1. A data processing method, comprising the steps of:
- (a) initializing a syndrome vector to be an (n−
1)th symbol;
(b) finding a corresponding mask based on the syndrome vector, wherein a value of the mask is equal to 0 when a value of the (n−
1)th symbol is equal to 0;
(c) correcting a known constant based on the mask, wherein a value of the known constant corrected based on the mask is equal to 0 when a value of the syndrome vector is equal to 0;
(d) inputting the syndrome vector to a log look-up table to correspondingly find log data;
(e) performing, based on the log data and a log known constant, a modulo addition operation corresponding to log maximum data to find a log sum; and
(f) inputting the log sum to an anti-log look-up table to correspondingly find operational data.

Abstract
A data processing method includes the steps of: initializing a syndrome vector to be an (n−1)th symbol; finding a corresponding mask based on the syndrome vector, wherein the mask is zero when the (n−1)th symbol is zero; correcting a known constant, which is zero when the syndrome vector is zero, based on the mask; inputting the syndrome vector to a log look-up table to correspondingly find log data; performing a modulo addition operation corresponding to log maximum data to find a log sum based on the log data and a log known constant; and inputting the log sum to an anti-log look-up table to correspondingly find operational data.

10. A computer system medium having a computer-executable instruction for performing a data processing method, the data processing method comprising the steps of:
-
(a) initializing a syndrome vector to be an (n−
1)th symbol;(b) finding a corresponding mask according to the syndrome vector, wherein a value of the mask is equal to 0 when a value of the (n−
1)th symbol is equal to 0;(c) correcting a known constant based on the mask, wherein a value of the known constant corrected based on the mask is equal to 0 when a value of the syndrome vector is equal to 0; (d) inputting the syndrome vector to a log look-up table to correspondingly find log data; (e) performing, based on the log data and a log known constant, a modulo addition operation corresponding to log maximum data to find a log sum; and (f) inputting the log sum to an anti-log look-up table to correspondingly find operational data. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
