The only data accesses are loads and stores, and these total 50% of the instructions. If the miss penalty is 25 clock cycles and the miss rate is 2%, how much faster would be the computer is if all instructions were cache hits? What is THUMB? How THUMB instructions are executed by ARM? Is it advantageous? (6) What is Super scalar architecture? Is it faster than Super pipeline architecture? Draw a Time-Space diagram for comparison. What do you mean by Speed-Up of pipeline? Derive equations of Speed-Up and Efficiency for Pipeline, Super pipeline and Super scalar architecture. (4) What is a SPARC architecture? What are the data types of SPARC? What is Interconnection network? Draw a Butterfly network and explain the communication mechanism. (5) (5) (4) (6) a) b) Distinguish and Differentiate. Array processor Vs. Vector processor I/O bus Vs. Memory bus (5) (5) a) b) Justify your answer. Whether loosely coupled multiprocessor is multicomputer? Whether ARM is RISC architecture?
