Abstract: Methods for correcting errors in a GFP-T superblock include buffering the 64 bytes of data in an 8×8 byte buffer, buffering the flag byte in a separate buffer, calculating the CRC remainder, and performing single and double bit error correction in three stages. In the first stage, the CRC remainder is compared to a single bit error syndrome table and if an error is located, it is corrected. In the second stage, the CRC remainder is compared to a double bit error syndrome table and if an error is located, it is corrected. The third stage corrects the second error of a double bit error. The flag byte is processed first, followed by the data bytes, eight bytes at a time.
