This section discusses functions implementing the Reed-Solomon (RS) codes. The section adopts a traditional notation RS(n,k) for n-symbol encoded block of k-symbol user's data. The IPP implementation of the RS functionality is limited to considering only m-bit symbols (m<=8). Thus the implementation refers to Arithmetic Functions for Polynomials over GF(2 m) and GF(2m) Arithmetic Functions, described earlier in this chapter.
Intel IPP implements only systematic RS codes, which means that the user's data to be encoded appears verbatim in the encoded codeword.
