Since the embedded system adopts a microprocessor to implement a relatively single function and a separate operating system, a large number of peripheral devices are often not required. Therefore, in terms of volume and power consumption, embedded system has its own advantages.

Characteristics:

1. Small system kernel;

2. Strong specificity;

3. System streamlining;

4. High real-time system software (OS) is the basic requirement of embedded software;

5. For embedded software development to be standardized, a multitasking operating system must be used.

6. Embedded system development requires development tools and environments.
