Abstract

A linear feedback shift register (LFSR) based design is applied to cyclic redundancy check (CRC) modules, in which a CRC building block having a minimum width is implemented. The CRC building block accepts a generator polynomial as an input design parameter to build a CRC block module. The modularity of the design then allows a larger CRC block design to be constructed from multiple CRC block modules such that wider data width blocks may be accommodated. The LFSR based designs are extended to communication systems that may require scrambling and descrambling functionality.
