Abstract
A low power Chien searching method employing Chien search circuitry comprising at least two hardware components that compute at least two corresponding bits comprising a Chien search output, the method comprising activating only a subset of the hardware components thereby to compute only a subset of the bits of the Chien search output; and activating hardware components other than those in the subset of hardware components, to compute additional bits of the Chien search output other than the bits in the subset of bits, only if a criterion on the subset of the bits of the Chien search output is satisfied.
