Manje cishe wonke amakhompiyutha afakwe ikhadi lehluzo elidwebile. Le divayisi yenza isithombe esibonakalayo kusikrini sokuqapha. Ingxenye ayilula, kodwa iqukethe izingxenye eziningi ezakha uhlelo olulodwa lokusebenza. Kulesi sihloko sizozama ukutshela ngokuningiliziwe ngazo zonke izingxenye zekhadi levidiyo lesimanje.
Iyini ikhadi levidyo
Namuhla sizobukela amakhadi wevidiyo anamuhla angama-discrete, ngoba okuhlanganisiwe kunomumo ohluke ngokuphelele futhi, ngokuyisisekelo, zakhiwe ngaphakathi kwiprosesa. I-adapter ehluzekile ye-ihluzo ihlinzekwa ngendlela yebhodi lesifunda eliphrintiwe, elifakwe engxenyeni efanele yokwandisa. Zonke izingxenye ze-adapter yevidiyo zikhona ebhodini ngokwazo ngendlela ethile. Ake sihlolisise zonke izingxenye zezingxenye.

Yisho ukuthini ikhadi elihlanganisiwe levidiyo
Iprosesa yezithombe
Ekuqaleni, udinga ukukhuluma ngemininingwane ebaluleke kakhulu ekhadini levidiyo - i-GPU (iprosesa yehluzo). Kule nkampani kuncike ekuvinjeni namandla kuwo wonke idivayisi. Ukusebenza kwalo kuhlanganisa ukucubungula imiyalo ehlobene nehluzo. Iprojekti yegrafu ithatha ukwenziwa kwezenzo ezithile, ngaleyo ndlela ukunciphisa umthwalo ku-CPU, ukukhulula izinsiza zayo kwezinye izinjongo. Uma uphawuleza kakhulu i-video yekhadi levidiyo, amandla amakhulu we-GPU efakiwe kuwo, angakwazi ngisho nokudlula iphrosesa ephakathi ngenxa yobuningi bama-computing units.
Isilawuli sevidiyo
Ukuze isizukulwane sesithombe sikhumbule sifana nesilawuli sevidiyo. Ithumela imiyalo ku-D / A converter futhi isebenza imiyalo ye-CPU. Ikhadi lesimanje linamakhemikhali amaningana akhiwe kuwo: umlawuli wememori yevidiyo, ibhasi yedatha langaphandle nangaphakathi. Ingxenye ngayinye isebenza ngokuzimela, ivumela ukulawula ngesikhathi esisodwa kwezikrini zokubonisa.
Imemori yevidiyo
Ukuze ugcine izithombe, imiyalo, nezici eziphakathi ezingabonakali esibukweni, inkumbulo ethile iyadingeka. Ngakho-ke, ikhadi elilodwa legrafu linememori eningi njalo. Kungaba ngezinhlobo ezahlukene, okuhlukile ngejubane kanye nemvamisa. Thayipha i-GDDR5 okwamanje ethandwa kakhulu, esetshenziselwa amakhadi amaningi anamuhla.
Noma kunjalo, kufanele kukhunjulwe ukuthi ngaphezu kwememori edidiyelwe ekhadini levidiyo, amadivaysi amasha asebenzisa i-RAM efakwe kukhompyutha. Ukuyifinyelela, umshayeli okhethekile usetshenziswa ngebhasi le-PCIE ne-AGP.
D / A okuguqukayo
Isilawuli sevidiyo sakha isithombe, kodwa sidinga ukuguqulwa sibe yisignali edingekayo namazinga athile ombala. Le nqubo yenza i-DAC. Yakhelwe ngesimo sezingqimba ezine, ezintathu zazo ezibhekele ukuguqulwa kwe-RGB (obomvu, obuluhlaza, nohlaza okwesibhakabhaka), futhi ibhuloho lokugcina ligcina ulwazi mayelana nokukhanya okuzayo nokulungiswa kwe-gamma. Isiteshi esisodwa sisebenza emazingeni angu-256 wokukhanya kwembala ngayinye, futhi ngokuphelele, i-DAC ibonisa imibala yezigidi ezingu-16.7.
Imemori engapheli
I-ROM igcina izakhi zesikrini ezidingekayo, ulwazi oluvela ku-BIOS namanye amatafula wesistimu. Isilawuli sevidiyo asibandakanye nganoma iyiphi indlela kanye nedivayisi yokugcina engapheli, ifinyelelwa kuphela yi-CPU. Kungenxa yokugcina ulwazi oluvela ku-BIOS ukuthi i-video yekhadi iqala futhi isebenza ngisho nangaphambi kokuba i-OS ilayishwe ngokugcwele.
Uhlelo lokupholisa
Njengoba wazi, iprosesa nekhadi le-graphics liyingxenye ezishisayo kakhulu kwikhomputha, ngakho-ke badinga ukupholisa. Uma kwenzeka i-CPU, i-cooler efakwe ngokwehlukana, ngakho-ke amakhadi amaningi evidiyo anemishini ye-heatsink nabalandeli abaningana, okuvumela ukugcina izinga lokushisa elincane ngaphansi kwemithwalo esindayo. Amanye amakhadi anamuhla anamandla ashisa kakhulu, ngakho-ke uhlelo lwamanzi olunamandla lusetshenziselwa ukupholisa.

Ukuxhumeka koxhumano
Amakhadi wamagrafu anamuhla afakwe ikakhulukazi nge-HDMI, i-DVI ne-Display Port. Lokhu okutholakele yiyona ehamba phambili kakhulu, esheshayo futhi ezinzile. Ngayinye yalezi zinkimbinkimbi inezinzuzo nezinkinga zayo, ongayifunda ngokuningiliziwe ezihlokweni zewebsite yethu.
Imininingwane eyengeziwe:
Ukuqhathaniswa kwe-HDMI ne-DisplayPort
I-DVI ne-HDMI Ukuqhathanisa
Kule ngqikithi, sichitha idivayisi yekhadi levidiyo ngokuningiliziwe, sihlolisise ingxenye ngayinye ngokuningiliziwe futhi sithole indima yayo kudivayisi. Sithemba ukuthi ulwazi olunikeziwe luwusizo futhi ungafunda okuthile okusha.
