在不同的应用场合,嵌入式系统呈现出的外观和形式各不相同。但通过对其内部结构进行分析,可以发现,一个嵌入式系统一般都由嵌入式微处理器系统和被控对象组成,如下图所示。其中嵌入式微处理器系统是整个系统的核心,由硬件层、中间层、软件层和功能层组成。被控对象可以是各种传感器、电机等,可以接受嵌入式微处理器系统发出的控制命令,执行所规定的操作或任务-In different applications, embedded systems and presents the appearance of different forms. However, the analysis by its internal structure, we can find an embedded system typically charged by the embedded microprocessor systems and objects, as shown below. Embedded microprocessor system which is the core of the entire system, from the hardware layer, middle layer, software layer and function layer. Controlled object can be a variety of sensors, motors, etc., can accept embedded microprocessor control system to issue commands to perform the required operation or mission
