Design (draw a datapath) for a block that will help your processor decide whether to take a branch for different conditions. As

input, your block will be given an opcode for the type of branch and signals from the ALU which perform the actual comparisons. Your block will produce a single signal branch as output.
Inputs:
• zero - 1 if R[rs1] - R[rs2] = 0, 0 otherwise
• lt - 1 if R[rs1] < R[rs2], 0 otherwise
• opcode (2b) - 00: beq (==), 01: bne (!=), 10: blt (<), 11: bge (>=)

Output:
• branch - 1 if branch should be taken, 0 if not

Answer:

See explaination

Explanation:

Here are the steps taken to draw the diagram!

opcode0 and the opcode1 signals are inverted/not to determine the case whether it is 00, 01, 10, 11.

Then they are 'and'ed with the corresponding Zero/lt signal to confirm if the case is true, for eg. zero = 1 if opcode = 00 (beq).

Then all the cases are 'or'ed to get the Branch signal!

See attachment for the diagram

Which of the following function declarations correctly expect an array as the first argument?
NARA [144]

Answer:

Only

Option: void f1(float array[], int size);

is valid.

Explanation:

To pass an array as argument in a function, the syntax should be as follows:

functionName (type arrayName[ ] )

We can't place the size of the array inside the array bracket (arrayName[100]) as this will give a syntax error. The empty bracket [] is required to tell the program that the value that passed as the argument is an array and differentiate it from other type of value.

In Java.Use a single for loop to output odd numbers, even numbers, and an arithmetic function of an odd and even number. Use the
rosijanka [135]

Answer:

<em>This program is written using java programming language</em>

<em>Difficult lines are explained using comments (See Attachment for Source file)</em>

<em>Program starts here</em>

import java.util.*;

import java.lang.Math;

public class oddeven{

public static void main(String [] args)

{

 double even,odd;//Declare variables even and odd as double

 //The next iteration prints odd numbers

 for(int i = 1;i<=173;i+=2)

 {

  odd = i;

  System.out.format("%.4f",odd);//Round to 4 decimal places and print

System.out.print("\t");

 }

 System.out.print('\n');//Start printing on a new line

 //The next iteration prints even numbers

 for(int i = 0;i<=173;i+=2)

 {

  even=i;

  System.out.format("%.4f",even);//Round to 4 decimal places and print

System.out.print("\t");

 }

 System.out.print('\n');//Start printing on a new line

 double  ssqrt;//Declare ssqrt to calculate the square root of sum of even and odd numbers

 for(int i = 0;i<=173;i+=2)

 {

  ssqrt = Math.sqrt(2*i+1);//Calculate square root here

  System.out.format("%.4f",ssqrt); //Round to 4 decimal places and print

System.out.print("\t");

 }

}

}

Explanation:

Libraries are imported into the program

import java.util.*;

import java.lang.Math;

The following line declares variables even and odd as double

double even,odd;

The following iteration is used to print odd numbers  with in the range of 0 to 173

for(int i = 1;i<=173;i+=2)  {

odd = i;

System.out.format("%.4f",odd); This particular line rounds up each odd numbers to 4 decimal places before printing them

System.out.print("\t"); This line prints a tab

}

The following code is used to start printing on a new line

System.out.print('\n');

The following iteration is used to print even numbers  with in the range of 0 to 173

for(int i = 0;i<=173;i+=2)

{

even=i;

System.out.format("%.4f",even); This particular line rounds up each even numbers to 4 decimal places before printing them

System.out.print("\t"); This line prints a tab

}

The following code is used to start printing on a new line

System.out.print('\n');

The next statement declares ssqrt as double to calculate the square root of the sum of even and odd numbers

double  ssqrt;

for(int i = 0;i<=173;i+=2)

{

ssqrt = Math.sqrt(2*i+1);This line calculates the square root of sum of even and odd numbers

System.out.format("%.4f",ssqrt); This particular line rounds up each even numbers to 4 decimal places before printing them

System.out.print("\t"); This line prints a tab

}
