    • Provided are systems and methods for rate matching and de-rate matching on digital signal processors. For example, there is a system for rate matching and de-rate matching, where the system includes a memory configured to contain a plurality of blocks of data, and a digital signal processor configured to pre-compute permutation parameters common to the plurality of blocks, wherein the plurality of blocks are subject to a set of given puncturing parameters. The digital signal processor is configured to process each block in the plurality of blocks by computing a block signature from pre-computed puncturing thresholds, matching the block signature to one of a set of pre-computed zone signatures, deriving a zone index corresponding to the one matched pre-computed zone signature, and applying pre-computed permutation and puncturing transformations corresponding to the zone index to the block.
