单片机是嵌入式系统。 单片机一般是4位、8位或16位的数据总线，一般内置存储器，不运行操作系统，侧重于低成本，主要应用与工业控制等领域；而ARM嵌入式系统是32位的数据总线，运算速度快，外接大容量存储器，能运行操作系统以适合多种应用。
嵌入式系统与通用计算机之间的区别：通用计算机系统采用标准化、模块化的设计，其技术要求是高速、海量的信息处理，技术发展方向是处理速度、总线宽度、存储容量的无限提升。而嵌入式系统怎采用针对性较强的专业化设计，技术要求是满足具体应用，技术发展方向是在保证应用系统的技术要求和可靠性的前提下，尽可能减小成本、体积和功耗。

Microcontroller embedded systems. SCM is a 4-bit, 8-bit or 16-bit data bus, built-in memory, not running the operating system, focusing on low-cost, major applications and industrial control fields; ARM embedded system is a 32-bit data bus, fast, external mass storage, can run the operating system to suit a variety of applications.The differences between embedded systems and computer: computer system uses a standardized, modular design, its technical requirements are high-speed, mass information processing, technical direction is the processing speed, bus width, the unlimited storage capacity upgrade. Design of embedded systems targeted specialized, technical requirements is to meet the specific application, technical direction of development is to ensure the application of technical requirements and the reliability of the premise, minimizing the cost, size and power consumption.

SCM is embedded system. Single chip microcomputer is the 4 bit, 8 bit or 16 bit data bus, general built-in memory, do not run the operating system, focusing on the low cost, the main application and industrial control and other fields; and ARM embedded system is the 32 bit data bus, computing speed, external large capacity memory, can run the operating system for a variety of applications. The difference between the embedded system and the general computer: the universal computer system uses the standard, the modular design, its technical requirement is the high speed, the massive information processing, the technical development direction is processing speed, the bus width, the storage capacity.And the embedded system can be applied to the specific application, the technical development direction is to ensure the application system of the technology requirements and reliability, as far as possible to reduce cost, volume and power consumption.
