0.1.2. Why learn embedded
What is Embedded
Traditional definition ( 狭义嵌入式): Embedded system is application-centric , computer technology, and software and hardware can be tailored for application system functionality, reliability, cost, size, power consumption has strict requirements dedicated computer system.
The current objective definition ( 泛嵌入式): All computer systems other than a PC can be called embedded systems. Typical: smart phones, industrial robots, automotive electronics, aerospace (four-axis aircraft), security monitoring (IPC) and so on.
Technical characteristics of embedded systems
- Low power consumption (BLE, zigbee, low power consumption Wifi)
- Networking technology (4G, BT, zigbee, wifi)
- RISC CPU（ARM、MIPS）
- OS（linux、Android、RTOS）
- Layered (bottom layer, the OS layer and application layer)
- Span, miscellaneous knowledge, the learning curve is steep and lingering
Three wave of information technology
Embedded in the direction of mainstream hot
- Consumer electronics (smartphones, game consoles, wearable)
- Industrial Automation (Industrial robot)
- Automotive (vehicle control systems, vehicle navigation, in-car entertainment, autopilot system)
- Aerospace (four-axis aircraft, manned aircraft)
- Things (the wisdom of agriculture, intelligent transportation, smart home ??????)
