Si loo xisaabiyo summada CRC:
1. Diiwaanka hore ee 16-bit waa FFFF ee hexadecimal (yacni, dhamaantood waa 1).Wac diwaankan diiwaanka CRC
2.XOR xogta 8-bit ee ugu horreysa oo leh waxoogaa yar oo ka hooseeya 16-bit CRC diiwaanka oo geli natiijada diiwaanka CRC.
3.U rog waxa ku jira diiwaanka midig hal xoogaa (dhanka hoose), ku buuxi inta ugu sareysa 0, oo hubi inta ugu hooseysa.
4.Haddii inta ugu yar ee muhiimka ahi ay tahay 0: ku celi tillaabada 3 (isbeddel mar kale), haddii inta ugu yar ee muhiimka ahi ay tahay 1: Diiwaanka CRC waxa lagu XOR oo wata A001 badan (1010 0000 0000 0001).
5. Ku celi tillaabooyinka 3 iyo 4 ilaa 8 jeer dhanka midig, si xogta 8-bit oo dhan la habeeyo.
6. Ku celi tillaabooyinka 2 ilaa 5 habaynta xogta 8-bit ee xigta.
7.Diiwaanka CRC ee ugu dambeyntii la helay waa lambarka CRC.
8. Marka natiijada CRC la geliyo qaab-dhismeedka macluumaadka, waxaa la isweydaarsadaa xoogaa sare iyo mid hooseeya, kan hoosena waa marka hore.
Ku xidh dareemaha sida ku cad tilmaamaha habka fiilooyinka, ka dibna geli baadhista dareemayaasha ciidda si aad u cabbirto heerkulka, oo aad u keento tamarta ururiyaha iyo dareeraha si aad u hesho heerkulka biyaha ee barta cabbirka.
