    • Exemplary embodiments for providing multi-bit error correction based on a BCH code are provided. In one such embodiment, the following operations are repeatedly performed, including shifting each bit of the BCH code rightward by 1 bit while filling the bit vacated due to the rightward shifting in the BCH code with 0, calculating syndrome values corresponding to the shifting of the BCH code, and determining a first error number in the BCH code under the shifting based on the syndrome values corresponding to the shifting of the BCH code. In the case where the first error number is not equal to 0, modified syndrome values are calculated corresponding to the shifting of the BCH code. The modified syndrome values are those corresponding to the case that the current rightmost bit of the BCH code under the shifting is changed to the inverse value. Additional operations are performed as described herein.
    • 提供了用于基于BCH码提供多位纠错的示例性实施例。 在一个这样的实施例中,重复执行以下操作,包括将BCH码的每一位向右移位1位,同时填充由于BCH码中的向右移位而退出的位0,计算对应于 BCH码,并且基于与所述BCH码的移位相对应的校正子值,在所述移位下确定所述BCH码中的第一错误号。 在第一错误号不等于0的情况下,对应于BCH码的移位来计算修正的综合征值。 修正后的综合征值是对应于移位处的BCH码的当前最右边位置变为反向值的情况。 如本文所述执行附加操作。
