I218 Computer Architecture

Report 1

Question 1

(1) Find the yield for a die that is 1.4cm on a side, assuming that a die is square and “the defects per area” of 0.40 per cm². (0.5 pt.)

(2) Suppose that a die is enlarged from 1.4cm on a side to 1.7cm on a side. (A die is square). Find the yield for this new die. (0.5 pt.)

(3) The yield derived in (2) is unacceptable since it leads to much higher costs. What much should “defects per area” be improved for a die with 1.7cm on a side to keep the yield as good as that in (1) ?. Answer the value of the “defects per area”. (0.5 pt.)

(4) Suppose that the die area (1.7cm on a side) and the “defects per area” are ones derived in (3), that “wafer diameter” is 20.0cm, and that “cost per wafer” is 10,000yen. Calculate the “cost per die” by using the following formulas. (The units for diameter and area are “cm” and “cm2”, respectively.) (1pt.)

Question 2 计算机结构体系课业代写代做

Consider two different implementations, P1 and P2, for the same instruction set. P1 has a clock rate of 2.0 GHz. P2 has a clock rate of 3.0 GHz.

There are five classes of instructions (A, B, C, D and E) in the instruction set. The average number of cycles for each instruction class for P1 and P2 is shown in the right table.

(1) Assume that the total number of instructions executed in a certain program is I , and I instructions are divided equally among the classes of instructions except for class A which occurs twice as often as each of the others. Calculate the execution times, in seconds, of P1 and P2. (by using the symbol “I ”) (0.5 pt.)

(2) How much faster is P2 than P1 ? (0.5 pt.)

Question 3 计算机结构体系课业代写代做

You are the lead designer of a new processor. The processor design is complete, and now you must decide whether to produce the current design as it stands or spend additional time to improve it. You discuss this problem with your hardware engineering team and arrive at the following options:

a. Leave the design as it stands. Call this base machine Mbase. It has a clock rate of 1.0Ghz, and the following measurements have been made using a simulator:

b. Optimize the hardware. The hardware team claims that it can improve the processor design to give it a clock rate of 1.2 GHz. Call this machine Mopt. The following measurements have been made using a simulator for Mopt:

(1) What are the CPIs for Mbase and Mopt ? (0.5 pt.)

(2) What are the native MIPS ratings for Mbase and Mopt ? (0.5 pt.)

(3) How much faster is Mopt than Mbase ? (0.5 pt.)
