HIGH PERFORMANCE CRC CALCULATION METHOD AND SYSTEM WITH A MATRIX TRANSFORMATION STRATEGY

A CRC calculation method and system for generating a CRC from a message is provided while improving the process time and simple to implement. A linear mapping matrix is used for the operation of the LFSR to generate the CRC and the maximum value of the non-zero entries in the mapping matrix is reduced by applying one or more raw operations to the linear mapping matrix in advance before the computation of mapping the input message to the CRC result. Flip-flops are additionally inserted before the generator matrix to obtain a pipeline architecture so as to further improving the operation speed thereof.
