What is an embedded system?
Embedded system is used to control or monitor large equipment, such as machines, equipment, factories, etc. Taking application as the center and computer technology as the basis, the software and hardware can be customized to meet the strict requirements of application system for special computer system in terms of function, reliability, cost, volume and power consumption.

Characteristics of embedded system
Embedded system needs to be closely combined with application, which has strong specificity and must be reduced and utilized reasonably according to the actual system requirements. A knowledge integration system that combines advanced computer technology, semiconductor technology and electronic technology with specific applications in various industries.
The kernel of embedded system is very small. Because the embedded system is widely used in small electronic devices, the system resources are relatively limited, so the kernel is much smaller than the traditional operating system.
Embedded systems are streamlined. Generally, there is no obvious difference between system software and application software in embedded system, and its functional design and implementation are not required to be too complicated, which is conducive to controlling the cost of the system and realizing the security of the system.
