摘　　要：在高速实时信号处理系统中常采用 FPGA+DSP 的架构,根据各自的优点,FPGA 主要做前端信号处理和系统控制。结合具体工程项目,分析设计如何在 FPGA 中实现中频正交采样(DDC),FPGA 如何与 TS201实现高速链路口通信,以及如何在 FPGA 中实现多路信号并行实时处理。In high-speed real-time signal processing systems, FPGA＋DSP architecture is often used. In accordance with their respective advantages, FPGA is often used as front-end signal processing and system control. In combination with concrete projects, this paper analyzed how to design IF quadrature sampling （DDC） in FPGA, how to achieve communication between FPGA and TS201 use link-port, and how to achieve multiple real-time signal parallel processing in FPGA.
