BCH编译码器在NAND Flash控制器中的应用研究
Application and Research of BCH Encoder/Decoder in NAND Flash Controller
摘要
Abstract
Based on the requirements of operating rate and correction capability for ECC of solid state memory for space application,a new architecture of parallel BCH encoder and decoder applied in NAND Flash Controller is presented. Design a new architecture of BCH decoder,and improve syndrome calculation algorithm. It utilizes encoder to calculate out syndrome polynomial first,and then uses decoder to calculate out the syndrome. Compared with other decoder which directly calculates out the syndrome,although it has a little decoding time increasing,could significantly reduce the usage of resources. This design combined with some other measures to save resources and improve speed,could better meet the demands of space application.关键词
