imposo yekwanda ddr5

Imathiswe ephindwe kabili (DDR5) iyinkimbetho ebalulekileyo kwegenereshini entsha yememory technology, enquma ukuba kuzwa kwiintsuku zokusebenza ngoku. Le mathiswe aphela kwiimodali zememory DDR5 kunye nokunika impakho kwindawo yokusebenza kanye ne-stability. Inkqubo yokuqinisekisa nokulungisa imathiswe kwi- DDR5 isebenzisa i-ECC (Error Correction Code) esemgceni, eyenekile ngaphandle kwezakhelo zemotherboard. Esi gqibhela leso sethu kulungisa imathiswe ngexesha elilinganayo emva kokuthiwa kwingxaki, oku kuyahlula intshisekelo yedatha kunye ne-stability yensimbi. Imathiswe ephindwe kabili (DDR5) ayilungiswa ngokudla kwiziganeko zokulungisa imathiswe, njengoko ke DFE (Decision Feedback Equalization) kunye nemigca engenziwanga okuqhelekisa ubude bokugcina kumanyano aphezulu. Itheknoloji yenziwa nge-CRC kunye ne-ECC ukuphela kwiimilayezo/amacala, ukuqinisekisa ukuba kukho indlela efanelekileyo yokuhlolwa kunye nokulungiswa komathiswe. Le ndawo kuyindlela ngokukhawuleza kwiintsuku zokusebenza ngaphezulu, izicathami zedatha kunye nezixhobo zentsebenziso apho ikona yedatha iyinkimbetho. Indlela lomgca wokusebenza ngazo le mathiswe kuyenza into ebalulekileyo kwindawo yokusebenza ngoku kuzo zonke iintlobo, ngako ke kufuneka kujolisekwe kuzo zonke izinto ezisebenzayo.

Ukuphatha imathimba ye-DDR5 kubona amanye amapho yezimpawu ehlukile futhi engavumelela ngokweqile kumaqine eminye. Okuqukethwe kakhulu kukusebenzisa i-ECC engaphakathi, okunikeza uhlobo oludlule lomphathi wemathimba. Le ndawo isebenza ngendlela esibonile kanye ne-ECC yokuhamba kwesistimu, futhi kube yimali eliwaka ukuphatha imathimba. Imikhiqizo yesistimu yokudetectionsa imiphumela ebucayi ingalela nokulungisa imiphumela engabili ngokushesha, nasekuveleni kwezimpawu eziningi ukuzikhombisa ukuba kusobala ukwenza isistimu. Le ndlela ethuthukisayo yokuphatha izimpawu ikanciphisa ukungabi nomfanekiso wezimpawu. Okunye kwamapho okubaluleke kukuvikwa okuningi kwamandla, okukunciphisa ukunduluka komthwalo phakathi kwezinkinga ngokwenza uhlobo lwezimpawu lube khona ngokuqondile. Ukuvikwa okulinganiselwe kwe-CRC kwiindlela zokubiza kuvikela ukuthi izenzo zemathimba zenziwa ngendlela efanele, futhi kube yimali elingelwa ukuthi isistimu iyashasha noma kungenjani. Izindlela DDR5 zokuphatha izimpawu ziyagcinwa kakhulu ekusebenzeni kwezinto ezibalulekile lapho ukugcinwa kwezimpawu kuyadingeka. Ukuchithwa kwezimpawu ngokwendawo nezistimu kunezinhla yokuthula, lokhu kuyafuna isitolo esingu-Enterprise, izistimu eziphethe okuphezulu, nezindawo zokugcina imathimba. Ukuvikwa okuningi kwezimpawu nokulungisa kunezinhlanu zokusebenza kahle kwezistimu ngokujwayele, ngoba kungabi nomkhawulo wezimpawu ongcono, okuvikela ukuthi kube nenkomo eyengeziwe yokusebenza kwezimpawu.

Ukusebenzisa kwe-ECC esikoleni

I-Error Correction Code (ECC) esikoleni se-DDR5 ikhombisa indlela entsha yokuphatha imemo eriphuthelwe. Le ndlela enqunyiwe isebenza kumeme esicatheni ngasinye, nokuwakala nokulungisa ngokuzuzwayo okungazibopheki ukusebenzisa i-ECC evela kulo mbhodi wesistimu. Le mpumelelo inciphise amandla we-ECC owodwa ngaphakathi kwesicathu ngasinye, ekuvumela ukuphambuka nokulungisa okungazibopheki ngaphambi kokudlula idatha kumoduli wememori. Le nto iyahlisa ngokusobala umugqa wecorruption yedatha ukuze kube lula ukuvikela sistimu yonke. I-ECC esikoleni inako ukulungisa iziphoso zokugcina elinye ngesikhathi futhi ibhale amagama esiye aphuthelwe ngaphezulu okuhlanganisa nezinye iziphoso eziningi, ekuvumela ukuba kune-integrity yedatha ebangelwa ngaso sonke isikhathi. Le ngxenzo inethongwa kakhulu emazingeni ephezulu yokusebenza kwamagxobo lapho ikhono lokucaciswa kwe data kuyinkimbinkimbi.

Ukuphatha Amandla Okunye Nokuphepha Kwesinye

Isisitemi sokuphatha amandla kumemori yeDDR5 siphathelene ngendlela ebalulekile ekugcineni kwezimo zokubetha nasekustableni kwesicelo. Ngokusebenzisa ukulawulwa okuhle kwegolide nezindlela zokulethwa amandla, iDDR5 ikhumbula ukuphepha okufanayo kwegolide noma lapho kuzahlukahluka izinsuku. Isisitemi sokuphatha amandla esetshenzisweni ifaka phakathi izilawuli zegolide ezithunyelwe kumodoli yememori ngokwabo, okuncipisa umshelo nokuvalwayo kwesinye okungaba yizindlela zokubetha. Le sisitemi esetshenziswe yokulethwa amandla ikhombisa ukusebenza okuphephile emaphakathi wezimo zokusebenza fanele nake kugcina kwezimo zokubetha ahlobene nezingxenye zokuthwala amandla. Lokhu kwezokwenza teknoloji kanye nokusetshenziswa kamehlo amathiselwano nasekuqaleni kwegolide (Decision Feedback Equalization) ukugcina ubungako bwegolide, okuyindlela ebaluleke kakhulu xa isebenza emaphakathi wezinsuku phezu kwezinkomba lapho kungenzeka ukuphepha kwesinye kudinga ukucinwa ngendlela ehlukahlukene.

Uhlelo Lokugcinwa Izimo Zobubi

Ukuphila kwe-architecture ye-DDR5 yemiphumela yokuhlinzeka kwedatha kuyindlela ebalulekileyo yokugcina ubungovu bedatha. Isisitemu isebenza ngemikhawulo engaphezu kwekuphila, kunale ukusebenza kwe-CRC ukulawula amanani nezithuba zokungenisa, i-ECC yedoti yedoti, nokusebenza kwemiphumela yesisitemu. Le ndlela lebalulekile ikhipha ukuthi imiphumela ikhutshelwe futhi ikwakhiwe kuzinye izindawo, kusukela kuchip yedathi kuya kuhlanganweni lwezisitemu. Le architecture inamathikithi amabiye wekuthiwa nokuqala emiphumeleni, ekuvumela abasebenzisi ukulandelela nokuhlola izinhlobo zemiphumela ngokuvulekile. Le ndlela yokuphila engaphandle kokuphila kwezinye izinhlobo kuyindlela ebaluleke kakhulu ezifundazeni lapho isikhathi esiyiyanzelelayo sesisitemu nobungovu bedatha yingxenye encane.
