基于NIOSⅡ的光纤以太网CCD相机系统设计

Design of Optical Fiber Ethernet CCD System Based on NIOSⅡ

光纤以太网络相机是目前最具前景的相机应用模式之一。设计了基于NIOSⅡ的光纤以太网相机系统,利用FPGA的NIOSⅡ内核对网卡芯片W3150A进行配置及驱动,实现图像采集模块与计算机通过TCP/IP协议实现网络传输数据。该相机系统能在1s之内完成一幅2MByte图像数据的网络传输,在速度上能满足系统的技术要求。文章介绍了系统的实现方案。

Optical fiber Ethernet camera is one of the most promising application modes of cameras. With the chip W3150A, which is configured and driven by NIOSⅡ core of FPGA, the data transfer between the image acquisition module and a computer is realized through TCP/IP. 2 Mbyte image data can be transferred within l s, which meets the technical requirement. The scheme based on NIOS Ⅱ is presented.
