What exactly is embedded technology?

What is embedded?

Ten years ago, maybe 70% of people didn’t understand it. But from today's perspective, whether it is in terms of industry applications, the explosion of smart hardware, the advent of the Internet of Things era, big data and other embedded technologies have achieved unprecedented development. So if you don't understand what embedded is, you are indeed a little out of it. To put it simply, embedded technology is application-centered, based on computer technology, and the software and hardware can be tailored. It is suitable for special computer system technology where application systems have strict requirements on function, reliability, cost, volume, and power consumption. . To give a simple example, your smartphone is actually an embedded system. Its system is configured with some hardware such as storage, CPU, and battery. However, considering power consumption, a system is specially customized for the smartphone. Just imagine, if a smartphone still uses the CPU of a desktop computer, the final product will weigh dozens of kilograms. Will anyone still buy such a mobile phone? Therefore, embedded systems are systems customized for product needs.

It originally originated from single-chip microcomputer technology and is the core of various digital electronic and electromechanical products. It is mainly used to realize functions such as control, monitoring or management of hardware equipment. Entering the 21st century, about 90% of computer application development in all walks of life will involve embedded development. The annual growth rate of the global embedded software market exceeds 12.5%. The annual industrial 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 more than 40%.

There are actually high and low levels of software development, and there are so many development languages! Such as C, C, and then to the popular Java, etc., which one should I learn? Why do some developers have very low wages, while some developers have a monthly salary of tens of thousands? And why is the salary of a senior Java programmer with 3 years of experience only 15K? And a low-level embedded engineer with two years of experience dares to ask for a salary of 15K-20k? It is precisely because of the good prospects. What is embedded? I think everyone has some understanding here.

But if you want to engage in embedded development, you must know a lot of technologies. It is not a pie-in-the-sky industry. A mature embedded engineer basically needs to understand application development and underlying development. Of course There will be many more included here.

When learning embedded development training, it generally emphasizes hardware platforms and practical projects. Learning is not just about learning a few technologies, but building your body of knowledge. For example, to learn embedded development, you need to start from basic Linux, C language, data structure, to ARM, assembly, Linux kernel, driver, etc. More importantly, through more project exercises, design at least 3 projects, as many as 10,000 Writing forced core code allows you to truly gain knowledge.
