说明：  嵌入式系统中闪存设备IO软件的设计与实现 闪存作为最常用的嵌入式存储设备，其管理和访问技术对整个系统的性能有着较大的影响。目前嵌入式系统中广泛采用的闪存管理软件在可移植性、灵活性方面都存在不足。因此本文在分析了这些管理软件现存问题的基础上提出了一种比较合理的闪存I/O软件分层结构，并通过对软件的模块化设计与实现证明了该分层结构在移植性、通用性方面的优势。
(Embedded Systems Flash software equipment IO Design and Implementation of flash memory as the most commonly used embedded storage equipment, its management and technical visit to the performance of the whole system have greater influence. Embedded systems currently widely used in flash memory management software portability and flexibility are lacking. Therefore Based on the analysis of these problems existing management software based on a more reasonable Flash I/O software pm layer structure, and through a modular software design and implementation proved that the hierarchical structure of the transplant, universal respect.)
