The system has a direct-mapped cache with total data size of 8192 bytes and block size of 16 bytes. Assume the cache starts out empty. For the following piece of code, which of following statements are correct? (Note: Assume that int is of 32-bits (4 bytes); variables x and i are both in registers and the array A is in memory.)

int A[256];
int x = 0;
for (int i = 0; i < 256; i++) {
    x += A[i];
}
