Hurongwa bhazi

The Hurongwa bhazi rakagadzirirwa Implementation munhu kukurukurirana processor kune kwokunze mano ari kombiyuta pachishandiswa chinokosha kuzvidzora mano - adapters kana controllers. All ichangoburwa chokuita negadziriro bhazi achishandisa neezvitendero connectors. Tires inogona kupatsanurwa muzvikamu zvitatu maererano Mabasa avo: kero, mashoko uye kuzvidzora, izvo zvakasiyana shoko urefu, kureva nhamba Data achipfuura pavo. Zvaimirirwa mudziyo dzinongoita pakutsvaga nokukurumidza ane PC.

The Hurongwa bhazi unogona kushanda nenzira inotevera inokosha mitemo: MCA, ISA, VESA, eIsa, PCI. Kwenguva refu, ISA bhazi anoonekwa kuva mumwe mureza mumunda pachavo makombiyuta. Pokuikurukura pachishandiswa masere-ikakuruma hurongwa bhazi ari IBM ari PC XT uye IBM PC. Rakanga akapa sere kudimburira mitsetse kuti interfacing pamwe zvokunze namano, uyewo vana mitsetse kuwana ndangariro zvakananga.

Basa hurongwa bhazi uye microprocessor chinozoiswa pamusoro kakawanda 4,77 MHz. A nokukurumidza date yedzimudzangara chingava anenge 4,5 MB por wechipiri. In runotevera makombiyuta rave richishandiswa hexadecimal bhazi, izvo imhaka 24 kero mitsetse kubvumirwa kuita zvakananga nyaya negondobwe, apo saizi raro 16 MB.

In ichi bhazi nezvitanhatu Hardware anomisa Rakashandiswsa pachinzvimbo sere, apo nhamba migero kuti mbune mashoko kare Kunoumbwa masere pane ina. Zvino bhazi anoshanda asynchronously kuti microprocessor ari kakawanda 6 MHz, uye izvi zvakaita kuti vawedzere nokupfuuridzirwa kumhanya kusvika 16MB pasekondi yoga yoga. Zvino iye akapiwa mukana wokushanda yakaderera-nokukurumidza mano, asi haana kugona kupa vakarongeka kushanda ano mano. It kukanganiswa nokuti michina pakubhadhara itsva yezvinhu mabhazi.

Muna 1987 zvakanzi vakava hurongwa bhazi ISA, iyo yakava wokutanga mukuru-unongotaura. It chakasiyana kuti ayo kumhanya yaiva 10 MHz uye bhazi pacharo rashanduka 32-yati, iyo yakawedzera kuchinjwa mwero 20 MB muzana wechipiri. Zvisinei, nokuda kusapindirana pakati vhiri zvakanga zvisingaiti kushandisa controller nokuda ISA bhazi, nekuti icho mapurani asina kuwanikwa nyanya kushanda.

The Hurongwa bhazi eIsa yakazokudziridzwa muna 1989, yakava pakutsanangura shanduro ISA. Kunoitawo kuti dzinoisa mashoko connectors kwete chete dzavo controllers, asiwo vaya ISA. It aishanda kakawanda 8-10 MHz, apo pakukwanisa kwayo 32, vachibvumira zvakananga kuna 4 GB, kuwana ruzivo Gengi 33 Mbytes por wechipiri. A zvakaipira bhazi iri nhamba yakaderera iri kupanana ruzivo kubudiswa Graphics, mifananidzo, uye mutengo huri akakwirira controllers.

The PCI bhazi rakanga rakagadzirirwa itsva processor Pentium, asi anogonawo kushandiswa pane mamwe platforms. Kunoitawo kuti dzaiitirwa pachako kuti akasiyana mano gumi. bhazi iri rinoshandiswa humboo uchatamisa 32 kana 64, uye nokubata nokukurumidza yakanga 132 uye 264 MB por wechipiri.

Zvino maitiro mapuranga chokuita nevamwe mano nomukombiyuta AGP bhazi, izvo rinobvumira Graphics kadhi kushandisa RAM PC. Akakwanisa kutsungirira Graphics ano, izvo zvinofanira kufambisa tarisisa kumhanya chaizvo, chii chinonetsa kugadzirisa PCI. Kana kushandisa PCI akaratidza kukodzera kuwedzera kuyeuka pamusoro vhidhiyo nokuda shoma nokukurumidza uye bhazi bandwidth. Frequency AGP hurongwa bhazi anobvumira kupanana ruzivo pakati maitiro kuyeuka uye nemavhidhiyo ndangariro zvakananga, risingagoni kubudirira kana uchishandisa zvimwe zvinodiwa kuti mano izvi.
