METHOD AND SYSTEM FOR PARALLEL CRC CALCULATION

A system and method for a parallel CRC calculation is provided. A set of parallel inputs are loaded into a control register, and this control register is then used with a parallel table look-up operation to look up CRC entries for each of the inputs using a single instruction. This is repeated until each input has been processed completely to produce a complete CRC. The parallel table look-up operation may be executed using the PowerPC Altivec vperm instruction.
