Abstract:
A Reed-Solomon encoder/decoder apparatus comprising:a decoder setup block having a first writable register storing decode a Galois field order and a second writable register storing an indication of a decode primitive polynomial; a decoder block receiving Reed-Solomon coded input data and connected to said decoder setup block, said decoder block decoding said Reed-Solomon coded input data according to said decode Galois field order stored in said first writable register and said indication of a decode primitive polynomial stored in said second writable register, and outputting decoded data; an encoder setup block having a third writable register storing an encode Galois field order and a fourth writable register storing an indication of an encode primitive polynomial; and an encoder block receiving input data and connected to said encoder setup block, said encoder block Reed-Solomon encoding said input data according to said encode Galois field order stored in said third writable register and said indication of an encode primitive polynomial stored in said fourth writable register, and outputting encoded data.
