"The Reed-Solomon Encoder LogiCORE module is a high speed, compact design that implements many different Reed-Solomon coding standards including G.709, DVB, ATSC, IEES, ITU-T J.83 and CCSDS. The core is fully synchronous, using a single clock, and supports continuous output data with no gap between code blocks. The core is parameterizable, allowing designers to control the symbol width and the code block length. This module supports shortened codes and any primitive field polynomial for a given symbol width. The core supports a user-configured generator polynomial.
