基于PCI的视频信号发生器的实现方法

An Implementation Scheme of Video Signal Generator Based on PCI

提出了一种基于 PCI 总线的视频图像数据发送系统的设计和实现方法。主要介绍系统的硬件实现方法和软件的实现流程。该系统利用 PLX9054 作为 PCI 的接口芯片,用 FPGA 实现 9054PCI 接口芯片与发送系统总线之间的控制,D/A 转换芯片完成同步信号和视频图像数据的组合,并转换成模拟视频信号,作为发送系统的输出。该系统为图像跟踪与识别系统提供一个定量的性能测试设备。

An implementation scheme of PCI based video signal generators is proposed in this paper with emphasis on the method of hardware implementation and the flow of the software system. Plx9054 and FPGA are used respectively as the interface chip and the controller of the generator. A D/A chip is used to transform the digital image data to analog signals. The generator can be used as testing equipment for the target tracking system.
