嵌入式系统的硬件组成部分是以嵌入式处理器为中心，由存储器、V/O设备、通信模块以及电源等必要的辅助接口组成的。嵌入式系统是量身定做的计算机应用系统，它不同于PC机的组成，在实际应用中的嵌入式系统硬件配置非常精简，除了微控制器和基本的外围电路以外，其余的电路都可根据需要和成本进行裁减、定制。

嵌入式系统硬件核心是嵌入式微处理器，有时为了提高系统的信息处理能力，常常外接DSP和DSP协处理器(或者选用内部集成了DSP模块的微处理器)，以完成信号处理。

随着计算机技术、微电子技术、应用技术的不断发展及纳米芯片加工工艺技术的发展，以微处理器为核心的集成多种功能的SOC系统芯片已经成为嵌入式系统的核心。

这些SOC集成了大量的外围USB，UART，以太网，AD/DA等功能模块，能很好地满足各种系统的需要。以SOC为核心、用少的外围部件和连接部件构成一个应用系统，满足系统的功能需求是嵌入式系统发展的一个方向。

The hardware component of embedded system is centered on embedded processor, and consists of necessary auxiliary interfaces such as memory, V/O device, communication module and power supply. Embedded system is a customized computer application system, it is different from the composition of the PC, in the actual application of the embedded system hardware configuration is very simple, in addition to the microcontroller and basic peripheral circuits, the rest of the circuit can be reduced according to needs and costs, customized.

Embedded system hardware core is embedded microprocessor, sometimes in order to improve the information processing ability of the system, often external DSP and DSP coprocessor (or choose internal integrated DSP module microprocessor) to complete signal processing.

With the development of computer technology, microelectronics technology, application technology and nano-chip processing technology, SOC system chip with microprocessor as the core has become the core of embedded system.

These SOCs integrate a large number of peripheral USB, UART, Ethernet, AD/DA and other functional modules, which can well meet the needs of various systems. It is a development direction of embedded system to build an application system with SOC as the core, use less peripheral parts and connecting parts, and meet the functional requirements of the system.
