【摘要】 随着信息技术与计算机网络的迅速发展，对具有良好网络功能的嵌入式系统的需求日益迫切。该文在分析嵌入式系统中实现网络底层驱动所需要注意的问题之后，系统地介绍了已经实现了的一个网络底层驱动的相关数据结构和算法，并以与Linux系统相比较的方法给出了我们研制的MiniCore操作系统的网络驱动性能。更多还原

【Abstract】 With the quick development of information technology and computer network, the demands of embedded system with good network functions are very imminent. After analysing some problems in implementing physical level driver for network in an embedded system, this paper systematically introduces the data structures and algorithms of the physical level driver for network in the embedded system——MiniCore, and gives out network driver performances of MiniCore by comparing with Linux system.更多还原
