For some program, compiler A produces a program with a dynamic instruction count of 109 instructions and execution time of 1.1 seconds, while compiler B produces a program with a dynamic instruction count 1.2*109 and execution time of 1.5 seconds. Find an average CPI for each program given that the processor has a clock cycle time of 10-9 seconds. You must show the computations that lead to the answer.

 = 1.1

= 1.25

Explanation:

How to calculate the CPI generated by each compiler

we need to use the following formula

CPI=(CPU Clock cycle/Instruction count)

=(1.1s/(1 x 10s-9)) (1/(1 x 109)

=1.1

=(1.5s/(1 x 10s-9)) (1/(1.2 x 109))

=1.25

answer and explanation;

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
