NIOS-Ⅱ处理器的大容量数据采集存储系统设计

以NIOS-Ⅱ处理器为核心,构建一个SOPC系统,控制CH376文件管理芯片,将采集的数据以文件形式写入U盘中,以满足现场大容量数据的快速采样存储的需要。由于FPGA具有输入输出引脚多、运行速度快和可编程的特点,只要软件稍作修改,即可将数据存入SD卡中。经过软硬件的综合测试,能成功实现系统各项功能。

Mass Data Collection and Storage System Based on NIOS-II Procession

The paper takes NIOS-II processor as the core and constructs an SOPC system to control the CH376 file management chips. It writes the collected data down in U disks in files, meeting the site large-capacity data storage needs of fast sampling. FPGA has the ad vantages of more input and output pins, run faster and programmable, as long as the software makes some modifications ,it can store the data to SD card. After comprehensive testing of hardware and software, various functions of the system can be successfully realized.
