General Description
The RS Compiler offers a fully parameterizable RS encoder and RS decoder. 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
- 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
