    performing a first correction process on-the-fly in the input buffer;

    transferring the data to an external DRAM after correction;

    copying the data from the external DRAM to an embedded SRAM;

    starting a multipass correction in the embedded SRAM;

    copying the corrected data back from the embedded SRAM to the external DRAM after the multipass correction; and

    deinterleaving and/or correcting streaming discontinuities in the external DRAM.
