Embedded system architecture, definition of embedded system

1. Embedded system is simply a special computer system designed for specific applications.

2. The embedded system is different from the ordinary PC or notebook, and the external characteristics of the embedded system such as the external size, power consumption, macro guessing, and external adapter must meet the requirements and limitations of the application.

3. The software of the embedded system, including the operating system, is burned on a circuit board.

4. It uses a low-power x86 CPU, adopts a modular design, and is equipped with the most basic computer peripherals. This type of computer usually uses the Windows operating system.

5. The CPU of the embedded system can be: 4-bit, 8-bit, 16-bit, 32-bit.

6. Embedded systems are widely used.

7. The architecture of the embedded system.

8. The embedded system is more characterized by SoC, that is, the entire system is integrated on a chip, for example, ATMEL's ARM7 chip 91SAM7X128 256, etc.; Users can get an inexpensive yet powerful embedded system.

The embedded field is a relatively new space, and many technologies have not been around for a long time, and most people do not have the conditions to contact or enter the industry, and need to receive special training and professional guidance to understand the specific development process. Therefore, in order to enter the field of embedded system development, it is necessary to attend courses from some professional training institutions and look for opportunities to practice projects and increase project experience, only in this way can the gap between companies and job seekers be bridged.

Among the many mask training institutions, the Maker Academy took the lead in launching the embedded software engineer training project, and integrated the employment needs and plans of many enterprises, employment-oriented, skill-oriented, with the domestic top training environment and enterprise atmosphere norms, to improve the professional quality of students, starting from real cases, the introduction of internationally renowned manufacturers, institutions training products, and constantly develop training programs to meet the needs of enterprise talents, for the Chinese IT industry to train and deliver embedded software engineers, and other practical and comprehensive talents urgently needed in the IT industry.

Embedded frames are similar to framed web pages, except that the embedded frame and its content are embedded in an existing web page. Anything that can be put into a normal modified web page can be placed in an embedded frame. You can customize the embedded frame just like you would a normal frame, and you can also enable scrollbars in this frame.

One of the benefits of using an embedded frame instead of a frame is that you don't need to create a separate framed web page when making embedded content. Embedded frames have many uses:

Contracts can be inserted for ** visitors to fill out. You can give examples of what other web pages look like. Can be used as a form container.

It can be used as a scrolling box to display products and *** nuclear ruler ruined.

Definition: Embedded system is an application-centric, computer technology-based, software and hardware can be tailored, suitable for the application system has special requirements for function, reliability, cost, volume, power consumption and other aspects of the special computer system.

Features: (1) Embedded systems are application-oriented. The CPU in the embedded system is specially designed for specific applications, with the characteristics of low power consumption, small size, high integration, etc., which can integrate many of the tasks completed by the board in the general-purpose CPU into the chip, which is conducive to the miniaturization of the whole system design.

2) Embedded systems involve various industries such as advanced computer technology, semiconductor technology, electronic technology, communication and software. It is a technology-intensive, capital-intensive, highly dispersed, and innovative knowledge integration system.

3) The hardware and software of embedded systems must be highly customizable.

4) The life cycle of an embedded system is quite long. The embedded megavertical system is organically combined with the specific application, and its upgrading is also carried out simultaneously with the specific product.

5) The embedded system itself does not have the ability to further develop on it. After the design is completed, if the user needs to modify the program functions, it must use a set of special development tools and environments.

6) In order to improve the execution speed and system reliability, the software in the embedded system is generally solidified in the memory chip or microcontroller, rather than stored in the disk and other carriers. If you want to know more about embedded, you can just go and see Zhu Youpeng's free**, everything about embedded has been talked about.

<> embedded system is application-centric, based on computer technology, and software and hardware can be tailored, which is suitable for the application system to have strict requirements for function, reliability, cost, volume, and power consumption.

Embedded systems originate from semiconductor integrated circuits which are divided into transistors and integrated circuits. In the 70s of the 20th century, integrated circuits gave rise to microprocessors Microprocessors are intelligent cores. It has two functions, one is the computing and processing function, that is, the high-speed and massive calculation ability, which has promoted the rapid development of computer independence; The second is the control function, the embedded system belongs to the control function, and the control function produces a microcontroller, commonly known as a single-chip microcomputer, which promotes the independent development of the embedded system so far.
