Abstract
본 발명은 4소실 정정에 있어서 4소실 정정의 판별식을 향상시킨 에러 정정 범위를 판별하는 방법에 관한 것이다.The present invention relates to a method for determining an error correction range that improves a discrimination equation for four-sided correction in four-sided correction.
에러 정정 범위를 판별하는 방법은 에러값을 구하는 에러값 추출단계, 제1신드롬에 의한 제1판별식에 상기의 에러값을 대입하여 상기의 제1판별식이 0인지를 판단하는 제1판별단계, 제2신드롬에 의한 제2판별식에 상기의 에러값을 대입하여 상기의 제2판별식이 0인지를 판단하는 제2판별단계, 제3신드롬에 의한 제3판별식에 상기의 에러값을 대입하여 상기의 제3판별식이 0인지를 판단하는 제3판별단계, 제4신드롬에 의한 제4판별식에 상기의 에러값을 대입하여 상기의 제4판별식이 0인지를 판단하는 제4판별단계 및 상기의 제1, 제2, 제3, 제4판별단계에서 모두 0인지를 검출하는 검출단계로 이루어지며, 상기의 제1판별식은 A0=S0+E1+E2+E3+E4이고, 상기의 제2판별식은 A1=S1+E1×1+E2×2+E3×3+E4×4이고, 상기의 제3판별식은 A2=S2+E1×1²+E2×2²+E3×3²+E4×4²이고, 상기의 제4판별식은 A3=S3+E1×1³E2×2³+E3×3³+E4×4³이다.A method for discriminating an error correction range includes an error value extracting step of obtaining an error value, a first discriminating step of discriminating whether the first discriminating equation is 0 by substituting the error value into a first discriminating equation by a first syndrome, A second discrimination step of discriminating whether the second discrimination equation is 0 by substituting the above error value into the second discrimination equation by the second syndrome, or by substituting the above error value into the third discrimination equation by the third syndrome A fourth discrimination step of discriminating whether the fourth discrimination equation is 0 or not by substituting the error value into a fourth discrimination equation by the fourth syndrome, E0 + E1 + E2 + E3 + E4 where A0 = S0 + E1 + E2 + E3 + E4, and the second discrimination formula is A0 = The discriminant is A1 = S1 + E1 x 1 + E2 x 2 + E3 x 3 + E4 × 4, and the third discriminant is A2 = S2 + E1 x 1² + E2 × 2 + E3 3 + E4 4 < 2 >, and the fourth discriminant is A3 = S3 + E1 x 1 < 2³ + E3 × 3³ + E4 × 4 ³.
