Consider the two computers A and B with the clock cycle times 100 ps and 150 ps respectively for some program. The number of cyc

les per instruction (CPI) for A and B are 2.0 and 1.0 respectively for the same program. Which computer is faster and how much? a) A is 1.33 times faster than B b) Bis 1.22 times faster than A c) A is 1.23 times faster than B d) B is 1.33 times faster than A

Answer:

Option d) B is 1.33 times faster than A

Given:

Clock time, t_{A} = 100 ps

t_{A} = 150 ps

No. of cycles per instructions,  n_{A} = 2.0

n_{B} = 1.0

Solution:

Let I be the no. of instructions for the program.

CPU clock cycle, f_{A} = 2.0 I

CPU clock cycle, f_{B} = 1.0 I

Now,

CPU time for each can be calculated as:

CPU time, T = CPU clock cycle\times clock time

T_{A} = f_{A}\times t_{A} = 2.0 I\times 100 = 200 I ps

T_{B} = f_{B}\times t_{B} = 1.0 I\times 100 = 150 I ps

Thus B is faster than A

Now,

\frac{Performance of A}{Performance of B} = \frac{T_{A}}{T_{B}}

\frac{Performance of A}{Performance of B} = \frac{200}{150}

Performance of B is 1.33 times that of A

Clock cycle times of Computer A  =100ps

Number of cycle per instruction (CPI) = 2

Time Required Per instruction = Clock times * CPI =100 * 2 = 200 ps

clock cycle times of Computer B =150ps

Number of cycle per instruction(CPI) = 1

Time Required Per instruction = Clock times * CPI 150 * 1 = 150 ps

Computer B requires less time than Computer A per instruction

So, Computer B is Faster

Computer B is Faster 200 - 150 = 50ps Faster Per instruction

Write a procedural programming loop.. Your loop should start variable n with a value of 10 and count down to zero. The loop shou
anastassius [24]

Answer:

//Here is the for loop in C.

for(n=10;n>0;n--)

{

   printf("count =%d \n",n);

}

Explanation:

Since C is a procedural programming language.Here if a loop that starts with n=10; It will run till n becomes 0. When n reaches to 0 then loop terminates otherwise it  print the count of n.

// here is code in C++.

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{  // variables

int n;

// for loop that runs 10 times

// when n==0 then loop terminates

for(n=10;n>0;n--)

{

   cout<<"count ="<<n<<endl;

}

return 0;

}

Output:

count =10

count =9

count =8

count =7

count =6

count =5

count =4

count =3

count =2

count =1
