FPGA片上多通道实时采集系统的设计

Design of Multi-channel Real-time Acquisition System Based on FPGA

阐述Xilinx 7系列FPGA内置的XADC硬核自带ADC,为FPGA片上完成多通道模拟信号采集提供条件。采用USB转UART芯片CP2102GM完成系统串口输出,进一步减少采集系统的体积,提高系统的可靠性。

This paper expounds the embedded XADC hard core of Xilinx 7 series FPGA with own ADC,which provides conditions for the completion of multi-channel analog signal acquisition based on FPGA.The USB to UART chip CP2102GM is used to realize the serial output of the system,which further reduces the volume of the acquisition system and improves the reliability of the system.
