WebThe most important attribute of the polynomial is its length (largest degree (exponent) +1 of any one term in the polynomial), because of its direct influence on the length of the computed check value. The most commonly used polynomial lengths are: 9 bits (CRC-8) 17 bits (CRC-16) 33 bits (CRC-32) 65 bits (CRC-64) Resources Web以太网CRC32计算--软件与算法的结果对比[英] Ethernet CRC32 calculation - software vs algorithmic result. 2024-10-07.
