Lines Matching defs:bit
37 * Calculates the 22-bit hamming code for a 256-bytes block of data.
65 * index bit to 0 (even) or 1 (odd).
77 * - P4 -> bit 2 of index is 0 --------------------'
78 * - P4' -> bit 2 of index is 1.
79 * - P2 -> bit 1 of index if 0.
81 * We deduce that a bit position has an impact on all
82 * even Px if the log2(x)nth bit of its index is 0
85 * and on all odd Px' if the log2(x)nth bit
