Question 57
CSNAT2 marksNeeds review
Consider the following two-dimensional array D in the C programming language, which is stored in row-major order:
int D[128][128];
Demand paging is used for allocating memory and each physical page frame holds 512 elements of the array D. The Least Recently Used (LRU) page-replacement policy is used by the operating system. A total of 30 physical page frames are allocated to a process which executes the following code snippet:
for (int i = 0; i < 128; i++)
for (int j = 0; j < 128; j++)
D[j][i] *= 10;
The number of page faults generated during the execution of this code snippet is ________.
