. Suppose an instruction takes 1/2 microsecond to execute (on the average), and a page fault takes 250 microseconds of processor

saul85 [17]

Answer:

a. 100.

b. 31500.

Explanation:

So, we are given the following data which is going to help in solving this particular question.

The time required to execute (on the average) = 1/2 microsecond , a page fault takes of processor time to handle = 250 microseconds and the disk time to read in the page = 10 milliseconds.

Thus, the time taken by the processor to handle the page fault = 250 microseconds / 1000 = 0.25 milliseconds.

The execution time = [ 1/2 microseconds ]/ 1000 = 0.0005 milliseconds.

The number of Pages sent in a second by the disc = 1000/10 milliseconds = 100.

Assuming U = 1.

Hence, the disc transfer time = [2/3 × 1 } + [ 1/3 × 0.25 milliseconds + 15 ] × 2.

=0.667 + 15.083.

= 15.75 millisecond.

Average number of instruction = 15.75/0.0005 = 31500.

How does a push system differ from a pull system?

sergeinik [125]

Well if were talking about computer cooling, push system is like it seems pushing air into the computer, pull system is taking out air!! the best systems have both to get the optimal cooling possible!!!

Write an x86_64 Assembly program that sorts a programmer-defined array. The size of the array and the address of the array shoul

sashaice [31]

Answer:

Check the explanation

Explanation:

Algorithm –

Load data from offset 500 to register CL (for count).

Travel from opening memory position to last and evaluate the two numbers if first number is bigger than second number then we will have to swap them.

First pass fix the position for last number.

Decrease the count by 1.

Again travel from opening memory position to (last-1, by help of count) and compare 2 numbers if second number is smaller than that of the first number then swap them.

Second pass fix the position for last two numbers.

Repeate.

Step by step Explanation –

MOV SI, 500: set the value of SI to 500.

MOV CL, [SI]: load data from offset SI to register CL.

DEC CL: decrease value of register CL BY 1.

MOV SI, 500: set the value of SI to 500.

MOV CH, [SI]: load data from offset SI to register CH.

DEC CH: decrease value of register CH BY 1.

INC SI: increase value of SI BY 1.

MOV AL, [SI]: load value from offset SI to register AL.

INC SI: increase value of SI BY 1.

CMP AL, [SI]: compares value of register AL and [SI] (AL-[SI]).

JC 41C: jump to address 41C if carry generated.

XCHG AL, [SI]: exchange the contents of register AL and SI.

DEC SI: decrease value of SI by 1.

XCHG AL, [SI]: exchange the contents of register AL and SI.

INC SI: increase value of SI by 1.

DEC CH: decrease value of register CH by 1.

JNZ 40F: jump to address 40F if zero flat reset.

DEC CL: decrease value of register CL by 1.

JNZ 407: jump to address 407 if zero flat reset.

HLT: stop.
