Embedded

Embedded systems are application-centric, dedicated computing systems built on modern computer technology, and meet specific functional requirements (such as real-time, reliability, low cost, low power consumption, etc.) through software and hardware collaborative design.

 

1. What are the Core Features of Embedded System?

‌Specialization‌: Customized for specific devices or scenarios (such as automotive control units, and smart home devices), highly integrated with software and hardware, and cannot be expanded to a general computing platform.

‌Embeddability‌: Integrated as a subsystem into larger mechanical or electrical equipment to achieve control, monitoring, or auxiliary operation functions.

 

2. What are the ‌Core Components of Embedded System?‌

Embedded systems consist of two parts: hardware and software:

 

1) ‌Hardware‌:

‌Processor‌: Microcontroller (MCU) or microprocessor (MPU) as the core.

‌Memory‌: ROM, RAM, and emerging embedded storage technologies (such as MRAM, ReRAM, PCM), with high durability and low power consumption; traditionally, small-capacity media such as E-PROM and EEPROM are used.

‌I/O Interface‌: Connect peripheral devices such as sensors and displays.

 

2) ‌Software‌:

Lightweight operating system or firmware, with API programming interface as the core of development, and low resource consumption.

 

3. What are the ‌Key Features of Embedded System?‌

‌Real-time‌: Most tasks need to be responded to under strict time constraints (such as industrial control).

‌Resource Constraints‌: Limited processor performance, storage space, and energy consumption budget.

‌High Reliability‌: Adapt to scenarios with zero tolerance for failures such as industry and medical care.

 

4. What is an Embedded System Used for?‌

Embedded systems have penetrated into many industries:

Automotive Electronics‌: Engine control, ADAS system.

‌Industrial Automation‌: PLC controller, robot.

‌Internet of Things and Edge Computing‌: Smart sensors, gateway devices and edge AI reasoning.

‌Consumer Electronics‌: Smart home, wearable devices.

 

5. ‌Technology Trends of Embedded System‌

‌Embedding of Emerging Storage Technologies‌: MRAM, ReRAM, etc. are accelerated to be integrated into embedded systems due to their high speed and low power consumption characteristics, helping edge AI and other scenarios.

‌Heterogeneous Computing Fusion‌: FPGA is combined with embedded processors to improve real-time processing capabilities (such as high-frequency signal analysis).

 

As the “invisible brain” of intelligent devices, embedded systems continue to promote innovations in the fields of the Internet of Things, Industry 4.0, and artificial intelligence. Its specialized design and non-universal architecture (different from the von Neumann system) make it an indispensable underlying support for modern electronic devices.
