Exercise Program - 9 IMPLEMENTATION OF MEMORY MANAGEMENT SCHEME II -PAGING

AIM:

To write a C program to implement paging concept for memory management.

ALGORIHTM:

Step 1: Start the program.

Step 2: Enter the logical memory address.

Step 3: Enter the page table which has offset and page frame.

Step 4: The corresponding physical address can be calculate by,

PA = [ pageframe* No. of page size ] + Page offset.

Step 5: Print the physical address for the corresponding logical address.

Step 6: Terminate the program.

PROGRAM:

#include

int main()

{

int lpage[10], pagetab[10], pframe[2][2], I,j;

int size, msize, cnt, t,k,pos,logadd,m=0;

int frameno;

long int l;

int i;

printf("\nEnter the memory size:");

scanf("%d", &msize);

printf("Enter the pase size:");

scanf("%d", &size);

cnt=(msize/size);

printf("\nEnter the logical page: ");

for(j=0;j

{

scanf("%d", &lpage[j]);

}

t=0;

k=0;

for(j=0;j

{

printf("\n");

if(t

{

printf("%d value is %d\n", t,lpage[j]);

t++;

}

else

{

t=0;

printf("%d value is %d\n", t,lpage[j]);

t++;

}

}

printf("\nEnter the page table value: ");

for(i=0;i

{

scanf("%d", &pagetab[i]);

}

printf("\nEnter the logical address: ");

scanf("%d", &logadd);

for(k=0;k

{

if(logadd==lpage[k])

{

pos=(k/size);

m=k%size;

break;

}

else

continue;

}

printf("\nPage number : %d", pos);

frameno=pagetab[pos];

printf("\nThe frame number is %d\n", frameno);

printf("\nThe corresponding physical address is %d", (frameno*size)+m);

}

SAMPLE OUTPUT:

[it65@AntiViruS ~]$ cc paging.c

[it65@AntiViruS ~]$ ./a.out

Enter the memory size:4

Enter the page size:2

Enter the logical page: 2

3

4

5

0 value is 2

1 value is 3

0 value is 4

1 value is 5

Enter the page table value: 101

102

Enter the logical address: 5

Page number : 1

The frame number is 102

The corresponding physical address is 205

RESULT:

Thus C program for implementing paging concept for memory management has been executed successfully.
