    1 嵌入式系统，微控制器，与ARM

     

    1.1什么是嵌入式系统？

    微处理器不仅仅存在于通用计算机中，也可以安置在一些不需要计算的设备内部，比如洗衣机，摄像机。微处理器常常可以控制这些产品。因为这类产品的微处理器镶嵌在内部，所以称这类产品为嵌入式系统。

    许多情况下，微处理器更倾向于关注控制，所以在嵌入式系统中的微处理器相对于通用计算机中的处理器逐渐发展出不同的特性，这些称为微控制器。

    我们编写一个高层语言（HLL）编译器的计算机程序会读取我们的程序，把程序编译成为一系列的指令集，一些列的指令集合被转化为可以下载到程序储存器中的二进制代码。

    c语言的上层语言是c++，是一种在嵌入式开发中经常使用的高级语言。

    1.4进入ARM的世界

    cortex微处理内核是一系列杰出的32位ARM处理器。

    ARM公司开发出一系列有效的微处理器和微控制器设计，兵并广泛的用于嵌入式系统。
