  • High speed DVD error correction engine
    Patent number: 6718506
    Abstract: Speed of operation is increased in a DVD error correcting apparatus by first correcting rows of DVD data from PI check bytes in a PI engine and storing it in SRAM and feeding the corrected PI data into SDRAM and a PO engine, where only the syndromes are stored in an 8K SRAM, and only the bytes to be corrected are written to SDRAM. Speed of operation is enhanced by transferring most of the random and small burst of data to SRAM in big bursts with a minimum number of random accesses to the main SDRAM or DRAM.
