Abstract
Provided are a Cyclic Redundancy Check (CRC) circuit, and a method and an apparatus thereof, a chip and an electronic device, which belong to the technical field of computers. Herein, the cyclic redundancy check circuit may include: a configuration module configured to acquire configuration information and an information field, a CRC arbitration module configured to determine a generator polynomial according to the configuration information, a CRC control module configured to respond to triggering of the CRC arbitration module and output a clock signal, a coefficient corresponding to each power in the generator polynomial and the information field, a parallel iteration module configured to respond to the clock signal and implement parallel iteration for the information field according to the coefficient corresponding to the each power in the generator polynomial, as to output an iteration result, and a CRC output module configured to package the information field according to the iteration result.
