（1）嵌入式操作系统的作用是什么？请举出3种常见的操作系统。
答：用于管理存储器分配、中断处理、任务间通信和定时器响应，以及提供多任务处理等功能。嵌入式操作系统，大大地提高了嵌入式系统硬件工作效率，并为应用软件开发提供了极大的便利。3种常见的操作系统：WinCE、Vxworks、uClinux
（2）什么是交叉编译工具：交叉编译是一个平台上生成另外一个平台上的可执行代码。使用交叉编译工具有很多种原因，有时是因为目标平台上不允许或不能够安装所需的编译器；有时是因为目标平台资源贫乏，无法运行所需编译器；有时是因为目标平台还没有建立，连操作系统都没有，根本无法运行编译器。

(1) what is the embedded operating system? Please list 3 common operating systems.A: to manage memory allocation, interrupt handling, task, timer response and communications, as well as providing features such as multi-tasking. Embedded operating systems, greatly raised efficiency in embedded system hardware and provides great convenience for application software development. 3 common operating system: WinCE, and Vxworks, and uClinux(2) what is a cross compilation tool: cross-compilation is a platform built on a platform of executable code. Use a cross compilation tools there are a number of reasons, sometimes because the target platform does not allow or not be able to install the required compiler sometimes because the target platform for resource-poor, unable to run the compiler required; sometimes because the target platform has not established, not even my operating system, it is impossible to run the compiler.

(1) what is the role of the embedded operating system? 3 common operating systems, please. It is used to manage memory allocation, interrupt handling, inter task communication and timer response, as well as to provide multi tasking and other functions. Embedded operating system, greatly improving the efficiency of the embedded system hardware, and provide a great convenience for the application of software development. 3 common operating systems: WinCE, Vxworks, uClinux
(2) what is the cross compiler tool: cross compilation is a platform to generate another executable code on the platform. There are many reasons for using cross compiler tools,Sometimes it is because the target platform is not allowed to install the required compiler; sometimes because the target platform is poor, unable to run the required compiler; sometimes because the target platform is not yet established, even the operating system is not, simply can not run the compiler.
