b)
Explanation of Solution
Number of bits present in the physical address:
- The memory system is byte addressable.
- A page contains 8 bits.
- Total number of page=8 pages
- Total number of bits=64 bytes
- Number of frame=4.
Represent the bits in the binary format:
4 frames can be represented as 22...
c)
Explanation of Solution
Physical address that corresponds to virtual address:
To represent the physical address that corresponds to the virtual address it is required to convert the given hexadecimal numbers into 9 bits equivalent binary number.
| Hexadecimal number | 9 bit binary number |
MSB (last three) | Decimal equivalent | validation | Physical address | ||
| 0x00 | 000 | 00 | 0000 | 000 | 0 | Contained in frame 1 | 01000000 |
| 0x44 | 001 | 00 | 0100 | ||||

Methods (Ch6) - Review
1. (The MyRoot method) Below is a manual implementation of the Math.sqrt() method in Java.
There are two methods, method #1 which calculates the square root for positive integers, and
method #2, which calculates the square root of positive doubles (also works for integers).
public class SquareRoot {
public static void main(String[] args) {
}
// implement a loop of your choice here
// Method that calculates the square root of integer variables
public static double myRoot(int number) {
double root;
root=number/2;
double root old;
do {
root old root;
root (root_old+number/root_old)/2;
} while (Math.abs(root_old-root)>1.8E-6);
return root;
}
// Method that calculates the square root of double variables
public static double myRoot(double number) {
double root;
root number/2;
double root_old;
do {
root old root;
root (root_old+number/root_old)/2;
while (Math.abs (root_old-root)>1.0E-6);
return root;
}
}
