Methods and systems for parallel column twist interleaving

A system configured for applying parallel bit-interleaving, the system comprising:

• a memory that stores data during the parallel bit-interleaving;
• an input circuit that reads from an input bitstream, in each particular cycle of a plurality of cycles of the parallel bit-interleaving, a number of bits;
• one or more processing circuits that process the read bits, wherein the processing comprises:
• applying a first adjustment to a first combination of bits that comprises the read bits and additional bits, wherein each of the additional bits comprises a previously read bit in the input bitstream or a pre-set bit;
• when one or more conditional criteria are met, applying a second adjustment to a second combination of bits that comprises bits corresponding to previously read bits, wherein the one or more conditional criteria comprise completing processing of a full column;
• writing into the memory a number of bits corresponding to the first combination of bits and/or the second combination of bits;
• and
• reading from the memory a number of bits, for generating a cycle output corresponding to the particular cycle.
