What is Flynn’s classification? What do you mean by Cache coherence? What do you mean by Address space? Whether for single instruction execution non-pipeline system is better than pipeline system? Justify. What do you mean by Distributed memory system? How many Floating point registers are there in the Floating Point Unit of SPARC? How overlapped CPU and I/O operations are performed in computer system? Explain with example. State Amdahl’s low and explain. To multiply 18 by -1, if 18 is in source, how many cycles needed by ARM? (2 x 10) Assume a cache miss penalty is 100 clock cycles, and all instructions take 1.0 clock cycles. Let the average miss rate is 2%, there is an average of 1.5 memory references per instructions, and the average number of cache misses per 1000 instructions is 30. What is the impact on the performance and calculate the impact using both misses per instruction and miss rate? What are the writing policies of Cache? Explain with diagram. (10) What do you mean by Speed-Up of pipeline? Derive equations of Speed-Up and Efficiency for Pipeline, Super pipeline and Super scalar architecture. What is a SPARC processor? What are the modules in SPARC? Explain each. (8) (5) (7)
