摘　　要：在AMBA AHB总线上实现NAND FLASH控制器有多种方案。为使其具有更好的兼容性,既能支持主流型号NAND FLASH的各种命令,同时又兼顾到读写效率,该设计根据NAND FLASH本身的操作特点,提出一种软硬件划分的设计方案,以软硬件结合的方式设计出NAND FLASH控制器。该设计通过系统级仿真,功能符合NAND FLASH操作规范。There are many kinds of methods to implement the NAND FLASH controller on the AMBA AHB general bus. In order to make it has a better compatibility which can support all kinds of commands of the primary NAND FLASH in the market,at the same time it has a high access efficiency,according to the characteristic of NAND FLASH operation, here gives a kind of software/hardware partition solution of implementing the controller by both hardware and software way. This design has past the system simulation and all functions accord with the NAND FLASH specification.
