Ndi kompyuta ndi zithunzi khadi Kodi

Nthawi zina, ukonde angapezeke funso "kodi zithunzi khadi." Ngakhale kuti zikuwoneka zazing'ono Komabe, munthu amene akufuna kumvetsa tiyenera kulemekeza, monga amayesetsa kumvetsa ndi chipangizo kompyuta.

Aliyense akudziwa kuti ntchito zipangizo zonse kompyuta zochokera chifaniziro bayinare mfundo. Amene anaona ndi ndondomeko ya ziro ndi anthu anachokera pa pepala kapena kompyuta, amadziwa kuti pali kumvetsa kuti chinachake kuli kovuta. Izi mosavuta, chifukwa chakuti kanjedza onsewa - mtundu wa yaying'ono-Ops kwa transistors. ndi ubale pamwambapa, funso zimene khadi zithunzi chiyani? Direct! Kodi timaona pa TV ndi mkati kompyuta digito deta mitsinje n'kukhala otchulidwa kuzindikira anthu. Vuto la kusintha basi anatumizidwa khadi kanema.

Tiyeni chimatanthauza mfundo "kodi zithunzi khadi." Video adaputala (zithunzi khadi) - chipangizo cholinga kusonyeza zithunzi pa zenera (ofanana bwanji ndi zipsera chosindikizira pa pepala). Komanso, osati deta onse digito, ndipo mwa njira inayake anakonza. Mwachitsanzo, ngati inu kuyesa kuonetsa mtsinje digito malamulo yovuta litayamba kudzera video, ndiye kanthu zimachitika. Onse deta mkati ndi chisanadze okonzeka ndi CPU kwa chipangizo lililonse chandamale: anasonyezera basi anakhumba adiresi zikusonyezedwa ndi zina zotero.

Koma koposa zonse amangonena za mbali mapulogalamu Choncho, kuganizira kwambiri munthu amaganiza, ife sitingakhoze kuyankha mwatsatanetsatane kuti "kodi zithunzi khadi." Thupi, ndi kuwonjezeka gulu kuti mapulagi mu dzenje lolingana (kagawo) wa mavabodi (mainboard). Pafupifupi onse adaputala azamagetsi ano kanema anapangidwa kwa a PCI Express.

The zigawo zotsatirazi muli pa bolodi: a zithunzi purosesa, Mtsogoleri, video khadi kukumbukira (RAM ndipo ROM), basi cholumikizira ndi linanena bungwe cholumikizira, DAC, yozizira dongosolo, m'munsili zinthu. Mu ena zitsanzo, mndandanda angathe ndi zigawo zina.

magawo kanema kwakukulukulu anatsimikiza mtima anasintha likutipatsa purosesa. kupanga ulipo zambiri awiri makampani - AMD (ATI), ndipo NVIDIA. The gawo ina ing'onoing'ono, ngakhale odziwika Intel komanso akuyesetsa kudzatenga nawo amachita msika.

zithunzi purosesa (GPU) wakhala kulenga chithunzi deta imene ntchito. chiwerengero cha transistors kuposa chithunzi ichi ndi purosesa chapakati, zomwe zimasonyeza kuti pali ntchito zake zosayerekezeka. Mwa njira, ichi ndi chifukwa koposa mungapeze mapulogalamu apadera kuti achite kuwerengetsera pa GPU lapansi. Inde, Masewero ndi ntchito kupyolera mwayi operekedwa (PhysX, DirectCompute) kalekale anaphunzira mmene angagwiritsire ntchito kwa masamu, si kulingalira.

Mtsogoleri ndi tasked mogwirizana ndi kukumbukira komanso mabasi mkati ndi kunja. Pang'ono pang'ono basi mkati - ndi chithunzi chachiwiri pambuyo kufunika ntchito GPU. Tsopano anagawira zitsanzo kuchokera 64, 128, 256 kapena kuposa Akamva. Tatenga zosakwana 128 ali osavomerezeka.

Kukumbukira pa khadi zithunzi chofunika kwa yosungirako ndiponso pokonza wa zithunzi analengedwa ndi GPU ndi kutsogolera linanena bungwe kwa chophimba. Yodziwika ndi mtundu tchipisi anaika (DDR - GDDR5) ndi buku. Njira yachangu kubwera ndi GDDR5. masewera Modern amafuna osachepera 512 MB voliyumu (zimadalira zoikamo).

Aliyense khadi ali, monga tanenera kale, lakonzedwa kwa tayala yeniyeni. Tsopano chimagwiritsidwa ntchito PCI Express 16. Nthawi zina pali PCI, koma apamwamba mtengo. Zaka zingapo zapitazo, makompyuta analamulira ku AGP basi, koma Intel, monga nthawi yonse, mu nthawi kupasula izo.

O cholumikizira imalongosola ndi mawonekedwe imene mukhoza kutumiza mbendera Muziona. Ambiri mwa anthuwa: chakale D-Sub, digito DVI masiku ano HDMI, aoneke Port, ndi zina zotero.

Nthawi zina zithunzi khadi ndi mbali ya CPU, mu nkhani iyi, amagwiritsa ntchito dongosolo yokumbukira, ndi cholumikizira linanena bungwe ndi soldered pa mavabodi lapansi. The ntchito njira amenewa amapereka Anzawo kunja.
