NAND Flash, as a low-cost and high-density embedded storage, has been widely used in various embedded systems. However, due to its unique characteristics, NAND Flash requires special file systems to manage storage. Therefore, this paper proposes a design and implementation of a block-based embedded NAND Flash file system.Firstly, this paper analyzes the characteristics of NAND Flash memory, including its read and write speed, erase operation, bad block handling and life cycle issues. Then, based on these characteristics, this paper proposes a block-based file system design.精品文档---下载后可任意编辑Secondly, this paper mainly introduces the implementation of the file system designed in this paper.
