嵌入式系统这两年来的发展主要表现为三个特征:操作系统多样化及客户化、芯片品牌种类多样化和上网方式多途径。 在操作系统方面,由于信息家电的需求增大,将使得嵌入式操作系统有极大的发展,包括win CE,Vxworks,PALM,Linux等等,而这其中以Linux为代表的开放源码软件将有广阔的发展空间,由于不同的信息家电会有不同的功能定制,这就需要不同的厂商甚至最终用户可以随意方便的更改自己手中的产品功能,而开放源码的软件给厂商及用户提供了最大的开发和 Embedded system development over the past two years mainly for the three characteristics: the operating system diversification and customization, diversification of chip brands and ways to access the Internet. In the operating system, due to the increasing demand for information appliances will make great progress in embedded operating systems, including win CE, Vxworks, PALM, Linux, etc., of which the open source software represented by Linux will have The vast space for development, due to different information appliances will have different features customization, which requires different manufacturers or even end-users can easily change their own hand product features, and open source software to manufacturers and users with the largest Develop and
