Systems and methods for efficient low density parity check (LDPC) decoding

摘要

A system for low density parity code decoding according to one embodiment includes a plurality of variable node (vnode) logic modules for sequentially processing groups of vnode values associated with a codeword and outputting updated vnode values; a vnode memory for storing the vnode values and updated vnode values; a plurality of check node (cnode) logic modules for sequentially processing groups of cnode values and outputting updated vnode values; a cnode memory for storing the cnode values and updated cnode values; and logic for checking the codeword using the updated vnode values and the updated cnode values. Additional systems and methods are also presented.
