Optimized for

Reed-Solomon codes are calculated in a finite field of elements, or Galois fields GF(2

by a primitive polynomial P(x). The degree of the primitive polynomial m defines the number of bits per data symbol

(m = bits per symbol) and the maximum length of the Codeword (2

generator polynomial G(x) further defines the field of Codewords that the parity symbols are derived from.

MC-ACT-RSENC is a "core" logic module specifically designed for Actel FPGAs. The logic symbol of this core is

shown in Figure 1.
