COMPUTATION OF CYCLIC REDUNDANCY CHECKS VIA TABLE LOOK-UP
A Cyclic Redudancy Check (CRC) code provides a simple, yet powerful method for the detection of errors during digital data transmission.
JetForm for E-Mail/C's calculation capabilities and its data validation rules, including range and numeric checks, table look-ups
and mandatory fields.
This algorithm requires only five table look-ups
, five XOR's, and four shifts per input byte.
