基于PCI-E接口的高速数字信号处理系统设计

The design of high-speed digital signal processing system based on PCI-E interface

为了满足目前实时信号处理要求,利用ADSP-TS201和Virtex4系列FPGA构建高速数字信号处理系统,采用点对点互连和紧耦合结构设计,利用FPGA自定义LVDS接口实现板级互连,通过PCI-E接口与上位机通信,具有良好的可扩展性。文章介绍了系统的结构、原理及PCB设计。

In order to meet the current requirements of real-time signal processing,the ADSP-TS201 and Virtex4 series FPGA is used to build high-speed digital signal processing system.Tightly structural coupled with point to point interconnects with a custom FPGA board-level interconnect LVDS interface through the PCI-E interface to communicate with the host computer,is used to design the system,has good scalability.This paper introduces the system structure,principles,and PCB design.
