GDB Problem Statment:

The complexity of Integrated Circuits (https://en.wikipedia.org/wiki/Integrated_circuit) is increasing exponentially with time which in turn make the number of available transistors to grow fast within a chip.

This increase in number of transistors in an IC is way more than the productive design need. The situation raised due this problem is a well-known design productivity gap.

IoT (https://en.wikipedia.org/wiki/Internet_of_things) and Mobile devices (https://en.wikipedia.org/wiki/Mobile_computing) will significantly decrease the above mentioned design productivity gap, do you agree or disagree? Give your opinion with strong arguments.

any idea ?

plz share your gdb here


it’s difficult to keep both the things parallel ‘productive design’ and the ‘performance’. Productive design is the public need and Performance is the devices’ need.

Let me make it more simple to make you all understand,

The teacher asked you to compare the productive design, its need in todays world. Like your mobile devices are productive and contain a lot of functions. But with the passage of time it would be difficult to introduce more device specs. it means Now your mobile phones have 4gb Ram, 64gb Rom. But for more specs the device size will have to be more...

Your teacher is asking you to comment on this complex situation. because if you will introduce more components the device size will increase.

i hope you will all understand this :) if you still feel any problem, reply here. Try to do by yourself.

1. difference between sequential digital circuit and combinational digital circuit.

2. 2 bit down count having states A, B, C, D counter counts up if X = 1, and down when x = 0, write if then statement

3. Applications of ROM

4. What are the 6 char of flip flop.

5. draw next state table of a 3 bit up counter using SR flip flop.


6. State diagram di v the table of input and output banana tha.

7. Memory chips can be connected together in diff manners to increase the size, draw block diagram of 4 Kword from 4K x bytes.

8. Errors in Analog to digital

9.how many bytes inn 32K 8 memory 10Why some counters are called pre set?

1 = 3 charactertics of serial in/ serial out 4 bit right shift 2 = what is operational amplifier and how it can be used? 3 = what is meant by monotonicity of digital to analogue converter? 4 = difference between truth table and next state table? 5 = flip flop charactertics 6 = how many states in 8 bit jhonsn counter sequence? 7 = Applictions of Rom 8 = why is master slave flip flops called trissersed flip flop? 9 = jhosn and ring counter difference 10 = reduction process 11= binery – weighted- input digital to analoug converter. 12 = make diagrm of next state table


I agree, IoT and Mobile devices are going to decrease the currently existing productivity gap between the design needs and exponentially increasing number of transistors per IC. The demand of IoT and Portable devices is increasing, there is an estimate by experts that by the year 2020, IoT will consist of 30 billion objects. So the demand is very high, for smaller, embedded and portable devices for Internet as well as computation.
We are already seeing the productivity gap getting smaller and smaller as more and more smart and portable devices coming in the market. Although according to Moore's law, the number of transistors per IC would double every 18 months, but the number of smarter, portable and computing devices being invented every 18 month is already increasing, so the gap is definitely being filled by IoT and Mobile devices.
