? ? ? ? ?
1. (a) discuss the terms computer architecture, computer organization and com-
puter design in a detailed fashion. [8]
(b) discuss about MIPS, FLOPS rating of a processor. How do we arrive at these
values. [8]
2. (a) Design a circuit transferring data from a 4bit register which uses D flip-flops
to a different register which employs RS flip-flops. [8]
(b) elaborate register transfer logic languages? discuss few RTL statement for
branching with their true functioning. [8]
3. (a) provide the typical horizontal and vertical microinstruction formats. [8]
(b) define how microinstructions are organizes in control memory and how they
are interpreted. [8]
4. (a) How many bits are needed to store the outcome addition, subtraction, multipli-
cation and division of 2 n-bit unsigned numbers. Prove. [8]
(b) What is overflow and underflow? What is the reason? If the computer is
considered as infinite system do we still have these issues. [8]
5. (a) What is a virtual memory technique? discuss various virtual memory tech-
niques. [8]
(b) discuss how the technique of paging can be implemented [8]
6. discuss the following:
(a) CPU - I O P Communication
(b) I O P
(c) IBM 370 I/O Channel. [5+5+6]
7. discuss 3 segment instruction pipeline. Show the timing diagram and show the
timing diagram with data conflict. [16]
8. elaborate the various types of Multi stage Switching networks? discuss with neat
sketch. Compare their functioning. [16]

1. (a) discuss about sign magnitude and 2’s complement approaches for representing
the fixed point numbers. Why 2’s complement is preferable.
(b) provide means to identify whether or not an overflow has occurred in 2s comple-
ment addition or subtraction operations. Take 1 example for every possible
situation and discuss. presume four bit registers.
(c) Distinguish ranging from tightly coupled microprocessors and tightly coupled Mi-
