Byte-wise crc calculations

WebIt is also possible to calculate CRC32 in a bytewise manner, eliminating the bit loop altogether. This approach is about six times faster than the previous one but needs additional memory for a pre-calculated 256-word lookup table. The idea is described in Todd K. Moon, Error Correction Coding.

WebThe results of the CRC are calculated one bit at a time and the resulting equations for each bit are examined. The CRC register prior to any shifts is shown in Table 1. The CRC register after a single bit shift is shown in Table 2. The CRC register after two shifts is shown in Table 3. This process continues until eight shifts have occurred.
