Kluczowym elementem przykładu są rozkazy wewnątrz pętli, a jak wygląda pętla dookoła oraz ile bajtów sumujemy, to jest w tym miejscu b. mało ważne, chodzi o ideę i o to, żeby jej nie zaciemniać przez zoptymalizowanie pętli pod (np.) konkretny rozmiar bloku. Wiadomo, że SIO robi to jeszcze nieco inaczej, bo nie jest tak, żeby bloki miały tylko 128, 256 i 512 bajtów. Wiadomo też, że każdy koder sobie to przystosuje do szczegółowych wymogów swojego programu. [[Użytkownik:KMK|KMK]] 20:58, 19 sty 2011 (CET)</ins></div></td></tr> </table>
