PART-B
1.      i)Discuss in detail about Eight great ideas of computer Architecture.(8)
ii) Explain in detail about Technologies for Building Processors and Memory (8)
2.      Explain the various components of computer System with neat diagram (16)
3.      Discuss in detail the various measures of performance of a computer(16)

4.      Define Addressing mode and explain the basic addressing modes with an example for each.
5.  Explain operations and operands of computer Hardware in detail (16)

6.      i)Discuss the Logical operations and control operations of computer (12) ii)Write short notes on Power wall(6)

7.   Consider three diff erent processors P1, P2, and P3 executing the same instruction

set. P1 has a 3 GHz clock rate and a CPI of 1.5. P2 has a 2.5 GHz clock rate and a CPI of 1.0. P3 has a 4.0 GHz clock rate and has a CPI of 2.2.
a.  Which processor has the highest performance expressed in instructions per second?
b.   If the processors each execute a program in 10 seconds, find the number of
        cycles and the number of instructions.
c. We are trying to reduce the execution time by 30% but this leads to an increase of 20% in the CPI. What clock rate should we have to get this time reduction?
     8.Assume a program requires the execution of 50 × 106 FP instructions,110 × 106 INT instructions, 80 ×            106 L/S instructions, and 16 × 106 branchinstructions. The CPI for each type of instruction is 1, 1, 4, and 2,        respectively.Assume that the processor has a 2 GHz clock rate.

     a.  By how much must we improve the CPI of FP instructions ifwe want the program to run two times            faster?

    b.  By how much must we improve the CPI of L/S instructionsif we want the program to run two times              faster?

    c.  By how much is the execution time of the program improvedif the CPI of INT and FP instructions is         reduced by 40% and the CPI of L/S and Branch is reduced by 30%?
   9.Explain Branching operations with example
  10.Explain the following addressing modes in detail with diagram

       i)Immediate addressing
       ii)Register addressing, 
       iii)Baseor displacement addressing, 
      iv)PC-relative addressing 
      v)Pseudodirect addressing
