Abstract
Cyclic redundancy calculations are provided by operating on a data stream, e.g., a data stream in an implantable medical device, to perform a polynomial division thereon using one of a first cyclic redundancy code generator polynomial and a second cyclic redundancy code generator polynomial. The first cyclic redundancy code generator polynomial is a higher order polynomial than the second cyclic redundancy code generator polynomial and contains all terms of the second cyclic redundancy code generator polynomial. The polynomial division may be implemented using linear feedback shift register circuitry and circuitry to select between the use of the first or second cyclic redundancy code generator polynomial.
