Answer ONE Question from each Unit
All Questions Carry Equal Marks
All parts of the question must be answered in one place only
UNIT I
1. Explain Amdahl's law in detail with suitable applications.
Explain different addressing modes for instruction set architecture with an example for each.

2. Mention different types of control flow instructions, and explain the supporting addressing modes
elaborating the parameters of evaluation.
Explain type and size of operands explaining their operation in the instruction set.
UNIT II
3. Explain hardware based speculation and limitations of instruction level parallelism.
Explain Tomasulo's algorithm with an example and give one real time application to it.
4. Explain cross cutting issue of hardware versus software speculation.
What is instruction level parallelism? Elaborate instruction level parallelism concepts and challenges.

UNIT III
5. Which is more important for floating point programs: two-way set associativity or hit under
one miss? Assume the following average miss rates for 8kB data cahes: 11.4% for floating-point
programs with a direct-mapped cache, 10.7% for these programs with a two-way set-associative
cache, 7.4% for integer programs with a direct-mapped cache and 6.0% for integer programs with
a two-way set-associative cache. Assume the average memory stall time is just the product of
the miss rate and the miss penalty and the cache describe for 16 clock cycles of L2 cache.
Explain how a protection is achieved via virtual memory.
6. Explain about multi-threading concept with suitable examples.
What are the limitations in symmetric shared memory multiprocessors and snooping protocols?

Explain characteristics of transaction processing council benchmarks.
8. Discuss about I/O performance, reliability measures and bench marks.
Enumerate the steps to follow in designing an I/O system. Explain in detail.
UNIT V
9. Explain interconnecting network's practical problems in detail with an example.
Write a note on designing procedure of a cluster with an example.
10. Interpret the interconnection network media. How it will affect the interconnection networking
media.

challenges.
