具有PCI总线接口的通用嵌入式主板设计

嵌入式系统和PCI 设备的广泛应用，使得越来越多的产品需要在这两种先进技术共有的平台上运行。文章以嵌入式视频传输系统设计为例介绍了以ARM9 处理器S3C2510A 为主芯片、具有2 个PCI 插槽的嵌入式系统主板的设计思想，描述了系统的硬件构成、Boot loader 的移植以及设备驱动程序的编写方法。该主板的应用可以避免嵌入式系统的重复开发，使各种PCI 设备卡方便的利用嵌入式系统管理模式运行。

Abstract: With the wide application of embedded system and PCI devices, many products need to run on both platforms of embedded system and systems with PCI interface. The design of the embedded video transmission system, for example, is presented in the paper.
The hardware design of the embedded motherboard of 2 PCI slots with processor S3C2510A of ARM9; transplantation of Boot loader and methods of constructing device driver is also described. The application of the newly developed motherboard will eliminate the
necessity of repeated development of embedded system and kinds of ready-made PCI device can apply to the embedded system conveniently.
