Embed, meaning to put a small thing is stuffed to where;

Embedded computers, refers to the smaller, eliminated, cheap, simple point of the computer, installed in need of computer control where to go; in modern times there are many electronic devices need to do intelligent control, which equipment to control?

Toys, home appliances, air conditioners, refrigerators, mice, wireless routers, car engines, MP3 players, digital cameras, printers, cameras, hard drives, projectors, punch cards, credit card machines, electronic watches, etc... Almost all aspects of our lives, and factory production, as long as the equipment is charged, almost all require computer control.

But you can not use i3/i5/i7 such a high-end CPU to control, a convenient price, on the other hand also overqualified, with this need not; those who eliminated, as long as a few yuan a piece of 8051, this kind of CPU is just good, if the function is stronger, you can use arm; of course, 20~ After 30 years, it is possible for us to take the current i7 to do embedded, because at that time must have been eliminated;

Most of the CPU used to be embedded is the core of the previous elimination, but sometimes for low-power performance and ease of use, but also with the new concept of modern design, especially for the SOC architecture for ease of use, AVR like enhanced 8051.

Today, the equipment around us not only to embed the CPU to make it intelligent, but also to synchronize and coordinate, if all the charged objects are networked and intelligently coordinated control, it is the internet of things; what can the internet of things do?

Unconsciously around a lot of things have evolved to the internet of things, car GPS software will be real-time networking to obtain traffic congestion, immediately make navigation changes, avoid congestion; when the car is over-speed toll station, the wireless signal is connected to a credit card in the car, and then the Internet realizes automatic deduction; Water is already connected to the machine, there is no need for manual door-reading, to the time the bill automatically can be sent into text messages, and automatic bank card deduction fee, Network Camera has been networked, so that you can use the phone in any place to see the baby's situation; the air-conditioning is also starting to connect to the remote control before you get home. We are entering the age of the Internet of things.
