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.
