Design of Multi-channel Data Acquisition and Speed Variable Transmission System Based on FPGA

本文设计了一种多通道数据采集与发送速率可变的系统,采用FPGA芯片EP4CE10F17C8N作为核心控制器件,利用Verilog HDL在QUARTUS Ⅱ 13.1平台上对数据采集模块、数据存储模块、数据发送模块以及系统控制模块进行描述,并使用Modelsim仿真工具对各个模块进行模拟仿真,最后通过AC620开发板测试,实现了多通道的数据采集和速率可变的串口发送功能。

In this paper, a multi-channel data acquisition and transmission rate variable system is designed. This system adopts FPGA chip EP4CE10F17C8N as the core control device. Then Verilog HDL was used to describe the data acquisition module, data storage module, data transmission module and system control module on QUARTUS Ⅱ 13.1 platform. And Modelsim simulation tool is used to simulate each module.Finally, through the test of AC620 development board, the function of multi-channel data acquisition and serial port transmission with variable rate is realized.
