Product Description

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.

Key Features and Benefits

Flexible RS Decoder meeting the requirements of most standards that employ RS codes including: IEEE 802.16, DVB-x, G.709, ETSI-BRAN, and CCSDS
Fully synchronous design using a single clock
Supports continuous input data with no gap between code blocks
Supports symbol size from 3 to 12 bits and any primitive field polynomial for a given symbol width
Supports code block length variable up to 4095 symbols
Code block length and number of check symbols can be varied dynamically on a block by block basis
Supports shortened codes, error and erasure decoding and parameterizable number of errors corrected
Counts number of errors corrected and flags failures
Support for multi-channel implementation which improves core efficiency for high speed applications such as OC-192
Updated puncturing option which improves core efficiency for standards such as IEEE802.16d
New self-recovery mode feature
Variable check symbol option added
Extra bit error statistics outputs
Extra status outputs: marker bits allow input data to be tagged

DS862 - LogiCORE IP Reed-Solomon Decoder v8.0 Data Sheet (AXI) (DS862) (v8.0)

The LogiCORE™ Reed-Solomon decoder (with the Reed-Solomon algorithm) is used for Forward Error Correction (FEC) in systems where data are transmitted and subject to errors before reception, for example, communications systems, disk drives, and so on. The core meets the requirements of most standards that employ RS codes, such as CCSDS, DVB, ETSI-BRAN, IEEE802.16, G.709, IESS-308. This document contains information about the AXI4 version of the core.
