  • Symbol based algorithm for hardware implementation of cyclic redundancy check
    Patent number: 6295626
    Abstract: A method and apparatus for generation of CRC generation/checker circuitry. A symbolic simulation-based algorithm to derive boolean equations for a parameterizable data-width CRC generator/checker is described. The equations generated are used to implement a data-flow representation of the CRC circuit in VHDL. The VHDL description is then synthesized into gates.
