What is an embedded system?

Embedded system is a special computer system that is completely embedded in the controlled equipment and designed for specific applications.

It can be used to control or monitor machines, equipment, factories and other large-scale equipment, and is applied to industrial control, traffic management, home intelligent management and other fields. Unlike general computer systems such as personal computers, embedded systems usually perform predefined tasks with specific requirements.

Embedded system equipment usually consists of embedded computer system and execution equipment. Embedded computer system is the core of the whole embedded system, which consists of hardware layer, middle layer, system software layer and application software layer. The embedded system has a history of nearly 30 years, from the appearance of single chip microcomputer in 1970s to the large-scale application of various embedded microprocessors and microcontrollers.

strong function

Embedded system is user-oriented, product-oriented and application-oriented, and it must be combined with specific applications to have vitality and advantages, that is, embedded system is closely combined with applications and has strong specificity, so it must be reasonably reduced and utilized in combination with actual system requirements. Embedded system is the product of advanced computer technology, semiconductor technology and electronic technology combined with specific applications in various industries.

This determines that it must be a technology-intensive, capital-intensive and highly decentralized innovative knowledge integration system. Therefore, to set foot in the embedded system industry, we must have a correct positioning. For example, Palm occupies more than 70% of the PDA market, because it is based on personal consumer electronic products and focuses on developing graphical interfaces and multi-tasking management, while Fenghe's Vxworks is applied to Mars vehicles because of its high real-time performance and high reliability.
