APPARATUS FOR GENERATING CYCLIC REDUNDANCY CHECK CODE

摘要

PURPOSE: An apparatus for generating a cyclic redundancy check code is provided to reduce processing time for generating a cyclic redundancy check code by increasing the number of a data bit which is processed at one clock cycle through parallel processing. CONSTITUTION: A CRC code generator(100) includes a serial/parallel convertor(110), adders(121-128,171-178,181-188), and selectors(131-138). The CRC code generator includes the parallel-serial converter(140), masking arithmetic units(151-156), and shift register lines(161-163). The serial/parallel convertor parallely transforms inputted data into eight data. Each of adders performs an OR operation feedback data outputted in a final shift register line and data outputted in the serial/parallel convertor. Shift register lines respectively include eight shift registers which are formed in parallel.
