2. • Systematic approach to creating a design.
2 basic Principles used in design methodology:
 Problem Partitioning: Large System cannot handle
as a whole. So dividing the system into smaller
systems.
 Abstraction: overall behavior of the system.

3. Partitioning
• When partitioning is used “ The design activity
focuses on one part of the system at the time”
• Also the one sub system can interact with other
systems by clear understanding. For this purpose we
need “Abstraction” concept.

4. The R-T System Design Process
• Allocate system functions to concurrent processes.
• Design algorithms for stimulus processing.
• Design a scheduling system.

5. Ex: Microwave oven
This is one of the Real Time System which involves great
care in Design and Implementation.
