A)
Given Information:
The given code is:
// define structure
square point_color
{
// variable declaration
int c;
int m;
int y;
int k;
};
// declare structure array
struct point_color square[16][16];
int i,j;
// traverse through the array
for(i=0;i<16;i++)
{
//traverse through elements
for(j=0;j<16;j++)
{
//square all elements of the 2-D array
square[i][j].c=0;
square[i][j].m=0;
square[i][j].y=1;
square[i][j].k=0;
}
}
Write hit:
If the information in the cache is reserved or in dirty state then the cache line is updated in its place without updating memory set from its state to dirty.
- If the state of information is in valid state then it executes a write-through operation.
- It then updates the memory and block and changes its blocked state to reserved state.
Write miss:
A partial cache line write is handed as a read miss followed by a write hit. All the other caches are left in the invalid state and the reserved state is occupied by the current state.
B)
Given Information:
The given code is:
// define structure
square point_color
{
// variable declaration
int c;
int m;
int y;
int k;
};
// declare structure array
struct point_color square[16][16];
int i,j;
// traverse through the array
for(i=0;i<16;i++)
{
//traverse through elements
for(j=0;j<16;j++)
{
//square all elements of the 2-D array
square[i][j].c=0;
square[i][j].m=0;
square[i][j].y=1;
square[i][j].k=0;
}

square[i][j].m=0;
square[i][j].y=1;
square[i][j].k=0;
}
