1. An apparatus for performing encoding operations, the apparatus comprising:

  • a first set of memory locations to store information bits;

    a second set of memory locations to store parity bits;

    a permutation module to read a bit from the first set of memory locations and combine the read bit to a bit in the second set of memory locations based on a corresponding index of the first set of memory locations and a corresponding index of the second set of memory locations; and

    an accumulator to perform accumulation operations on the bits stored in the second set of memory locations,wherein two or more memory locations of the first set of memory locations are read by the permutation module different times from one another.
