Sample EC8552 Important 8 mark Questions COMPUTER ARCHITECTURE AND ORGANIZATION :
i).Summarize the eight great ideas of computer Architecture.
ii). Explain the technologies for Building Processors.
2 List the various components of computer system and explain with neat diagram. EC8552 Important 8 Mark Questions Computer Architecture And Organization
i).Define addressing mode.
ii).Describe the basic addressing modes for MIPS and give one suitable example instruction to each category.
Examine the operands and operations of computer hardware. EC8552 Important 8 Mark Questions Computer Architecture And Organization
i).Discuss the logical operations and control operations of computer.
ii). Express the concept of Powerwall processor.
Consider three different 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.
i).Which processor has the highest performance expressed in instructions per second?
ii).If the processors each execute a program in 10 seconds, find the number of cycles and the number of instructions?
iii).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?
Assume a program requires the execution of 50 × 106 FP instructions,110 × 106 INT instructions, 80 × 106 L/S instructions, and 16 × 106 branch instructions The CPI for each type of instruction is 1, 1, 4, and 2, respectively. Assume that the processor has a 2 GHz clock rate. EC8552 Important 8 Mark Questions Computer Architecture And Organization
i).By how much must we improve the CPI of FP instructions if we want the program to run two times faster?
ii).By how much must we improve the CPI of L/S instructions? EC8552 Important 8 Mark Questions Computer Architecture And Organization
iii).By how much is the execution time of the program improved if the CPI of INT and FP Instructions are reduced by 40% and the CPI of L/S and Branch is reduced by 30%?
Recall how performance is calculated in a computer system and derive the necessary performance equations.
i).Formulate the performance of CPU.
ii).Compose the factors that affect performance.
i).Illustrate the following sequence of instructions and identify the addressing modes used and the operation done in every instruction
(1) Move (R5)+, R0
(2) Add(R5)+, R0
(3) Move R0, (R5)
(4) Move 16(R5),R3
(5) Add #40, R5 EC8552 Important 8 Mark Questions Computer Architecture And Organization
ii).Calculate which code sequence will execute faster according to execution time for the following conditions:
Consider the computer with three instruction classes and CPI measurements as given below and instruction counts for each
