The Relationship between Embedded Technology and IT Specialty

The relationship between embedded technology and IT specialty Embedded system refers to a special computer system which is application-centered, based on computer technology, and can be tailored in software and hardware, and is suitable for application systems with strict requirements on function, reliability, cost, volume and power consumption. It generally consists of four parts: embedded microprocessor, peripheral hardware devices, embedded operating system and user applications, which are used to control, monitor or manage other devices.

In recent years, with the development of computer technology and integrated circuit technology, embedded technology has become increasingly popular, playing an increasingly important role in communication, network, industrial control, medical care, electronics and other fields. Embedded system has undoubtedly become one of the hottest and most promising IT application fields. With the huge industrial demand, the demand for talents in the embedded system industry in China is also rising, and embedded development will become one of the hottest and hottest occupations in the next few years.

At present, the hot professionals are all soft talents. However, the threshold of embedded system field is high, so embedded developers not only need to know the underlying software, but also have higher requirements for the professional level of software. The embedded talents needed in the market must have experience in C language programming, embedded operating system (embedded Linux or WinCE), core cutting experience, operating system value transfer experience, driver development experience and so on. For example, the requirements for senior embedded software development engineers are: having rich analysis and design capabilities of embedded reusable software systems, being able to independently complete project system solutions and solve system failures and problems; Proficient in C language application development, good programming habits and style, stable and reliable program; Good document writing skills and habits, able to write standard summary and detailed design documents; Familiar with project management process.

In the future, with the continuous acceleration of "triple play", 3G networks will be fully rolled out, which will bring greater demand for talents. For a long time to come, embedded software talents will be the target for enterprises to compete for.

Compared with the rapid development of embedded technology, the technology and training of educational institutions in China are relatively backward. On the one hand, some computer majors face unemployment after graduation; On the other hand, some embedded enterprises have projects that nobody does. The main reason for this phenomenon is that higher computer education in some universities is relatively out of touch with industrial development; At present, domestic higher education is either biased towards hardware or software. The style of hardware designers is usually relatively lacking in systematic and comprehensive design, while software developers are relatively lacking in hardware concepts. The embedded software talents that enterprises really need with hands-on ability need to be trained for a period of time before they can take up their posts.

At present, the development trend of the industry is that the system of more and more intelligent devices tends to be complex, and software will play a key role. At present, the industry is very short of talents with both software and hardware technology. According to the statistics of authoritative departments, the talent gap of embedded software in China is about 200,000 people every year.

Some time ago, some media reported that an electronics company in Guangzhou offered an annual salary of 300,000 yuan, but could not recruit suitable embedded engineers.

Does embedded technology have a big relationship with employment? Actually, it depends on your major and the scope of your future work.

If I study this major, I think it has something to do with employment. After all, it is a science. At present, the air conditioners on the market are basically developed in the embedded field. As far as the company I work for is concerned, wall-mounted air conditioners have gradually withdrawn from the stage. Of course, embedded technology is not only used in air conditioning, but also has a good development in other fields. ...

Which is better, digital embedded technology or embedded technology and application? You have to read the contents of these two courses, and the names are similar. I guess digital embedded technology is mainly used in consumer electronics, while embedded technology and application focus on industrial control occasions. The former focuses on the design of software, while the latter focuses on the combination of hardware and software.

Is the course of embedded technology and application difficult? Mainly using C, C++, JAVA, hardware knowledge and assembly involves some, the key is the operating system.

The requirement of mathematics lies in the algorithm part, and good logical thinking is enough. The related course is data structure.

It's best to read the English technical manual fluently in English, or use a dictionary or something, and slow down.

Embedded technology and application Most embedded systems are customized by users for specific tasks, but they are generally composed of the following modules: a computer or microcontroller, the word length may be pitifully 4 or 8 bits, 16 bits, 32 bits or even 64 bits. ROM (Non-volatile Read Only Memory) for storing firmware. RAM (Volatile Random Access Memory) is used to store program data.

This can be learned at Maker College.

Embedded: It is a special computer system as a device or a part of a device. Usually, an embedded system is an embedded processor control board, and its control program is stored in ROM. In fact, all devices with digital interfaces, such as watches, microwave ovens, video recorders, cars, etc. , using embedded systems, some embedded systems also include operating systems, but most embedded systems realize the whole control logic by a single program.

For example, an embedded system is a small system. You can compare it with your computer. Embedded system can be simply divided into hardware and software. Hardware is equivalent to a computer's hard disk, monitor, mouse, etc. The software is equivalent to the XP system of the computer.

You can learn without a strong foundation. For a beginner, I suggest you start with software, because this only needs a computer.

First, learn C language programming under linux (there are a lot of information about linux), and then learn some hardware-related knowledge. Finally, you can find a development board to transplant linux system.

Embedded technology application

Main employment direction and prospect: Embedded technology and its application are the new development of computer application technology, with wide application fields, broad development prospects and promising employment situation. Graduates of this major are suitable for computer application design and development in IT industry, information appliances and electromechanical products, as design and development engineers of embedded products and application systems, and engaged in design and development of embedded technology application projects, product maintenance and technical services.

Main courses and practical links: computer system composition, computer interface technology, microcontroller and application, database application, computer network and application, IT electronic product design and simulation (EDA), C/C++/JAVA programming, driver design, embedded system design, robot and intelligent electronic product software development, national (or industry) professional technical qualification certification course, IT electronic product design and simulation, and driver.

Search on the recruitment website, there are still many requirements for undergraduate courses, and the schools that offer this course in junior colleges don't know.

Whether the specialty of embedded technology and application is good or not, you must have a C language foundation before learning embedded Linux. It doesn't matter whether there is an assembly basis or not (just a few assembly instructions can be used at a glance). To what extent should C language be learned? Of course, the more familiar, the better. If you are not familiar with it, you should also have basic skills. For example, write an array to sort, sum the input numbers and so on. The only way to learn C language is to write more programs and practice more. It doesn't matter if there is a compilation error, you can solve it yourself. It doesn't matter if the execution is wrong, analyze it yourself. I used to practice C language with VC, and often tried to write some C language contest topics. They are all pure C, pure mathematics and pure logic topics, and do not involve interfaces. The embedded video of Maker College is very suitable for improving your programming ability.
