基于FPGA的模数转换芯片MAX191控制器的设计

Design of Controller for Digital-To-Analog Conversion Chip MAX191 Based on FPGA

MAX191是MAXIM公司生产的低功耗、高速度、高精度的12位AD转换器,采用型号为EP4CE6E22C8的FPGA芯片对MAX191进行实时采样控制,并将采集到的数据通过RS232发送至分辨率为(800×400)像素的LCD上实时显示。整个设计过程采用硬件描述语言Verilog在EDA平台QuartusⅡ14.0上进行。

The MAX191 is a low-power,high-speed,high-precision 12-bit AD converter that produced by MAXIM.In this design,using FPGA chip that model is EP4CE6E22C8 for real-time sampling control of MAX191,and sending the collected data through RS232 to the LCD with a resolution of(800×400)pixels for real-time display.The whole design process uses the hardware description language Verilog to proceed on the EDA platform QuartusⅡ14.0.
