1. What is an embedded system?
An embedded system is a computer system specially designed to accomplish specific tasks, which is embedded in other devices to achieve specific functions or control operations. Embedded systems are usually characterized by small size, high efficiency and low energy consumption, and can operate under resource-constrained and complex environment conditions.
The core of an embedded system is a microprocessor (or microcontroller) chip, which includes a central processing unit (CPU), memory (such as flash memory and RAM), input and output interfaces (such as serial port, parallel port, USB, etc.) and various An interface for communicating with other devices (such as sensors, actuators, etc.). In addition to hardware components, embedded systems also require application-related software to perform specific tasks.
Embedded systems are widely used in various fields, such as the automotive industry, home appliances, medical equipment, industrial control, Internet of Things, etc. They have achieved the goals of automation, intelligence and efficiency in these fields.
The design and development process of an embedded system generally includes the following key steps:
1. Determine requirements: clarify the functional and performance requirements of the system, including hardware and software.
2. System design: Design the hardware architecture and software architecture of the system, including selecting the appropriate processor and other hardware components, and designing the software architecture and communication interface.
3. Develop software: Write and test embedded software, including drivers, operating systems, applications, etc. Software development may require the use of specific development tools and programming languages.
4. Hardware design: According to system requirements, design and manufacture hardware prototypes, including circuit design, PCB layout and manufacturing.
5. Integration and testing: Integrate software and hardware components together for overall system testing and validation.
6. Deployment and maintenance: Deploy the embedded system to the target device, and perform subsequent system maintenance and support.
Embedded systems have many advantages, including small footprint, low power consumption, fast response time, and high reliability.
