BE1-R3: EMBEDDED SYSTEMS
NOTE:
Time: three Hours Total Marks: 100
1.
a) What is embedded system design process? State its importance.
b) provided a option to choose Risc or Cisc micro controller, which 1 is preferred for
embedded applications and why?
c) We are provided tasks T1 and T2. What does it mean to say that they execute concurrently?
d) give a user level example of static and dynamic power management?
e) State Moore’s legal regulations. Comment on his latest prediction and state whether this legal regulations is
applicable in the case of designing embedded systems.
f) discuss how Port-based I/O is various from Bus-based I/O.
g) discuss the difference ranging from Black-box and White-box testing.
(7x4)
2.
a) elaborate the various optimizing design metrics involved in designing an embedded
system? How are they competing with 1 another?
b) Write a short note on Application-Specific Processors.
(12+6)
3.
a) Characterize embedded computing applications in terms of (i) providing sophisticated
functionality, (ii) performing to meet deadlines, and (iii) costs.
b) What is security modeling? State the objectives of security modeling.
c) elaborate the necessary conditions for deadlock to occur in a system?
(9+5+4)
4.
a) define the need for security in Bluetooth system. How Bluetooth wireless protocol is
differentiated from IrDA?
b) “Concurrent programming is stated to be harder than sequential programming.” Do you agree
with the statement? If yes, why? If no, how?
(12+6)
5.
a) elaborate the benefits of using a general-purpose processor in the case of designing an
embedded system? In this context, define the benefits of using a standard single-purpose
processor instead of using a general-purpose one.
b) Differentiate registers from memory. Compare Princeton architecture and Harvard
architecture. How is Cache memory related to embedded computing system?

2. Parts of the identical ques. should be answered together and in the identical
sequence.
6.
a) discuss why in Mobile IP we have triangular routing. What is the main issue with route
optimization?
