嵌入式系统具备下列特性：

1. 通常只执行特定功能，这一点与一般桌上型办公设备或数据库系统有很大区别。

2. 以微电脑与周边器件构成核心，其规模可在大范围内变化，如从8051芯片到x86芯片。

3. 要求严格的时序和稳定性，这是因为在机器控制的大型系统中，程序运行稍有差错则可能使得整个系统失去控制，甚至酿成灾害。

4. 全自动操作循环-Embedded systems have the following features: 1. Usually perform a specific function, this office equipment or with a regular desktop database system quite different. 2. Microcomputer and peripheral devices to form the core of its size can change in a wide range, such as the chips to x86 chips from 8051. 3. Demanding timing and stability, this is because large-scale systems in machine control, the program runs a little mistake might make the whole system out of control, or even lead to disaster. 4. Automatic operating cycle
