    摘要: A method for processing encoded data using error control coding in accordance with the present invention includes: a) obtaining Q codewords and P codewords from a storage location, wherein the Q codewords and the P codewords are all obtained in a single pass through the storage location, b) calculating P partial syndromes for said P codewords, c) calculating Q partial syndromes for the Q codewords, and d) storing the Q partial syndromes and the P partial syndromes in a buffer that is separate from the main memory. In some embodiments, storing the Q partial syndromes and the P partial syndromes in the buffer includes storing the Q partial syndromes in a first buffer, and storing the P partial syndromes in a second buffer.
