摘　　要：设计的基于SDHC(secure digital high capacity)卡阵列的大容量存储系统,能够连续、大容量地存储由DSP(digitalsignal processor,数字信号处理)传递来的数字信息.系统采用基于DSP、MSP430单片机和多片SDHC卡的设计方案.其中以DSP作为核心芯片,负责数据的采集和存储管理,以SDHC阵列作为存储介质,以FAT32文件系统作为存储形式,采用单片机负责电路的通信和控制.此外,系统集成读卡功能,存储在SDHC阵列中的数据可以通过USB2.0接口高速地读取.运行测试结果表明,系统工作稳定,各项性能指标均可以达到设计要求.In this paper, high capacity, continuous signal acquisition and automatic storage system is designed based on DSP, MSP430 MCU and several SDHC cards. DSP as the core chip of the system is responsible for data acquisition and storage, the SDHC card array is used as memory media, FAT32 file system is used as format of storage, and MCU takes charge of communication and controL In addition, the system integrates card reader so that SDHC a card array can be accessed via USB2.0 interface fast. The result of performance test indicated that the system can work steadily and meet the design in all performance indexes in practice.
