本文介绍了应用FPGA实现对高速A/D转换芯片的控制电路，介绍了这一控制的设计思想，并提出了通过双口RAM实现FPGA与慢速度的单片机进行双机数据通信处理的解决方案。-　　　Data acquisition is an item of indispensable technology which is essential to the industrial control system. As the increasing need for speed performance of the data collection requirements, FPGA technology came into being. This paper introduces the high-speed A/D converter by using FPGA chip control circuit detailing, discussing the design of the control circuit, at the same time submitting the FPGA through dual-port RAM and slow-speed single-chip dual-computer data communications solutions. FPGA and Single-chip microcomputer mutual coordination work, control the data acquisition system, and Single-chip microcomputer with rich peripherals can be extended accordingly. The circuit of the design that use VHDL language to complete. Through the program designing and testing, the voltage information which is showed in the PC through serial port transmission collected ultimately. It is successful to realize the mutual communication between FPGA and single-chip microcomputer.
