Abstract
Apparatuses and methods associated with instant syndrome computation in a layered LDPC decoder are described. In one embodiment an apparatus includes a first hardware layer configured to compute a first group of syndrome values from one or more bit values in the codeword and a second hardware layer configured to compute a second group of syndrome values from one or more bit values in the codeword. The apparatus also includes a first physical memory associated with the first hardware layer and configured to store the first group of syndrome values until the syndrome values change due to a change in a codeword bit value. The apparatus also includes a second physical memory associated with the second hardware layer and configured to store the second group of syndrome values until the syndrome values change due to a change in a codeword bit value.
