Abstract
A system for generating CRC code words associated with data ranging up to w-bytes in width to be communicated over a communications channel includes a first plurality of serially coupled code-generation blocks each for generating a CRC value based on data input to each block, respective blocks of the first plurality configured for receiving data inputs having respective byte widths ranging from 2+M to 2+M, where N is equal to log(w), and M is an offset value, and L is a whole number based on a maximum propagation delay criteria; a second plurality of parallel coupled code-generation blocks each for generating a CRC value based on data inputs, respective blocks of the second plurality configured for receiving data having respective byte widths ranging from 2−1+M to 2; and, a device for selecting particular CRC code generation blocks in the first and second pluralities to be included in a CRC calculation based on the data input; wherein any number of data input bytes may be processed.
