| YY YY | Ikhodi ye-CRCCheck |
Ukuze ubale ikhodi ye-CRC:
1.Irejista ye-16-bit esethiwe ngaphambilini ithi FFFF nge-hexadecimal (okungukuthi, zonke zingu-1).Shayela le rejista ngerejista ye-CRC.
2. XOR idatha yokuqala ye-8-bit enebhithi engezansi yerejista ye-CRC engu-16 futhi ifake umphumela kurejista ye-CRC.
3.Shifta okuqukethwe kwerejista kwesokudla ngebhithi eyodwa (ubheke kwencane), gcwalisa ibhithi ephezulu kakhulu ngo-0, bese uhlola ephansi kakhulu.
4.Uma ibhithi ebaluleke kakhulu ingu-0: phinda isinyathelo sesi-3 (shintsha futhi), uma okuncane okubalulekile kungu-1: irejista ye-CRC ifakwe ku-XORed nge-polynomial A001 (1010 0000 0000 0001).
5. Phinda izinyathelo 3 no-4 kuze kube izikhathi ezingu-8 kwesokudla, ukuze yonke idatha ye-8-bit icutshungulwe.
6.Phinda izinyathelo 2 kuya kwezi-5 ukuze uthole ukucubungula kwedatha okungu-8-bit.
7.Irejista ye-CRC ekugcineni itholakele ikhodi ye-CRC.
8. Uma umphumela we-CRC ufakwa ohlakeni lolwazi, amabhithi aphezulu naphansi ayashintshaniswa, bese kuthi kancane kuqala.
Xhuma inzwa ngokulandela imiyalelo endleleni yokufaka izintambo, bese ufaka izikhonkwane zokuhlola zenzwa emhlabathini ukuze ulinganise umswakama, bese uvula amandla kanye neswishi yokuqoqa ukuze uthole izinga lokushisa lomhlabathi kanye nomswakama endaweni yokulinganisa.
1. Sicela uhlole ukuthi iphakheji iphelele futhi uhlole ukuthi imodeli yomkhiqizo iyahambisana yini nokukhetha.
2. Ungaxhumi uma ukhanyisa, bese uvula ngemuva kokuhlola izintambo.
3. Ungashintshi ngokuzenzakalelayo izingxenye noma izintambo ezidayisiwe lapho umkhiqizo uphuma efekthri.
4. Inzwa iyidivayisi enembayo.Sicela ungayiqaqi uwedwa noma uthinte ingaphezulu lenzwa ngezinto ezicijile noma uketshezi olubolayo ukuze ugweme ukulimaza umkhiqizo.
5.Sicela ugcine isitifiketi sokuqinisekisa nesitifiketi sokuvumelana, futhi usibuyisele kanye nomkhiqizo lapho ulungisa.
1. Uma okukhiphayo kutholwa, isibonisi sibonisa ukuthi inani lingu-0 noma lingaphandle kobubanzi.Hlola ukuthi akukho yini ukuvinjwa kwezinto zangaphandle.Umqoqi angase angakwazi ukuthola ulwazi ngendlela efanele ngenxa yezinkinga zezintambo.Sicela uhlole ukuthi izintambo zilungile futhi ziqinile;
2. Uma kungezona izizathu ezingenhla, sicela uxhumane nomkhiqizi.
