Abstract
A method for shortening latency of Chien's search and related circuit are disclosed. The method includes the steps of: determining a shifted factor, p; receiving a BCH codeword; computing a syndrome from the BCH codeword; finding an error-location polynomial based on the syndrome; and processing Chien's search for the error-location polynomial to find out roots thereof. p is a number of successive zeroes from the first bit of the BCH codeword, the Chien's search starts iterative calculations by substituting a variable of the error-location polynomial with a nonzero element in Galois Field, GF(2), and the nonzero element ranges from αto α, wherein n is a codelength of the BCH codeword and equals 2−1, and m is a positive integer.
