Yintoni i-ECC RAM kwaye isebenza njani?

Kwihlabathi lanamhlanje ledijithali, ukuthembeka kwedatha kunye nokuthembeka kubaluleke kakhulu.Nokuba yiseva, indawo yokusebenza okanye ikhompyuter esebenza kakhulu, ukuqinisekisa ukuchaneka kunye nokuhambelana kolwazi olugciniweyo kubalulekile.Kulapho iKhowudi yokuLungisa impazamo (ECC) RAM ingena khona.I-ECC RAM luhlobo lweinkumbulo ebonelela ngemfezeko yedatha eyomeleziweyo kunye nokhuseleko kwiimpazamo zothumelo.

yintoni kanye kanye ECC RAM?Isebenza njanik?

I-RAM ye-ECC, imfutshane ye-Error yokulungisa i-RAM, imodyuli yememori equlethe i-circuitry eyongezelelweyo ukuze ibone kwaye ilungise iimpazamo ezinokuthi zenzeke ngexesha lokuhanjiswa kwedatha kunye nokugcinwa.Iqhelekileisetyenziswe kwizicelo ezibalulekileyo ezifana neeseva, i-computing yesayensi, kunye namaziko emali, apho neempazamo ezincinci zinokuba nemiphumo emibi.

Ukuze uqonde ukuba njaniI-RAM ye-ECC isebenza, masiqale siqonde ngokufutshane iziseko zememori yekhompyuter.Inkumbulo yofikelelo ngokungacwangciswanga (RAM) luhlobo lwenkumbulo eguquguqukayo egcina okwexeshana idatha ngelixa isetyenziswa yikhompyuter.Xa i-CPU (i-Central Processing Unit) idinga ukufunda okanye ukubhala ulwazi, ifikelela kwidatha egcinwe kwi-RAM.

Iimodyuli ze-RAM zesiNtu(ebizwa ngokuba yi-non-ECC okanye i-RAM eqhelekileyo) sebenzisa i-bit enye kwimemori yeseli ukugcina nokudlulisa idatha.Nangona kunjalo, ezi yunithi zokugcina zithandwa kwiimpazamo zengozi ezinokukhokelela kurhwaphilizo lwedatha okanye ukuphazamiseka kwenkqubo.I-ECC RAM, kwelinye icala, yongeza inqanaba elongezelelweyo lokulungiswa kwempazamo kwimodyuli yememori.

I-RAM ye-ECC yenza ukuba kubonwe imposiso kunye nolungiso ngokusebenzisa amasuntswana ememori eyongezelelweyo ukugcina ukulingana okanye ulwazi lokujonga impazamo.La masuntswana ongezelelweyo abalwa ngokusekelwe kwidatha egcinwe kwiseli yememori kwaye isetyenziselwa ukungqinisisa intembeko yolwazi ngexesha lokufunda nokubhala i-ope.imixhesho.Ukuba impazamo ifunyenwe, i-RAM ye-ECC inokulungisa ngokuzenzekelayo nangokungafihliyo impazamo, iqinisekisa ukuba idatha egciniweyo ihlala ichanile kwaye ingatshintshi.Eli nqaku lahlula i-RAM ye-ECC kwi-RAM eqhelekileyo kuba inika umaleko owongezelelweyo wokhuseleko kwiimpazamo zememori.

Eyona isetyenziswa kakhulu iskimu se-ECC sisilungiso semposiso enye, ubhaqo lwemposiso kabini (SEC-DED).Kwesi sikimu, i-RAM ye-ECC inokuchonga kwaye ilungise iimpazamo ezinokuthi zenzeke kwiiseli zememori.Ukongeza, inokubona ukuba kukho impazamo ephindwe kabini yenzekile, kodwa ayikwazi ukuyilungisa.Ukuba kufunyaniswe imposiso ye-double-bit, inkqubo ikholisa ukuvelisa umyalezo wemposisod ithatha inyathelo elifanelekileyo, elifana nenkqubo yokuqalisa ngokutsha okanye ukutshintshela kwisistim yogcino.

Enye yezinto eziphambili ze-RAM ye-ECC sisilawuli sememori, esidlala indima ebalulekileyo ekubhaqweni kwempazamo kunye nokulungiswa.Umlawuli wememori unoxanduva lokubala kunye nokugcina ulwazi olulinganayongexesha lomsebenzi wokubhala kunye nokuqinisekisa ulwazi olulinganayo ngexesha lokufunda.Ukuba kufunyenwe impazamo, umlawuli wememori unokusebenzisa i-algorithms yemathematika ukumisela ukuba zeziphi iibhithi ezifuna ukulungiswa kunye nokubuyisela idatha echanekileyo.

Kuyafaneleka ukuba uqaphele ukuba i-RAM ye-ECC idinga iimodyuli zememori ezihambelanayo kunye nebhodi yomama exhasa ukusebenza kwe-ECC.Ukuba nawaphi na ala macandelo alahlekileyo, rhoqo non-ECC RAM unakoisetyenziswe endaweni, kodwa ngaphandle kwenzuzo eyongezelelweyo yokubona iimpazamo kunye nokulungiswa.

Nangona i-RAM ye-ECC ibonelela ngezakhono zokulungiswa kwempazamo, ikwanazo ezinye izinto ezingeloncedo.Okokuqala, i-RAM ye-ECC ibiza kancinci kune-RAM engekho ye-ECC eqhelekileyo.I-circuitry eyongezelelweyo kunye nobunzima bokulungisa iimpazamo kubangela iindleko eziphezulu zemveliso.Okwesibini, i-RAM ye-ECC ingenisa isohlwayo esincinci sokusebenza ngenxa yempazamo yokujonga ukubala.Nangona impembelelo ekusebenzeni idla ngokuba yincinci kwaye ihlala ingahoywa, kufanelekile ukuqwalasela izicelo apho isantya sibaluleke kakhulu.

I-RAM ye-ECC luhlobo olukhethekileyo lwememori olubonelela ngentembeko yedatha ephezulu kunye nokukhuselwa kwiimpazamo zothumelo.Ngokusebenzisa i-bits eyongezelelweyo yokujonga iimpazamo kunye ne-algorithms ephezulu, i-ECC RAM inokubona kwaye ilungise iimpazamo, iqinisekise ukuchaneka kunye nokuthembeka kolwazi olugciniweyo.Nangona i-RAM ye-ECC inokubiza kancinci kwaye ibe nempembelelo encinci yokusebenza, ibalulekile kwizicelo ezibalulekileyo apho ukuthembeka kwedatha kubalulekile.
