基于SOPC的PCI数据采集卡的设计与实现

针对传统数字接收机数据采集模块因集成化程度高而造成资源浪费且缺乏灵活性的问题,依据PCI总线支持突发传输特性和FPGA可编程的灵活性,编写了PCI接口的驱动程序,设计并实现了基于FPGA可控制的高速数据采集卡.采用Ahera公司的可编程逻辑器件EP3C10F256C8N在SOPC Builder环境下完成PCI桥的快速开发,并利用WinDriver工具在Windows XP系统下实现设备的驱动程序开发,完成从模式数据突发传输和设备中断的功能.该数据采集卡开发周期短、开发成本低,尤其适用于用户的不同需求,具有较高的实用价值.

Design and Realization of a PCI Sampling Card Based on SOPC

As data sampling module in traditional digital receivers may waste logical resource and be lack of flexibility, a high speed data sampling card based on FPGA and PCI bus is designed and realized. To meet the request, EP3C10F256C8N is chosen as FPGA. PCI Bridge is implemented quickly by SOPC Builder. Using the development tool of WinDriver, the driver program is developed for devices running on Windows XP, which completes the functions of data transfer in target burst mode and device interruption. With shor-ter development cycle and lower cost, the card can meet various requirements and has practical value.
