树是由n(n≥0)个结点组成的有限集合T。n=0的树称为空树；对n>0的树，有:(1)仅有一个特殊的结点称为根结点，根结点没有前驱结点；(2)当n>1时，除根结点外其余的结点分为m(m>0)个互不相交的有限集合T1,T2，…，Tm，其中每个集合Ti本身又是一棵结构和树类似的子树。 -Tree is n (n ≥ 0) consisting of nodes finite set T. n = 0 of the tree known as the empty tree for n> 0 of the tree, there is: (1) has only one special node called the root node, root node there is no precursor node (2) when n> 1 when, with the exception of root node except the node is divided into m (m> 0) a finite set of mutually exclusive cross-T1, T2, ..., Tm, one of each set Ti is itself a structure and are similar subtree tree .

介绍uC/OS-II 在SkyEye上的移植分析.uC/OS-II 作为一个优秀的实时操作系统已经被移植到各种体系结构的微处理器上，也是目前较为常用的公开源码的实时内核。从这里入手学习嵌入式系统开发的基本概念，以及在 SkyEye 里构造一个可以运行的RTOS，能够使我们更深入地了解嵌入式开发的流程，在没有硬件的条件下也能对ARM的体系结构有个初步的认识。-on Phone/OS-II in the transplant SkyEye analysis .uC/OS-II as a excellent real-time operating system has been transplanted to various Architecture microprocessor, It is at present more commonly used open-source real-time kernel. From here start learning embedded system development of the basic concepts SkyEye Lane and the construction of an RTOS can run, enable us to a deeper understanding of embedded development processes, In the absence of hardware conditions can also ARM Architecture is a preliminary understanding.
