What is TLB for? Why TLB? Given the following number, what is theeffective memory access time?

vodomira [7]

Answer:

A lookaside buffer translation (TLB) is a memory cache that reduces the time it takes to access a user memory place. TLB includes the most lately used page table entries.

TLB is used to overcome the issue of sizes at the time of paging. Page Table Entry (PTE) is used for framing the memory ,but it uses two references one for finding the frame number and the other for the address specified by frame number.

Formula for finding effective memory access time-

Effective Memory Access Time = (TLB access_time+Memory Access Time)*hit ratio + (TLB access_time+2*Memory Access Time)*(miss ratio)

Given in question,

Hit ratio = 0.90

Memory Access Time = 150ns

TLB access time= 5ns

Effective Memory Access Time = (TLB access_time+Memory Access Time)*hit ratio + (TLB access_time+2*Memory Access Time)*(miss ratio)

=(5+150) * 0.90 + (5+2*150)*(1-0.90)

=155 * 0.90 + (305*0.1)

=139.5 + 30.5

= 170ns

A perfect binary tree is a complete binary tree with all levels fully filled. Add a method in the BST class to return true if th

algol [13]

Answer:

class BST {

static class Node

{

int val;

Node left, right;

}

static boolean checkPerfectBT(Node node, int h, int d)

{

if (node == null)

return true;

if (node.left == null && node.right == null)

{

if(h==d+1)

return true;

else

return false;

}

if (node.left == null || node.right== null)

return false;

return checkPerfectBT(node.left, h, d+1) && checkPerfectBT(node.right, h, d+1);

}

static int height(Node node)

{

int dep = 0;

while (node != null)

{

node = node.right;

dep=dep+1;

}

return dep;

}

static boolean isPerfectBT(Node node)

{

int h = height(node);

return checkPerfectBT(node, h, 0);

}

static Node addNode(int x)

{

Node node = new Node();

node.val= x;

node.right = null;

node.left = null;

return node;

}

public static void main(String args[])

{

int i,j,k;

Node node= null;

node = addNode(34);

node.left = addNode(2);

node.right = addNode(322);

node.left.left = addNode(21);

node.left.right = addNode(23);

node.right.left = addNode(37);

node.right.right = addNode(54);

if (isPerfectBT(node) == true)

System.out.println("This is a Perfect Binary tree");

else

System.out.println("This is Not a perfect Binary Tree");

}

Explanation:

Calculate the depth of BST by using a while loop until it reaches a null value.
In the addNode method, make an object of Node class.
In the main method, pass the values to addNode method.
Finally display the relevant message to show if it's Perfect or not.

Create a Sub called "daisyDecisions" that runs when you click a button. In this sub, you will create a program that determines w

jenyasd209 [6]

Answer:

see explaination

Explanation:

Please find the screenprint and the VBA code. As shown in the screenprint, range B1 is used to enter the number of petals. If you want to use a different cell for petals input, then change the code accordingly.

Also, the VBA code is placed in the Sheet1 module. No new modules are inserted.

Screenprint: see attachment for screenshot

VBA Code:

Private Sub CommandButton1_Click()

Call daisyDecisions

End Sub

Private Sub daisyDecisions()

Dim remainder As Integer

Dim noOfPetals As Integer

noOfPetals = Sheet1.Range("B1").Value

remainder = noOfPetals Mod 2

If remainder <> 0 Then

MsgBox "He/She loves you!!!"

Else

MsgBox "He/She loves you not!!!"

End If

End Sub
