CASE II AziTech is considering the design of a new CPU for its new model of computer systems for 2021. It is considering choosin

g between two (2) CPU (CPUA and CPUB) implementations based on their performance. Both CPU are expected to have the same instruction set architecture. CPUA has a clock cycle time of 60 ns and CPUB has a clock cycle time of 75 ns. The same number of a particular instruction type is expected to be executed on both CPUs in order to determine which CPU would executes more instructions. CPUA is able to execute 2MB of instructions in 5*106 clock cycles. CPUB executes the same number of instructions in 3*106 clock cycles. a) Using the MIPS performance metric, which of the two (2) CPU should be selected to be implemented in the new computer system. Justify your choice. b) Compute the execution time for both CPUs. Which CPU is faster?

Answer:

(a)The CPU B should be  selected for the new computer as it has a low clock cycle time which implies that it will implement the process or quicker when compared to the CPU A.

(b) The CPU B is faster because it executes the same number of instruction in a lesser time than the CPU A .

Explanation:

Solution

(a)With regards to  the MIPS performance metric the CPU B should be chosen for the new computer as it low clock cycle time which implies that it will implement the process or quicker when compared to the CPU A and when we look at the amount of process done by the system , the CPU B is faster when compared to other CPU and carries out same number of instruction in time.

The metric of response time for CPU B is lower than the CPU A and it has advantage over the other CPU and it has better amount as compared to CPU A, as CPU B is carrying out more execution is particular amount of time.

(b) The execution can be computed as follows:

Clock cycles taken for a program to finish * increased by the clock cycle time = the Clock cycles for a program * Clock cycle time

Thus

CPU A= 5*10^6 * 60*10^-9 →300*10^-3 →0.3 second (1 nano seconds =10^-9 second)

CPU B= 3 *10^6 * 75*10^-9 → 225*10^-3 → 0.225 second

Therefore,The CPU B is faster as it is executing the same number of instruction in a lesser time than the CPU A

Write a Java class with the following methods: getArray(int numStrings) is an instance method that takes command line input (use
mezya [45]

Answer:

Follows are the code to this question:

import java.util.*;//import packae for user-input  

public class Main//defining a class Main

{

public String[] getArray(int numString)//defining a method getArray

{

String[] name=new String[numString];//defining array of String values

Scanner in = new Scanner(System.in);// creating scanner class object for input values from user-end

for(int i=0;i<numString;i++)//defining for loop for input multiple values

{

System.out.print("Enter String Value :");//print message

name[i]=in.nextLine();//input values

}

return name;//return array values

}

public String getLongestString(String[] sArray)//defining a method getLongestString

{

int m=0,mi=0; //defining integer variables

for(int i=0;i<sArray.length;i++)//defining for loop for check the longest value in array

{

if(m<sArray[i].length())//defining if block that checks m varaible value greater then sArray length  

{

m=sArray[i].length();//use m to hold sArray length

mi=i;//use max_index to hold i that is loop value

}

}

return sArray[mi];//return Longest value

}

public static void main(String[] args)//defining main method

{

Main s=new Main();//Creating object of main class    

String[] n;//defining string variable n  

n=s.getArray(5);//use n varaible to call getArray method and store its value

System.out.println("Longest value is: "+s.getLongestString(n));//use print method to call getLongestString method

}

}

Output:

please find attached file.

Explanation:

In the given java program code, inside the main class two method that is "getArray and getLongestString", is defined, in which the "getArray" method uses an integer variable in its parameter and inside the method, an array is defined that use a  scanner class for input array value.

  • In the "getLongestString" pass as a parameter and inside the method, two integer variable "m and mi" is defined that use in the loop to return the longest string value.
  • In the class main method is to define that creates a class object and call the above method and use the print method to return its value.

Consider the partially-filled array named a. What does the following loop do? (cin is a Scanner object)int[] a = {1, 3, 7, 0, 0,
boyakko [2]

Answer:

Option 1: May crash at runtime because it can input more elements than the array can hold

Explanation:

Given the code as follows:

  1.        int[] a = {1, 3, 7, 0, 0, 0};
  2.        int size = 3, capacity = 6;
  3.        int value = cin.nextInt();
  4.        while (value > 0)
  5.        {
  6.            a[size] = value;
  7.            size++;
  8.            value = cin.nextInt();
  9.        }

From the code above, we know the <em>a</em> is an array with six elements (Line 1). Since the array has been initialized with six elements, the capacity of the array cannot be altered in later stage.

However, a while loop is created to keep prompting for user input an integer and overwrite the value in the array started from index 3 (Line 4- 9). In every round of loop, the index is incremented by 1 (Line 7). If the user input for variable <em>value</em> is always above zero, the while loop will persist.  This may reach a point where the index value is out of bound and crash the program. Please note the maximum index value for the array is supposedly be 5.
