Reed Solomon IP Core

Overview

The Reed Solomon encoding and decoding IP cores designed to provide protection for data storage in space applications.
Reed Solomon is a block code, the transmitted codeword is divided in block of data called symbols. Symbols are coded on several bits as elements of a Galois field. The Reed Solomon IP is based on the Galois field GL(2^4), where symbols are coded on 4 bits and the maximum size of a message after encoding is 15 symbols (60 bits).
The Reed Solomon IP core offers the possibility to address data bus with more than 60 bits by implementing several encoder or decoder inside the same IP.

Key Features

Configurable input data size
Configurable ECC size
1 or 2 symbol correction capacity, symbol size is half the size of ECC
Decoder indicates when a symbol is corrected
Decoder indicates when an incorrigible error is detected
