The BCH decoder has four main functional blocks along with memory blocks. Syndrome calculation block calculates syndrome components which tell about presence of errors in the encoded data. Brelekamp Massey's algorithm block computes error locator polynomial whose inverse of roots gives error locations. A polynomial solver in find error location unit solves this error locations polynomial and gives error locations indicated. For binary decoding the correction value will be just the flip of the error value which can be done using XOR gate only.
