    摘要： An error correcting method for correcting an error of digital data is provided. The method includes a plurality of sub-frames including a plurality of block code words, including: extracting and aligning a block code word, which is included in a past sub-frame; and generating a redundant data block code word by use of a block code word, which is included in a latest sub-frame, and the aligned block code word, and adding the redundant data block code word to the latest sub-frame, wherein the redundant data block code word is used for generating a redundant data block code word, which is added to a next sub-frame.

    摘要： A system for detecting an address or data error in a memory system. During operation, the system stores a data block to an address by: calculating a hash of the address; using the calculated hash and data bits from the data block to compute ECC check bits; and storing the data block containing the data bits and the ECC check bits at the address. During a subsequent retrieval operation, the memory system uses the address to retrieve the data block containing the data bits and ECC check bits. Next, the system calculates a hash of the address and uses the calculated hash and the data bits to compute ECC check bits. Finally, the system compares the computed ECC check bits with the retrieved ECC check bits to determine whether an error exists in the address or data bits, or if a data corruption indicator is set.

    摘要： In recent years, researchers have found that some XOR erasure codes lead to higher performance and better throughput in fault-tolerant distributed data storage applications. However, little consideration has been given to the advantages of parallel processing or hardware implementations taking advantage of the emergence of multi-core processors. An efficient horizontal MDS-like (Maximum Distance Separable) RAID-6 scheme, called EEO, is provided which significantly improves the performance of the decoding procedure in parallel implementations with little storage overhead. EEO is the fastest and most efficient double disk failure recovering algorithm in RAID-6, at the cost of only two more parity symbols. In practice, it is very useful for application where high decoding throughput is desired.
