摘要
NOR Flash用于存储运行程序和应用数据,在嵌入式系统中应用广泛。针对NOR Flash的文件系统较为臃肿,在内存较小的嵌入式系统中无法正常工作,导致NOR Flash的读写方式为直接地址访问,人为地分配地址空间,管理数据不方便且容易出错。为解决这一问题,设计了一套针对NOR Flash的低内存占有率的存储访问分区管理方法,满足嵌入式系统中原始数据、静态数据和动态数据的管理要求。
NOR Flash is used to store running programs and application data,and is widely used in embedded systems.The file system for NOR Flash is relatively bulky and cannot function properly in embedded systems with small memory.It causes that the reading and writing method of NOR Flash is direct address access,address space is artificially allocated,and data management is inconvenient and prone to errors.To solve this problem,this paper designs a set of storage access partition management method with low memory usage for NOR Flash,which meets the management requirements of raw data,static data and dynamic data in embedded systems.
