摘要
针对NANDFlash因制造工艺不断提高而导致其内部数据区随机错误不断增加的现象,传统的8bit,16bit BCH编译码器已难以满足广大客户的需求,现提出了一种新型BCH编译码器结构,所设计的(8640,8192)编码译码器可以在单页数据(1024B)的基础上纠错32bit数据,并在译码电路中,在编码输入电路,伴随式模块与chien搜索模块采取并行算法处理,大大提高了数据的处理速度。
According to NANDFlash due to manufacturing process continuously improve its internal data area due to random errors increasing phenomenon, the traditional 8 bit, 16 bit BCH codec has been difficult to meet the needs of our customers, this paper proposes a novel BCH encoding and decoding structure, the design of （86408192） encoder and decoder can be in a single page of data （ 1024 B） error correction based on 32 bit data, and the decoding circuit, input circuit in the code, along with the module and Chien module to search parallel algorithms for the processing, greatly improving the speed of data processing.
