1. About This Compiler
This document describes the Altera ? Reed-Solomon (RS) Compiler. The Altera RS
Compiler comprises a fully parameterizable encoder and decoder for forward error
correction applications. RS codes are widely used for error detection and correction in
a wide range of DSP applications for storage, retrieval, and transmission of data. The
RS Compiler has the following options:
■
■
■
■
Erasures-supporting option—the RS decoder can correct symbol errors up to the
number of check symbols, if you give the location of the errors to the decoder.
Refer to “Erasures” on page 3–2 .
Variable encoding or decoding—you can vary the total number of symbols per
codeword and the number of check symbols, in real time, from their minimum
allowable values up to their selected values, when you are encoding or decoding.
Error symbol output—the RS decoder finds the error values and location and adds
these values in the Galois field to the input value.
Bit error output—either split count or full count
