Q
Typical characteristics of embedded RT systems
A
- Predictable timing must be ensured, also in the worst-case scenario
- physically embedded in a product, clouse coupling between SW and HW, and typically scarce(knappe) HW resources
2
Q
The V-Model
A
Using the V-Model for real-time systems ensures a systematic approach to development, with thorough verification and validation at each stage
