No matter which direction the computer is in, you don't have to worry about money if you master it! !
The following is my personal opinion, I hope you can adopt it. Thank you. If you have any questions, please write privately.
Embedded system is undoubtedly one of the hottest and most promising IT application fields. Embedded systems are used in some applications.
Hardware resources (such as processor, memory, etc.). ) is usually very limited and
Moreover, it is very sensitive to cost and sometimes requires high real-time response. Especially with the intelligent and embedded consumer appliances.
Type is more important. Like the mobile phone, PDA, electronic dictionary, videophone, VCD/DVD/MP3 we usually see.
Player, digital camera (DC), digital video camera (DV), USB flash drive, set-top box, high definition.
Television (HDTV), game machines, intelligent toys, switches, routers, numerical control equipment or instruments, automotive electronics, household appliances.
Medical electrical control system
Instruments, aerospace equipment and so on are typical embedded systems. Embedded will be the foundation of our digital existence.
Basically, a PC has actually embedded 10 microcontrollers, and a high-end car needs about 60 or 70 microcontrollers.
Machine; Embedded processors are everywhere, and the global annual output exceeds 654.38+000 billion. How amazing is this?
Numbers!
In addition, people who can write drivers are very scarce at present (drivers can also belong to the embedded category), including
DDK development environment and WDM driver in desktop Windows. The company always introduces new products, every new product.
When the product comes out, it needs a write driver to be used by the operating system. To write a driver, you must master it.
The internal working principle of operating system (such as Windows or Linux) also involves a small amount of hardware knowledge, which is difficult.
So people in this field are hard to find. Students who want to be masters can also make a breakthrough in driving. but
According to friends in this field, after doing it, you will find that it is not that difficult. In fact, drivers and workers
Making a version is very comfortable, and it will be empty for a while, only when the company introduces a new chip or a new OS.
Now we need to develop a new version of the driver.
