摘要
论文首先从内核性能和安全性的角度分析驱动程序对微内核与单体内核的影响;然后讨论硬件抽象层对驱动抽象能力的影响以及与移植性及内核大小的关系;分析传统UNIX系列与Windows NT操作系统内核结构以及驱动模型优缺点;最后介绍一个构件化驱动模型的特点。该模型基于构件装配运行平台技术,运行在和欣2.0操作系统平台上。驱动模型底层是一个合适的硬件抽象层,方便移植,用户态程序可以灵活地调用驱动程序。
First,this paper analyses how micro kernel and monolithic kernel influence device drivers in the aspects of kernel performance and security.Second,it discusses the relationship among hardware abstraction layer and drivers' abstraction,portability and the size of the kernel,analyses the UNIX series and Windows NT operating system,and summarizes specification of their kernel architecture and device drivers model.Last,it develops a driver model based on component.The driver model runs in Elastos OS with a proper hardware abstraction layer,and the user-mode program can call the drivers easily and agilely.
