SYSTEMS AND METHODS FOR EFFICIENT LOW DENSITY PARITY CHECK (LDPC) DECODING

A method for low density parity code decoding according to one embodiment includes sequentially processing groups of variable node (vim& values associated with a codeword using a plurality of vnode logic modules and outputting updated vnode values; storing the vnode values and updated vnode values in a vnode memory; sequentially processing groups of cnode values using a plurality of check node (cnode) logic modules and outputting updated vnode values; storing the (mode values and updated (mode values in a mode memory; and checking the codeword using the updated vnode values and the updated mode values.
