WebApr 13, 2024 · The number of ECC bits for generation is dependent on size of the data & can be calculated using below formula : SECDED: 2^n+1: where n+1 = number of ECC bits. DECTED: 2^n+2: Where n+2 = number of ECC bits. For E.g : For 8 Bits of Data with single bit correction and double bit detection (SECDED) we would need 3 ECC bits i.e from 2^(2+1). probation act trinidadWeb“1"s in the pattern plus parity bit. Parity bits are sufficient to catch all single errors in the pattern plus parity bit as this will change a single 1 to a 0 or vice versa and therefore upset the parity calculation.
