Abstract
A parallel cyclic redundancy checking circuit which determines the validity of digital, binary, cyclical data. The parallel structure of this circuit enables it to check high frequency data. Shift registers are used to store sequentially occurring parallel groups of data and a feedback network comprising exclusive-or gates provide a coding arrangement which produces a resultant data pattern to indicate the validity of the cyclical parallel input data.
