Quality attributes(Non operational) of embedded systems
- 2. Contents • Introduction • Quality Attributes of Embedded Systems Operational Attributes Non-operational Attributes
- 3. Quality Attributes: Non Operational 1. Testability and Debug- ability 2. Evolvability 3. Portability 4. Time to prototype and market 5. Per unit and total cost
- 4. Testability and Debug-ability Testing • How easily one can test design and by which mean can test it. 1. Hardware testing 2. Firmware testing Debugging ability • Fguring out the probable sources that create unexpected behavior in the total system.
- 5. Evolvability • Ease with which the embedded product can be modified to take advantage of new firmware or hardware technology.
- 6. Portability • “System Independence” • Is it capable of performing its operation as it is intended to do in various environments irrespective of different processor and or controller and embedded operating systems.
- 7. Time to prototype and market Time to market: Conceptualization Ready for selling or use. of a product Prototyping: Informal kind of rapid product development in which important feature of the under consider are develop. • Reduces time to market. • To shorten the time to prototype: -Reuse Time period elapsed
- 8. Per unit and total cost • Cost is an important factor which needs to be carefully monitored. • Monitoring cost right from the initial period to the maturing phase then till the termination is essential
- 9. Conclusion • While designing any embedded system the quality attributes play an important role.
