Abstract
An encoder encodes input data utilizing a binary symmetry-invariant product code. The encoder includes circuitry including a half-size data array including D rows each having storage for H data bits (D=2×H+1). The encoder is configured to access bits of each row of the product code by reading a first H-bit data word from one of the D rows and a second H-bit data word across H different rows of the half-size data array. The encoder additionally includes a register configured to receive the bits of each row of the product code and to rotate the bits to obtain the rows of the product code and a row parity generator configured to generate row parity for each row of the product code. The encoder finally includes a column parity generator configured to generate, based on the row parity, column parities for the parity bits of all rows of the product code.
