8. When using PP and PW instructions to update consecutive bytes, optimized timings are obtained with one sequence
including all the bytes versus several sequences of only a few bytes (1 ≤ n ≤ 256).
9. int(A) corresponds to the upper integer part of A. For instance, int(12/8) = 2, int(32/8) = 4 int(15.3) =16.
