中文摘要：

在数据采集系统中，往往采用单片机或者DSP进行控制，而在高精度线阵CCD的应用中，对像元输出信号进行快速采样、存储是很重要的一部分内容。针对这些问题，提出了基于SOPC的光谱数据采集系统的设计方案。该系统建立在Altera公司CycloneⅢ系列FPGA（EP3C10E144C8N）上，实现了CCD驱动电路和A／D采样控制电路，并选用USB接口芯片CY7C68013来共同完成数据的高速传输。实验结果表明，该系统集成度高、性价比高且能在短时间内实现，使用的新技术给光谱仪器设计领域带来新的亮点。

英文摘要：

MCU or DSP is widely used for control in the data acquisition system. In the application of high accuracy linear CCD, it is important to sample and store data quickly. In view of these questions, a design method of spectrum data acquisition system based on SOPC is proposed. The CCD driving circuit and A/D controller circuit on Altera＇s Cyclone III FPGA EP3C10E144C8N are realized, and the USB interface chip CY7C68013 is chosen to complete the high-speed data transmission together. Experimental results show that the system has high integration, high price/performance, and can be realized in a short time, the new technology brings a new spot to the design of spectrum instrument.
