【摘要】 在分析了原有实时场景产生器性能结构的基础上，根据新的技术要求，我们仔细分析了场景的生成过程，研究了软件部分和硬件部分的实现方案，完成了总体设计。新的技术要求增加了一个同步通路，为了满足系统的主要技术指标，我们研究了双路信号的同步方法，我们相应的改变了软件的部分设计和全部的硬件结构。经过调试和组装我完成了项目的合同要求。 在本文中讨论了系统的总体设计方案，叙述了软件系统和基于PCI总线的硬件系统。在硬件系统中我们采用PLX9054作为PCI接口控制芯片，由FPGA构成整个信息处理板的控制核心，并利用SAA7129把数字图像信号转换成模拟图像信号。着重讨论了硬件系统各功能模块的具体实现方法。更多还原

【Abstract】 According to the present requirement of technology standards, the generating process of real-time scenes is carefully analyzed; and based on the function of the previous scene generators, the realizing schemes of the software and the hardware are also discussed in this paper. In order to meet the main technology standard of the system, with the study on the generating, transmitting and output technology of two synchronization channels scene generator, the schemes of the software and the hardware are processed.By full usage of the software resources of computer, part of work of the scene generator is accomplished with Windows NT as the operating system.In the design of hardware, PLX9054 is used to realize the control of PCI bridge route, which greatly shortens the period of development. The hardware system with the composition of the PCI functional plug-in structure, realizes the real-time output of 10bit scene data whose resolution is 768*576 in the velocity of 25 frames per second. The new system required two synchronization channels. The synchronization of two channels is realized by two plug-in cared with the same synchronization source.更多还原
