Communication Engineering, Electronics & Instrumentation Engineering,
Electronics & Control Engineering and Electronics & Telematics)
Time: three hours Max Marks: 80
ans any 5 ques.
All ques. carry equal marks
? ? ? ? ?
1. (a) explain about Flynn’s classification of computers.
(b) discuss about communication topologies used in multiprocessors. [16]
2. Write about direct, indirect, register direct, register indirect, immediate, implicit,
relative, index, and base address mode of addressing. Why do we need so many
addressing modes? Is the instruction size influenced by the number of addressing
modes which a processor supports? State whether the number of addressing modes
will be more in Risc or Cisc? [16]
3. (a) Why do we need subroutine register in a control unit? discuss. [8]
(b) discuss nanoinstructions and nanometry. Why do we them? [8]
4. discuss the computational errors. Why do they occur?. provide a few issues where
these errors are catastrophic. Also, provide a few practical examples (algorithms) where
fault gets
(a) accumulated and
(b) multiplies. [16]
5. discuss the subsequent with applications for each:
(a) ROM
(b) PROM
(c) EPROM
(d) EEPROM. [4+4+4+4]
6. discuss the following:
(a) Isolated Vs Memory mapped I/O
(b) I/O Bus Vs Memory Bus
(c) I/O Interface
(d) Peripheral Devices. [4+4+4+4]
7. (a) What is pipelining? discuss. [8]
(b) discuss 4 segment pipelining. [8]
1 of 2
Code No: R05310201 Set No. 1
8. (a) discuss multiport memory organization with a neat sketch.
(b) discuss system bus structure for multiprocessors with a neat sketch. [8+8]

ments for a good programming language? [6]
