摘要：設備驅動程序復雜度較高，導致其體量龐大，開發效率低下，且是導致操作系統崩潰的主要源頭。為了提高設備驅動程序的開發效率，減少設備驅動程序中的錯誤，提高其質量，本文提出了一種模塊化設備驅動開發方法，并運用這一方法針對以太網網卡類設備設計了模塊化設備驅動開發框架。接著對該框架進行實例化，為四塊網卡構造出Linux和VxWorks兩種操作系統下的網卡設備驅動程序以說明方法的可行性和有效性。
關鍵詞：設備驅動；復雜性；可復用性；質量；模塊化開發方法

Abstract：The huge volume and error-prone characteristics of device drivers is determined by their intrinsic complexity. In order to raise the efficiency of device drivers development and improve the quality of device drivers by reducing errors in device drivers, we propose a modular approach for device driver development. Adopting this approach, we developed a modular device driver development framework for Ethernet devices. Then using the framework, we developed drivers for the four Network Interface Cards in Embedded Linux and Vxworks to prove the feasibility and effectiveness of our approach.
Key words：device driver; complexity; reusability; quality; modular approach
