Consider the following $\text{C}$ function executed in an $\text{OS}$ with paging where the page size is $4$ kilobytes. Further, assume that the system employs a $32-$ entry direct mapped $\text{TLB}$
int *alloc_and_init()
{
int counter, value = 0, size = 2048;
int *new_ptr = malloc(size * sizeof(int));
/* Assume sizeof(int) = 4 and new_pyr is 4KB aligned */
for(counter = 0; counter<size; new_ptr++, counter++)
*new_ptr = value;
return new_ptr;
}
Assuming no page faults and no context switches during execution of the program, what is the number of $\text{TLB}$ misses during the execution of the for loop?
- $2048$
- $2$
- $0$
- $1$
