Where is embedded headed? What is the direction of development of embedded?

Embedded technology development prospects and development directions.

Embedded technology can be said to be one of the hottest and most promising IT application fields at present, embedded technology and application major follows the principle of industrial development and positioning talent training, cultivating students in the embedded field of software development, software and hardware testing, system maintenance and other skills, with the embedded technology application more and more widespread, embedded system technology has become a very broad application prospect at present, Next, let's take a brief look at the employment prospects and development direction of embedded technology.

Embedded Technology Prospects:

The wide application of embedded systems will inevitably bring a great demand for related technical talents, domestic embedded software field technical personnel are quite scarce, China's multinational companies and domestic home appliance giants are facing a serious shortage of embedded talents, according to relevant surveys show that China's embedded software industry has a huge gap of at least 500,000 talents every year, and this number is still growing at an annual rate of 20%, but the amount of domestic embedded software talents is really a drop in the bucket, Far from being able to meet the needs of the industry, there are two main reasons: 1growth in demand; 2.There is a huge shortage of talent with embedded software development skills.

After interpreting the above content, I would like to share with you the salary of embedded engineers, I believe this is also a problem that many people are concerned about, generally come to the institute, embedded talents can be said to be well-deserved white-collar workers, Huaqing Vision has trained the salary level of fresh college students can generally reach 1w+, several years of work experience of engineers will be higher, of course, people who understand embedded technology are also very suitable for entrepreneurship, so the embedded employment prospects are very wide.

Embedded Technology Exhibition Direction:

Embedded technology has a wide range of applications, mobile phones, electronic dictionaries, visual applications, digital cameras, automotive electronics and home appliance control systems, etc. are typical embedded systems in daily life, students can choose to engage in computer application design and development in household electronics, automotive electronics, telecommunications and other industries after graduation, and can choose to work as a design and development engineer of embedded products and application systems, engaged in the design and development of embedded technology application projects, product maintenance and technical services.

The above is the development prospect and development direction of embedded technology, I hope it will help you choose.

The development of embedded systems has gone through the following three stages:

The first stage: the early stage of embedding technology. The embedded system exists in the form of a programmable controller with simple functions as a special computer or a single-chip microcomputer as the core, with functions such as monitoring, servo, and equipment indication.

Most of this system is used in all kinds of industrial control and aircraft, missiles and other equipment.

Phase 2: Marked by high-end embedded CPUs and embedded operating systems. The main feature of this stage system is that the computer hardware has appeared with highly reliable and low-power embedded CPUs, such as ARM, PowerPC, etc., and supports the operating system to support the development and operation of complex applications.

The third stage: marked by chip technology and Internet technology. With the rapid development of microelectronics, SoC (System-on-Chip) has made embedded systems smaller and more powerful.

Most embedded systems are still isolated from the Internet, but with the development of the Internet and the increasingly close combination of Internet technology and information appliances and industrial control technology, embedded technology is entering a period of rapid development and wide application.

Many friends want to know what are the advantages of engaging in embedded development, so let's take a look.

What are the advantages of engaging in embedded development?There are two major advantages to working in embedded.

1. The work intensity is relatively low, and there is no need to repeat work;

2. It is a company engaged in embedded systems, and it has its own product plan, and it will act according to its own section and will not be modified all the time.

Embedded Development Career ProspectsThe prospect of embedded development is very broad, because the entry threshold of embedded development is relatively high, the required development talents are also relatively scarce, and the treatment is much higher than that of other industries, and if you want to become a senior embedded development engineer, you not only need experience in various language programming, system operation, drivers, etc., but also be able to independently complete the project system plan and solve system failures and problems.

Skills that an embedded development engineer needs to masterKnowledge of C, C++ and some simple programming;

Familiarity with at least one embedded systems software development environment;

Familiar with the development process and common principles of an embedded software system;

Able to read general embedded schematics.

How do embedded development engineers be treated

If you want to develop in the direction of embedded software, the most common one is the embedded Linux direction, and I think there are about 3 stages to pay attention to this direction:

1. Embedded Linux upper-layer applications, including GUI development for QT.

2. Embedded Linux system development.

3. Embedded Linux driver development.

At present, the embedded mainly faces several operating systems, such as Linux, Wince, VXWaws and so on.

Linux is open source and free, and its source** is open, which is more suitable for us to learn embedded.

So you can try the following routes:

1) C language is the strongest of all programming languages, single-chip microcomputer, DSP, and various chips similar to ARM can be programmed in C language), so it must be very proficient.

2) The principle of operating system is required, if you are a computer major graduate, it doesn't matter, if you are a non-computer major, you must find a relatively simple computer principle book to take a look, what is called "process", "thread", "system scheduling" and other basic problems to figure out.

3) (3) The Linux operating system is written in C language, so you should also learn Linux programming first, only if you can apply it, can you take a closer look at the essence of its kernel.

4) Understand the architecture, principle, and assembly instructions of ARM, we generally rarely write assembly in embedded development, but the minimum requirement is to be able to understand ARM assembly.

5) When transplanting the system, you need to start with the bottommost bootloader, then the kernel port, the file system port, etc. The dependence on the hardware of the porting part is very large, and the configuration steps are relatively complex, and there is not much detailed information.

6) Drive development.

Linux driver design is both a challenging area and a broad one.

The essence of Linux driver design belongs to the category of Linux kernel programming, so there are requirements for Linux kernel collapse and kernel programming. Before you study, you need to understand the composition of the Linux kernel, because each part needs to be studied in detail enough to expand into a thick book.

The above is just a general framework, and there will be many things involved in the actual development, such as: cross-compilation, makefile, shell script, etc., so the learning embedded cycle is longer, the threshold is higher, and self-learning requires strong learning ability and professional skills. As long as you can persevere, you will definitely succeed!
