What is the traditional design method of embedded system?

The traditional design method of embedded system is as follows:

1, embedded system generally refers to non-PC system, which has computer function but is not called computer equipment or equipment.

2. It is a special computer system which is application-centered, flexible in software and hardware, and meets the comprehensive and strict requirements of the application system on function, reliability, cost, volume and power consumption.

3. Simply put, the embedded system integrates the application software and hardware of the system, which is similar to the working mode of BIOS in PC. It has the characteristics of small software code, high degree of automation and fast response, and is especially suitable for systems that require real-time and multi-task.

4. Embedded system is mainly composed of embedded processor, related supporting hardware, embedded operating system and application software system. It is a device that can work independently.

5. Embedded system includes almost all electrical equipment in life, such as PDA, mobile computing equipment, TV set-top box, mobile Internet access, digital TV, multimedia, automobiles, microwave ovens, digital cameras, home automation systems, elevators, air conditioners, security systems, vending machines, mobile phones, consumer electronics, industrial automation instruments and medical instruments.

6. Hardware part of embedded system, including processor/microprocessor, memory and peripherals, I/O port, graphics controller, etc.

7. Embedded system is different from general computer processing system. It has no large storage medium like hard disk, and most of them use EPROM, EEPROM or FlashMemory as storage medium.

8. Software includes operating system software (requiring real-time multi-task operation) and application program design.

9. The application program controls the operation and behavior of the system; The operating system controls the interaction between applications and hardware.

Brief introduction of embedded system

Embedded system consists of hardware and software. It is a device that can run independently. Its software content only includes software operating environment and its operating system. Hardware content includes signal processor, memory, communication module, etc.

Compared with general computer processing systems, embedded systems are quite different. It can't realize mass storage function because there is no matching mass media. Most of the storage media used are E-PROM, EEPROM, etc. The software part takes API programming interface as the core of the development platform.
