具有PCI總線接口的通用嵌入式主板設計

嵌入式系統(tǒng)和PCI 設備的廣泛應用，使得越來越多的產(chǎn)品需要在這兩種先進技術共有的平臺上運行。文章以嵌入式視頻傳輸系統(tǒng)設計為例介紹了以ARM9 處理器S3C2510A 為主芯片、具有2 個PCI 插槽的嵌入式系統(tǒng)主板的設計思想，描述了系統(tǒng)的硬件構成、Boot loader 的移植以及設備驅(qū)動程序的編寫方法。該主板的應用可以避免嵌入式系統(tǒng)的重復開發(fā)，使各種PCI 設備卡方便的利用嵌入式系統(tǒng)管理模式運行。

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.
