1. (a) Discuss about Flynn’s classification of computers.
(b) Explain 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? Explain. [8]
(b) Explain nanoinstructions and nanometry. Why do we them? [8]
4. Explain the computational errors. Why do they occur?. Give some problems where
these errors are catastrophic. Also, give some practical examples (algorithms) where
error gets
(a) accumulated and
(b) multiplies. [16]
5. Explain the following with applications for each:
(a) ROM
(b) PROM
© EPROM
(d) EEPROM. [4+4+4+4]
6. Explain the following:
(a) Isolated Vs Memory mapped I/O
(b) I/O Bus Vs Memory Bus
© I/O Interface
(d) Peripheral Devices. [4+4+4+4]
7. (a) What is pipelining? Explain. [8]
(b) Explain four segment pipelining.
