BCH encoder and decoder
Maturity plannedTargets FPGA + ASICDifficulty HardPriority 2
Binary BCH encoder with parallel syndrome computation, Berlekamp-Massey error locator and Chien search; configurable field size and correction capability t as used in NAND flash ECC.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
