Design of multichannel data acquisition module based on FPGA

With the rapid development of FPGA, it is widely used in more fields by virtue of its high flexibility and high parallel computing efficiency. In order to meet the accuracy, real-time and synchronization of data acquisition, this paper designs a multi - channel data acquisition module based on FPGA. In this paper, the Kintex-7 series FPGA is used as the main chip. By using 8 AD chips, 16-channel data acquisition is achieved. Functions such as data buffering, data processing, and UDP network transmission are also realized. After experimental tests, the design has the characteristics of strong synchronism, high precision, and good reliability.
