Reed Solomon encoding and decoding IP core 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), symbols are coded on 4 bits and the maximum size of a message after encoding is 15 symbols (60 bits).

Key features

  • Configurable input data size

    Configurable ECC size

    1 or 2 symbol correction capacity, symbol size is a quarter of the ECC size

    Decoder indicates when a symbol is corrected

  • Decoder indicates when an incorrigible error is detected

    Encoder is a combinatory entity

    Configurable output delay for decoder
