This article is about what kind of computers outnumber microcomputers. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Embedded computers surpass microcomputers in number; embedded technology is "dedicated" computer technology, and "dedicated" refers to a specific application, such as network, communication, etc.; from an academic point of view, embedded system is a special computer system centered on application and based on computer technology.

It is the embedded computer that exceeds the number of microcomputers.

Popularly speaking, embedded technology is "dedicated" computer technology, which refers to a specific application, such as network, communication, audio, video, industrial control, etc., from an academic point of view, embedded system is application-centric, based on computer technology, and hardware and software can be tailored. It is suitable for special computer systems that have strict requirements on function, reliability, cost, volume and power consumption. it is generally composed of embedded microprocessors, peripheral hardware devices, embedded operating systems and user applications.

To understand the concept of embedded system from three aspects.

1. From the hardware. The peripheral devices based on CPU are integrated into the CPU chip, such as the early computers based on X86 architecture. CPU only has the functions of calculator and accumulator, and all chips have to be extended by external bridges. Serial ports, such as serial ports, are realized by external 16C550/2 serial port controller chips, while the current serial port controller chips have long been integrated into CPU, and PCs have graphics cards. Most embedded processors have LCD controllers, but in a sense, they are equivalent to graphics cards. Compared with the high-end IXP network processor CPU under the ARM type Intel Xscale architecture, the PCI controller is integrated internally (it can be configured to support four PCI slave devices or CPI slave devices); it also integrates three NPE network processor engines, two of which correspond to two MAC addresses and can be used for gateway switching, while the other NPE network processor engine supports DSL, as long as an external PHY chip is added to achieve DSL Internet access function. The highest frequency of the IXP series can reach 1.8g, supporting 2G memory, 1G × 10 or 10G × 1 Ethernet port or Febre channel optical channel. The IXP series should be the highest processor integrated by intel into a Xscale core based on arm system architecture.

2. From the software point of view, the application is selected in the kernel of the custom operating system, and the kernel is downloaded to ROM after compilation. The application component selected when customizing the operating system kernel is to complete the "embedding" of the software, such as WinCE kernel customization, there will be corresponding choices, such as Wordpad,PDF,MediaPlay, and so on. If we choose, after CE starts, we can find these things in the interface. If it is the windows operating system of the former general PC, most of the things need to be reinstalled.

3. Burn the software kernel or application file system into the ROM of the embedded system hardware platform to realize a real "embedding".
