DDR4 Sdram - Gutangiza, Guhugura no Guhindura

DDR4 SDRAM: Moteri yo kubara kijyambere

Mwisi yisi yikoranabuhanga ryubucuruzi, umuvuduko nubwizerwe ntibishobora kuganirwaho. Ku mutima wa buri-imikorere-yimikorere ya seriveri, akazi, hamwe na progaramu ya progaramu yibeshya sisitemu yo kwibuka, kandi kumyaka, DDR4 SDRAM (Double Data Rate 4 Synchronous Dynamic Random-Access Memory) yabaye ishingiro ryayo. Mugihe abakoresha babona ibisubizo byanyuma - kubona amakuru byihuse no gukora ibintu byinshi - ibiba inyuma yinyuma ni ballet igoye yubuhanga bwuzuye. Uburozi nyabwo bwa DDR4 ntabwo buri mumuvuduko wabwo gusa ahubwo muburyo bukomeye bwo gutangiza, guhugura, no guhinduranya bibaho igihe cyose sisitemu ikora. Kubucuruzi bukoresha urubuga rukomeye nka Mewayz modular yubucuruzi ya OS, gusobanukirwa iyi fondasiyo ni urufunguzo rwo gushima ubutare bukomeye n’imikorere itwara ibikorwa bya buri munsi.

Urukurikirane rwa Boot-Up: Imbaraga-Kuri no Gutangiza

Urugendo rwa DDR4 rutangira umwanya ukanze buto ya power. Bitandukanye n'ubwoko bworoshye bwo kwibuka, DDR4 ntabwo ikanguka yiteguye gukora. Birasaba gukomera, intambwe ku yindi intangiriro yo gutondekanya byateguwe nu mugenzuzi wibuke, ubusanzwe byinjijwe mubice bitunganya hagati (CPU). Iyi nzira ningirakamaro mugushiraho itumanaho ryibanze. Umugenzuzi abanza gukoresha imbaraga no guhagarika ibimenyetso byisaha. Ihita itanga urukurikirane rwamabwiriza yo kuzana ububiko bwa module kuva muri passiyo ya reta kuri reta aho bashobora kwakira amabwiriza akomeye. Igice cyingenzi cyiki cyiciro ni ugusoma chip ya Serial Presence Detect (SPD) chip kuri module yibuka ubwayo. Chip ya SPD ikubiyemo amakuru yingenzi yateguwe nuwabikoze, nkubucucike bwa module, ibipimo byigihe, nibisabwa na voltage. Umugenzuzi yibuka akoresha aya makuru nkigishushanyo mbonera kugirango yimenyekanishe neza, yemeza ko "avuga ururimi rumwe" na RAM. Ikosa iryo ari ryo ryose hano rishobora kuganisha ku kunanirwa gutangira, kwerekana impamvu guhuza ari byo byingenzi.

Guhana ukuboko: Impamvu imyitozo yo kwibuka ari ngombwa

Iyo ibipimo fatizo bimaze gushyirwaho, sisitemu ihura ningorabahizi: igihe cyigihe. Kuri umuvuduko mwinshi wa gigabit kumasegonda DDR4 ikora, ibimenyetso byamashanyarazi biva kumugenzuzi ujya kuri chip yibuka ninyuma birashobora guhinduka nabi kubera itandukaniro rito muburebure bwumurongo kurububiko nibindi bintu bifatika. Iyo bidakosowe, iyi skew yatuma ruswa yangirika hamwe na sisitemu. Kugira ngo iki kibazo gikemuke, DDR4 ikora inzira yitwa imyitozo yo kwibuka . Mugihe cyamahugurwa, umugenzuzi yibuka akora urukurikirane rwo gusoma no kwandika ibizamini, ahindura neza igihe cyibimenyetso byacyo. Ihuza neza gutinda kwa data strobe (DQS) ugereranije numurongo wamakuru (DQ) kugirango irebe ko mugihe umugenzuzi atanze amakuru, aba ayifata kumwanya uhamye neza mukuzenguruka kwikimenyetso. Iyi nzira ntabwo igenwa rimwe muruganda; bibaho muri buri boot imwe kugirango yishyure impinduka zibidukikije nkimihindagurikire yubushyuhe, byemeza imikorere yizewe umunsi kumunsi.

Amahugurwa yo kwibuka niyo ntwari itavuzwe ya sisitemu itajegajega. Ni kalibibasi yacecetse ihindura ikosa rishobora kuba ryihuza mumihanda yizewe, yihuta yamakuru yihuta, akaba aribwo buryo bukomeye umusingi ukomeye urubuga nka Mewayz rwubakiyeho.

Guhuza neza imikorere yimikorere: Soma kandi wandike Calibration

Kurenga igihe cyambere cyo guhindura imyitozo, sisitemu yo gukora cyane ikunze kwishora mubindi kugirango ihindure imipaka yihuta kandi neza. Uburyo bubiri bukomeye bwo guhinduranya ni Kwandika Urwego na VREF (Reba Umuvuduko). Andika Urwego rusubizaho itandukaniro ryigihe hagati yikimenyetso cyisaha hamwe na command / adresse yerekana ibimenyetso bitandukanye muburyo bwo kwibuka. Ibi byemeza ko iyo inyandiko yoherejwe yoherejwe, igera kuri chip yibuka icyarimwe. Calibibasi ya VREF irarenze. Umuvuduko wa VREF ni urwego rukomeye umugenzuzi yibuka akoresha kugirango amenye niba ikimenyetso cyumvikana 1 cyangwa 0. Mugihe umuvuduko wiyongera kandi urwego rwa voltage rugabanuka, intera yamakosa iba nto. VREF Calibration igenda isanga icyerekezo cyiza cya voltage yerekanwe kugirango ugaragaze ibimenyetso byuzuye kubisomwa byombi. Kubucuruzi bukoresha amakuru yibanda cyane kuri Mewayz, izi kalibibasi zemeza ko ibyuma byibanze byateguwe neza kugirango bitange amakuru hamwe nukuri kandi bitinze.

Ibyiza byingenzi bya sisitemu ya DDR4 ikwiye neza

Iyo gutangira, imyitozo, hamwe na kalibrasi byuzuye neza, ibisubizo ni sisitemu yo kwibuka ikora mubushobozi bwayo. Inyungu nibyingenzi mubikorwa remezo byubucuruzi bigezweho:

• Yizewe Yizewe: Amakosa yagabanijwe cyane yamakuru arinda impanuka za porogaramu na ruswa, biganisha kuri sisitemu nini cyane.
• Imikorere ikoreshwa neza: Sisitemu irashobora gukora ku muvuduko wamamajwe nta guhungabana, byemeza ko porogaramu zitanga umusaruro n’ibikoresho byo gusesengura byakiriwe ku mbuga nka Mewayz bisubiza ako kanya.
• Kunonosora neza: Imiterere yimikorere yiyi nzira ituma sisitemu ikora neza hamwe nurwego runini rwa DDR4 kuva kubacuruzi batandukanye.
• Iterambere rirerire: Mugutoza kuri buri boot, sisitemu ihora ihuza ibidukikije, ikomeza kwizerwa mubuzima bwibikoresho.

Mu gusoza, inzira zinonosoye inyuma ya DDR4 yibuka nubuhamya bwubuhanga bukenewe kuri mudasobwa igezweho. Iyi si yihishe yo gutangiza, guhugura, hamwe na kalibrasi nibyo bitanga umusingi uhamye, wimikorere-mwinshi ubucuruzi bushingiraho. Amahuriro nka Mewayz, ahuza ibikorwa bitandukanye byubucuruzi muri sisitemu ikora idafite gahunda, biterwa ahanini nibi bikoresho byizewe kugirango bitange uburambe bwabakoresha. Igihe gikurikira sisitemu yawe itangiye vuba kandi ikora neza, ibuka imbyino igoye ya digitale yatumye byose bishoboka.

Ibibazo bikunze kubazwa
