Question 1

Typical characteristics of embedded RT systems

Answer 1

• 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

Question 2

The V-Model

Answer 2

Using the V-Model for real-time systems ensures a systematic approach to development, with thorough verification and validation at each stage

Requirements Definition -> System Testing

System Design -> Integration Testing

Question 3

Requirements definition

Answer 3

Identify and document timing requirements

Question 4

System Design

Answer 4

Associate timing requirements to individual arch. elements

Question 5

Detailed Design

Answer 5

• Define timing properties.
• Timing analysis based on execution time estimates/budgets

Question 6

Implementation

Answer 6

Avoid upredictable and costly constructs
