基于多功能单片学习机的 NAND FLASH 驱动的设计The design of NAND FLASH driver based on a Multifunction SCM learning machine摘 要基于多功能单片学习机的 NAND FLASH 驱动包括两部分：多功能单片学习机和 NAND FLASH 存储器。本论文首先介绍了多功能单片学习机的软/硬件设计，该学习机利用自动程序切换电路，使得同一片单片机既可以运行系统程序，又可以运行用户程序，实现程序代码的在线下载。学习机外部扩展了大量的硬件资源，丰富的系统硬件资源构成了各种实际应用电路，通过万能扩展接口可以很方便地仿真外部应用电路和扩展用户应用电路。然后，着重介绍了 NAND FLASH 扩展板的软/硬件设计，通过多功能单片学习机实现对NAND FLASH 的读、写时序。关键字：多功能单片学习机 自动切换电路 NAND FLASH AbstractBased NAND FLASH multi-functional single-chip learning machine drive consists of two parts: a multi-functional single-chip learning machine and NAND Flash memory. This paper introduces the hardware / software design, multi-functional single-chip learning machine with automatic switch circuit, so with a microcontroller can either run the system program, you can run the user program, the online download of the program code. external learning machine expanse a lot of hardware resources, hardware system resources poses practical application circuit, through the universal expansion interface can easily simulate the external application circuit and extend the user application circuit. Then focuses on the the NAND FLASH expansion board hardware / software design, achieved through a multi-functional single-chip learning machine NAND FLASH read and write timing.Key word: Multifunction SCM learning machine；automatic switch circuit ；NAND FLASH； 目录摘 要.................................................................................................................................................IABSTRACT...........................................................
