3. Copy a short integer array of certain length. Use the sample code on slide 39 of LectureWeek7and8.pdf as a template.

void copy1(short X[], short Y[], int N)

{

int i;

for (i = 0; i < N; i++) {

Y[i] = X[i];

}

}

4. Copy a 64-bit integer array of certain length. You should use LDMxx and STMxx instructions.

void copy2(int64_t *Y, int64_t *X, intN)

{

for (int i = 0; i < N; i++) {

*Y++ = *X++;

}

}

Note: The about C function is equivalent to the following C code:

void copy2(int64_t Y[], int64_t X[], intN)

{

for (int i = 0; i < N; i++) {

Y[i] = X[i];

}

}
