Embedded Operating System
Embedded systems have the following characteristics:
Require small code size and can operate within limited storage space.
Application-oriented, can be cut and ported.
Used in specific fields, can support multitasking.
High reliability, timely response, can operate independently without human intervention.
High real-time performance, and requires solid-state storage.
Requires determinism and predictability before the system is put into operation.
Generally tested in multiple-choice questions.
BIT (Built-In Test) can complete fault detection and localization. It includes the following four types:
Power-On BIT: Self-test of all hardware resources when
