is that there are many simple errors that cancel each other, resulting in a false-positive check. A CRC is much better. harp inn bridgnorth
