| Abstract: | 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. |
