摘　　要：提出了一种基于USB和FPGA的高性能数据采集设计方案并详细介绍了其软硬件实现方法。USB12016采集卡包括模拟输入、A/D转换、数据缓存、FPGA控制电路和USB总线接口等, 在一张卡上实现了8 通道模拟信号调理、采集、处理, 并可实现多卡同步触发采集。A design scheme of high - performance data acqui sition based on USB and FPGA and its hardware and software implementation are in troduced. The data acquisition card is composed of analog signals inputs, A/D converter, memory, USB Controller and FPGA. In this project, signal conditioning, data acquisition and processing are implemented on a single board and high precision synchronization - triggering acquisition of multi - card is a plus. This system has succeeded achieving signal sampling, analyzing and processing.
