Assume that we have a 32KB data cache with 32-byte blocks. Elements of two 4x200 arrays A and B are 8 bytes long. The data cache is initially empty and there will be no capacity and conflict misses. Calculate the number of times the prefetch instructions are executed in the following loop. Also calculate the number of data cache misses.

for (i = 0; i < 4; i++)
for (j = 0; j < 200; j++)
{
prefetch(A[i][j+7]);
prefetch(B[i][j+7]);
A[i][j] = A[i][j] + B[i][j];
}
