          For the following code segment, apply the loop optimization techniques to improve the code quality: 
1) code motion, 
2) loop unrolling, 
3) loop fusion

for (i = 0; i < N * 2; i++)
    a[i] = b[i] * c[i];

for (j = 0; j < N * 2; j++)
    m[j] = m[j] + 5;

Step 1

int n2 = N*2; for(i=0; i<n2; i++) a[i] = b[i] * c[i]; for(j=0; j<n2; j++) m[j] = m[j] + 5; Show more…
