摘要
本研究的目的是设计一个具有大容量的本地存储系统,容量大于64MB以上,可以实现热插拔,要求通信引脚少,功耗低,使用方便,类似于常用的U盘,便于携带。本设计采用MSP430F149单片机作为核心芯片,配以SMARTMEDIA卡作为存储卡,电源电路部分用TPS76033芯片,复位电路部分使用MAX809STR芯片。将单片机,存储卡,复位电路,电源电路构成一个完整的系统,这就是该设计的硬件部分。软件部分使用分时复用技术巧妙地分配存储阵列的地址,这样就解决了读,写,擦除时遇到的I/O输入输出端口不够用的问题。经过研究,使用以上硬件完全可以达到本地存储大数据量的目的,并且有功好耗低,体积小,处理速度快等诸多优点。该设计使得存储数据的方式变的灵活多样,解决了一般方法扩充方法所达不到的海量存储的效果。该设备可以应用在多方面,提高了人民的生活质量。

Abstract
This research goal is designs one to have the large capacity local memory system, the capacity is bigger than above 64MB, may realize inserts hotly pulls out, the request correspondence pin are few, the power loss is low, the easy to operate, is similar to monly used U plate, is advantageous for carries. This design uses MSP430F149 monolithic integrated circuit to take the core chip, matches by the SMARTMEDIA card took the memory card, the power circuit part with TPS76033 chip, repositions the electric circuit part to use MAX809STR chip. The monolithic integrated circuit, the memory card, repositions the electric circuit, the power circuit constitutes plete system, this is this design hardware part. The software part use time sharing multiplying technology assigns the memory array ingeniously the address, like this solved read, writes, when cleaning met I/O input the output port insufficient question. After the research, uses above hardware definitely to be possible to achieve local saves the great data quantity the goal, and actives consumes lowly, the volume is small, processing speed quick and so on many merits. This design causes the stored datum the way to change nimble diverse, has solved the mass memory effect which the general method expansion method could not achieve. This equipment may apply in variously, improved people's quality of life.
