Abstract
Data is protected during conversion from one or more source error correction codes to one or more destination error correction codes by generating check bits of the destination error correction codes prior to a detection for errors in the source error correction codes. After commencing generation of these check bits, a detection is made for any errors in the source error correction codes. These errors are subsequently corrected in the destination error correction codes by complementing the erroneous bits of the destination error correction code. In addition, various logic reduction techniques may also be implemented to increase efficiency.
