Embedded motherboard is generally understood as the CPU board embedded in the device for control and data processing, that is, the "brain" of the device. Embedded into the device, of course, there will be more stringent requirements on the size and power consumption of the motherboard (the heat dissipation of the embedded motherboard). There are two standard embedded system architectures, RISC processor and CISC processor.

Embedded motherboards are divided into two common categories:

1. Based on the X86 embedded motherboard, Intel's X86 processor belongs to the CISC architecture (generally using INTEL, AMD, via, or other manufacturers' X86 chips, etc.)

2. ARM embedded motherboard based on RISC (authorized by ARM, each chipmaker has its own special function). Embedded arm boards are generally on-board CPU, while motherboards based on x86 CPU are not necessarily.

Embedded technology has developed rapidly in recent years, but the embedded industry involves a wide range of fields, and the characteristics between them are also quite obvious. For example, many industries: mobile phones, PDA, vehicle navigation, industrial control, military, multimedia terminals, gateways, digital television, etc.; the main application environment of embedded motherboard is in finance, petrochemical, geophysical exploration, field portable, environmental protection, military industry, electric power, railway, highway, aerospace, subway and so on.

Application field of embedded motherboard

Medical instrument

The application rate of embedded system in medical instruments is very high. In the design process, reprogramming the embedded system according to the need can avoid the cost of front-end NRE, reduce the order quantity related to ASIC, and reduce the huge risk of chip trial production. In addition, with the development of the standard or when the demand changes, it can be updated on site, and designers can repeatedly use the common hardware platform to establish different systems and support various functions on the basis of a basic design. as a result, the production cost is greatly reduced. So that the product has a longer life cycle, can protect medical equipment will not be too fast out of date, the medical industry product life cycle is relatively long, so this characteristic is very important. Modern digital medical equipment includes not only diagnosis and treatment equipment, but also data storage server and interface software. Embedded system can provide advanced technical support for the design, production and use of medical instruments and equipment.

Military and national defense field

Military defense has always been an important application field of embedded systems. In the 1970s, embedded computer systems were used in weapon control systems, and later in military command and control and communication systems. At present, embedded systems can be seen in all kinds of weapon control devices (artillery, × × and intelligent × × guidance detonation and other control devices), tanks, warships, bombers, various military electronic equipment, radar, electronic countermeasures equipment, military communications equipment, and various special equipment for field command operations.

Robot

With the popularization and development of embedded system and robot technology, the function of robot body is becoming more and more modular, intelligent and miniaturized. At the same time, the price of robots is also falling sharply, making them more widely used in military, industrial, family, medical and other fields. For more information, visit www.femrice.com.cn.
