What is the application technology test for embedded system designers?

1. Embedded system designer belongs to the intermediate qualification examination of the soft examination. The embedded system designer of the soft examination includes two examination subjects: basic knowledge and applied technology. The embedded system designer exam requires all subjects to be passed in one exam.The soft examination of embedded system designer includes two examination subjects: basic knowledge and applied technology.

2. There are three subjects in total: comprehensive knowledge, case analysis and thesis. There are two subjects for embedded system designers. Embedded system designers belong to the soft examination. The elementary and intermediate soft examinations include two examination subjects: basic knowledge and applied technology. The advanced soft examination includes three subjects: comprehensive knowledge, case analysis and thesis.

3. Examination question types for each subject of embedded system designer: (1) Basic knowledge of embedded system, examination time is 150 minutes, written examination, multiple-choice questions; (2) Embedded system application technology (case analysis), examination time is 150 minutes, written examination, questions and answers.

Application and development of embedded system

1. Download and use BUSYBOX software for function reduction, resulting in a most The basic root file system, and then add other programs according to the needs of your own application.

2. Embedded system development is the development of operating systems on all electronic devices except computers. The development targets include mobile phones, handheld computers, electromechanical systems, etc., which are generally composed of four parts, including embedded microprocessors, peripheral hardware equipment, embedded operating systems and user applications. Become.

3. At present, the embedded system has been used in national defense, national economy and socialIt will be widely applied in various fields of life, and it will be used in various places such as enterprises, armies, offices, laboratories and individual families. See the figure ● Military use.

What are the application scenarios of embedded systems?

1. At present, the embedded system has been widely applied in various fields of national defense, national economy and social life, and is used in various places such as enterprises, the army, offices, laboratories and individuals and families. Military use.

2. Information management, process control, auxiliary technology, translation, multimedia application, computer network and other fields. Information management is a computer technology based on database management system, which helps managers improve their decision-making level and business strategies. Information processing includes data collection, storage, processing, classification, sorting, retrieval and publication.

3. Home automation products, such as thermostats, air conditioners, sprinklers and safety monitoring systems. Household appliances, including microwave ovens, washing machines, TVs, DVD players and recorders.

What is the traditional design method of embedded system

In general, the system design process of software and hardware collaborative design can be divided into four stages: system description, system design, simulation verification and comprehensive implementation. The system description uses one or more system-level description languages to comprehensively describe the function and performance of the embedded system to be designed, and the process of establishing a software and hardware model of the system.

An embedded system is a specialized computer system designed as part of a larger system, not as an independent device.This means that embedded systems are usually designed to perform specific tasks instead of providing multiple functions.

Hardware/software collaborative design: based on the design results of the architecture, the hardware and software of the system are designed in detail. In general, most of the work of embedded system design focuses on software design. The methods often adopted by modern software engineering are object-oriented technology, software component technology and modular design.

Embedded development refers to development under an embedded operating system. Commonly used systems include WinCE, ucos, vxworks, linux, android, etc.

Development and application of embedded system

1. EmbeddedEntry system refers to a special computer system that is application-centered, based on computer technology, software and hardware can be tailored, and adapted to the strict requirements of the application system for function, reliability, volume and power consumption.

2. Introduction to embedded systems Embedded systems can abstract a typical component model, which can be divided into hardware layer, software layer and functional layer.

3. The development of embedded systems has roughly gone through the following three stages: the first stage: the early stage of embedded technology. The embedded system exists in the form of a programmable controller with simple special computers or single-chip microcomputers as the core, with monitoring, servo, equipment indication and other functions.

4. Embedded technology plays a key role in the development of artificial intelligence and edge computing. Edge computing uses embeddingEntry devices for data processing and analysis can bring computing power closer to the data source and reduce data transmission and delay.

5. Embedded system is a "special computer system completely embedded in the controlled device and designed for specific applications". To control, monitor or assist equipment, machines or equipment used in factory operation.

6. The development of embedded systems is divided into four stages: no operating system stage, simple operating system stage, real-time operating system stage, and Internet-oriented stage. The first stage without operating system is a programmable controller system with a single chip as the core, which has the functions of monitoring, servo and indication equipment.
