Reed-Solomon Encoder and Decoder are commonly used in data transmission and storage applications, such as broadcast equipment, wireless LANs, cable modems, xDSL, satellite communications, microwave networks, and digital TV. The Reed-Solomon Decoder LogiCORE module is a high speed, compact design that implements many different Reed-Solomon coding standards including G.709, DVB, ATSC, IEES and CCSDS. The core is fully synchronous, using a single clock, and supports continuous input data with no gap between code blocks. The core is parameterizable, allowing designers to control the symbol size, the code block length, the number of errors corrected, and the control signal behavior. This Decoder supports both error and erasure decoding. It supports any primitive field polynomial for a given symbol size. The core also counts the number of errors corrected and flags any failures.
