基于SCA嵌入式平台的PCI设备驱动设计

PCI Device Driver Design Based on SCA Embedded Platform

为了克服传统通信系统成本高昂、功能单一、维护升级困难等缺点,SCA(软件通信体系结构)采用标准化的软件构件思想,有效提高了无线通信系统的软件复用程度,节省了设计开发成本,缩短了新技术验证和实现周期。文中提出了一种基于SCA嵌入式平台的PCI(外部设备互连)设备驱动设计方法。介绍了该平台的PCI总线结构、各PCI设备的功能及其驱动程序的设计流程和实现过程。该驱动设计具有模块化、标准化、可移植等特点。

In order to avoid high cost, few function, difficulty to maintain and upgrade in the traditional communication system, the SCA （Software Communication Architecture） uses standard software component concept to support efficient reusability of the wireless communication systems, lower development cost , have a shorter cycle of validation and implementation of a new technique. This paper implements a PCI device driver on an embedded system platform based on the SCA specification. We present the architecture of PCI bus, the function of each PCI device, the design flow and implementation of PCI device driver on the SCA embedded platform. The driver design has features of modularity, standardization and portability.
