ECC algorithm and the realization of the VHDL for high-capacity solid-state storage

In order to ensure the reliability of data, ECC is increasingly used in large-capacity data Nand type Flash storage. This paper describes the ECC algorithm, and designs a special error correction method for a radar recorder. The VHDL language description of the ECC algorithm is achieved and successfully embedded into the original program recorder, needs the actual data only on clock, not requires to calculate the additional timing, and occupies less system resources when running. It can correct one bit error and detect two bit errors, become an important way in data protection, and have the significant practical application value.
