Embedded systems have undoubtedly become one of the hottest and most promising IT application fields.

Embedded technology is a system technology centered on applications and based on computer technology, which directly burns software into hardware rather than installing it on external storage media. Namely, transplanting the operating system onto existing hardware, allowing the operating system to manage software and hardware resources, reducing the coupling between software and hardware, and developing upper level applications on top of the operating system while developing lower level applications under the operating system.
Embedded technology originated from microcontroller technology and is the core of various digital electronic and electromechanical products, mainly used to achieve functions such as control, monitoring, or management of hardware devices. About 90% of the development in various industries of computer applications entering the 21st century will involve embedded development. The annual growth rate of the global embedded software market exceeds 12.5%, and the industrial annual output value brought by embedded systems reaches one trillion US dollars. In the next three years, the embedded software industry will maintain a compound annual growth rate of over 40%.
Embedded technology is a specialized computer system technology that is centered around applications, based on computer technology, and has customizable software and hardware. It is suitable for application systems that have strict requirements for functionality, reliability, cost, size, and power consumption. An embedded system is a complete computer system that includes hardware and software. Its definition is: "An embedded system is an application centric, computer technology-based, and software and hardware customizable specialized computer system that is suitable for application systems with strict requirements for functionality, reliability, cost, size, and power consumption." The computer used in an embedded system is a specialized microprocessor embedded in the controlled object, but its functionality is more specialized than that of a general-purpose computer. It has a specially designed, suitable computing speed, high reliability, and lower comparative cost for a certain aspect that a general-purpose computer cannot possess.
With the increasing complexity of embedded systems and exponential growth in the complexity and scale of software ecosystems, the implementation of artificial intelligence has accelerated the increase in software ecosystem complexity. Software engineering, open source software, and software quality will become the focus of embedded software. Especially for software systems applied in high security fields such as aerospace, automotive, and finance, software design and certification for safety, reliability, and trustworthiness are particularly important. The country has invested heavily in trusted software, and has made remarkable achievements in the development of application software in the fields of finance, Internet, aerospace, etc.
Embedded development is the process of porting operating systems between software and hardware. The operating system can manage software resources and hardware resources, achieving isolation between software and hardware. For example, if you want to run a camera in hardware, first let the software issue corresponding instructions to the operating system, and the operating system controls the hardware. The hardware returns data to the operating system, and the operating system then returns data to the software. In this way, when developing software, we do not need to understand the working principle and structure of the hardware. As long as the operating system does not change, hardware changes will not affect the software.
With the increasingly widespread application of embedded systems in high security fields such as finance, aircraft, automobiles, and nuclear power, higher requirements are being placed on the security, reliability, and trustworthiness of embedded systems. Various industries have developed various software and hardware development specifications, standards, and process control systems, resulting in the development of corresponding processors and operating systems. With the continuous increase in application complexity and the expansion of embedded system scale, design methods that meet the characteristics of security, reliability, and trustworthiness still need to be further explored. The application will continue to drive the collaborative and sustainable development of various embedded technologies.
Industrial automation equipment based on embedded chips will make significant progress. Currently, there are a large number of 8-bit, 16 bit, and 32-bit embedded microcontrollers in application. Networking is the main way to improve production efficiency and product quality, and reduce human resources, such as industrial process control, digital machine tools, power systems, grid safety, grid equipment monitoring, and petrochemical systems. For traditional industrial control products, low-end models often use 8-bit microcontrollers. However, with the development of technology, 32-bit and 64 bit processors have gradually become the core of industrial control equipment and are bound to make significant progress in the coming years.
