Error correction method for reed-solomon product code

摘要

A method and apparatus for error correction of an encoded data stream. A demodulated data stream is saved in an input buffer. A first correction process is performed on-the-fly in the input buffer. The data is transferred to an external SDRAM after correction. A data frame is copied from the external SDRAM to an embedded SRAM. A multipass correction is started in the embedded SRAM. The corrected data frame is copied back from the embedded SRAM to the external SDRAM.
