通過對Windows和Linux環(huán)境下設(shè)備驅(qū)動程序設(shè)計模型的比較，結(jié)合通信領(lǐng)域嵌入式系統(tǒng)的特點，提出了嵌入式通信系統(tǒng)設(shè)備驅(qū)動程序設(shè)計標(biāo)準(zhǔn)化的構(gòu)想；通過參考常用的設(shè)備驅(qū)動程序的設(shè)計思想和設(shè)計模型，制定了嵌入式通信系統(tǒng)設(shè)備驅(qū)動程序的分層結(jié)構(gòu)，統(tǒng)一了底層驅(qū)動程序?qū)ι蠈討?yīng)用或管理程序的接口，屏蔽底層的硬件特性，實現(xiàn)了驅(qū)動程序的規(guī)范化、標(biāo)準(zhǔn)化；在VxWorks開發(fā)環(huán)境下，對設(shè)計標(biāo)準(zhǔn)進(jìn)行了詳細(xì)解析，并闡述了該標(biāo)準(zhǔn)制定的原因和意義。
This paper introduces the design standard of the embedded communication system device driver and the reason for proposing it. According to characteristics of the embedded communication system and compared with the design model of device driver in Windows and Linux, the architecture of embedded communication system device driver has been proposed. It can make the driver design much specifically and effectively. The driver design standard has been expatiated in VxWorks referring to specification of general device driver and development experience.
