ans any 5 ques.
All ques. carry equal marks

1.a) provide the reasons why cache coherence is an accepted requirement in small scale multiprocessors?
b) Draw the state transition diagram for an individual cache block in a directory based system.[8+8]

2. elaborate the challenges of multiple-issue processors? discuss. [16]

3. elaborate the 2 factor that speedup depends on. Discuss? [16]

4. elaborate the 3 ideas that hardware speculation make use of? discuss. [16]

5. explain in detail conditional branch operations? provide examples for each? [16]

6. (a) describe the performance parameters of the interconnection networks.
(b) presume a network with a bandwidth of 1000M bits/sec has a sending overhead of 80microsec and receiving overhead of 100microsec.Assume 2 machines 1 wants to send a 10,000byte message to the other [including header] and a message format allows 10,000bytes in a single message. compute the total latency to send a message from 1 machine to a different in a SAN. Assuming they are 10m apart. [8+8]

7. explain in detail about the RAID levels. [16]

8. discuss the techniques in increasing memory bandwidth. [16].
