Q) Write the Challenges faced in designing an Embedded System?
Answers
● Flexibility and Upgradeability
● Reliability
● Optimizing Power Dissipation & Power Consumption
● Process Deadlines
● Amount & Type of Hardware Needed
Step-By-Step Explanations
Flexibility and Upgradeability:
It means that the changes or upgrading product for next generation uses, can be added
extra features in an upgrade version of the previous one. Several distinct changes of
upgradability of product by using the same platform.
Reliability
It is the customer expectation of smooth working of the product they purchase, reliability of
the product is done by testing, verification, and validation of the product.
Optimizing Power Dissipation & Power Consumption
It is the most important step, power consumption and saving by clock reduction and voltage
reduction method. Saving power during program execution is done by wait and stop
instruction.
Process Deadlines
It will be difficult to meet all system deadlines while minimizing the memory usage, power
consumption, cost, and processor clock rate.
Amount & Type of Hardware Needed
To meet the expertise, like less manufacturing cost and get the best performance the
selection of hardware is an important thing. Optimization of hardware, the microprocessor is
needed to be selected as the availability of peripheral devices, and memory to be specific.
Failure to meet the requirement like adding too much hardware causes excessive cost.
