摘　　要：介绍了一种针对高速CCD 图像采集的嵌入式实现方案,通过引入 32Bit/66MHz PCI总线标准,以及有关的缓存组织等技术,解决了数据采集的速度和小型化问题,使得该项技术可适用于更为宽泛的应用环境。在此基础上,给出了嵌入式系统中 PCI总线的配置过程,以及软硬件设计中需要注意的问题。该方案对于嵌入式高速图像记录技术中系统结构的设计也是一种有益的探索。A scheme for the implementation of high-speed CCD image sampling with embedded system is presented. Through introducing 32Bit/66MHz PCI bus and relevant buffer management, problems associated with sampling speed and miniaturization can be resolved, thus promoting the application of this technology to a wide fields. The configuration processes for PCI bus and some importance for designing the software are also given in this paper. The scheme benefits the exploration of designing an embedded high-speed image recording system.
