He aha te mea te PCI pahi?

He kitea raveraa i roto i te whanaketanga o te hangarau rorohiko - he reira te whakakotahitanga, te whakangāwaritanga hoki kaiwhakanao (heke rererangi) me te whakakotahi whakaaro maha i roto i te mōkihi kotahi. Kahore he mea maere i roto i te meka e tokomaha o ngā kaiwhakamahi o tenei ra, e kore noa e mohio tīmata te mea he PCI pahi. Ko te hunga e kitea te wa o te hanganga o rorohiko IBM-hototahi i runga i te pūtake o 286, 386, me te pera atu. Pūtukatuka, kahore feaa, mahara te nui o ngā potae me atanga pūmārō whakamahia i roto i ngā pūnaha rorohiko o taua wa. Ko te rongonui pahi bit-8 te ISA, ka tona otinga VLB (e mohiotia ana ko VESA), pahi PCI, he tūhono i whakatapua mo pouwhanga pūmanawa Intel, AGP, a na i runga i. a ratou katoa, ki te okotahi onge, i hiahiatia tenei. Tena ko tenei i runga i te kaupapa mīharo "rawakore" - anake kotahi pahi PCI Express, Heoi, whakahōunga rerekē, me te ki tau rerekē o ngā rārangi tohu. Aue, kia utu mo te taua whakakotahitanga, i roto i te tikanga mo'oni, he mea e tika ana ki te kaiwhakamahi mutunga. I muri i te katoa, ara, ki te wātea he, mo te tauira,-kounga tiketike kāri tangi, i te mea he PCI-pūrere, he reira noa wahi ki te kia hono (kore e tatau whāurutau fiemālie), ka whai ki te hoko i te putanga mo te tupare rerekē ranei, atu te tikanga, haere i runga i, whakautu mele, otinga integrated. Ko haamana'oraa o te kōrero o te "kaha" whakawhiti katoa o AGP ki PCI-E te āhuatanga.

He aha te mea PCI pahi kia rongonui? rā hoki ki te 1991, ka te putanga o hua pūtukatuka piha Pentium, ka reira mārama e kore e taea e moka 8-te noa ISA whakarato tahi te auau manakohia o ngā o ngā wāhanga katoa tona hītori. A haamana'o na e i te wa kihai i reira te DMI, ranei Hyper Transport, me te hononga o ngā wāhanga i runga i a kawea atu i roto i te kaupapa i te pahi pūnaha. Ahakoa kua hanga whakamātau ki te circumvent te here te ISA, mo te tauira, me i reira ko te VESA pahi, engari e tika ana ki te here ratou e kore e ora.

I roto i te 1992, i whakaurua Intel PCI pahi i te putanga 1.0 i runga i te paerewa tuwhera. He nui tona auau karaka i te wa te 33 MHz (e auau tauine māmā PTM), i runga i te whakatinanatanga pūmārō, te tautoko 32 ranei 64 paraire (whakaritea ki bit-8 ISA) rānei. Ko te rārangi raraunga ngaohiko i 5 me 3.3, me te hōkaiipurangi ko 133 MB. A, tino nui, kua reira kua tautoko ana Mono & Play (ou'a atu!).

i reira ko te putanga ake o te 2.0 i roto i te 1993.

Kua riro te PCI pahi rongo te ao mai i 1995 (putanga 2.1). Tei runga i te whakatinanatanga ko te auautanga 66 MHz. A, no te whakamahi i te kē 64 bit whakahaere i roto i tenei 533MB whakawhitinga mauiui. Windows 95 ka haere ki te whakaora, i te pae hopea, ki te whakarite tino te mahi tika o te whakaaro PCI ki Mono & hangarau Play. tukua Tohu raina ki te neke i 5V ki 3.3V

Next i tukua ai whakahounga 2.2 - 3.0. Tūhono i roto i te putanga 2.2 i te "kī" e poraka te tāutanga o ngā pūrere hotokore ngaohiko. tonu te wahi 2.3 ki te 3.3 V, na te whakamahi o taua whakaaro i roto i te putanga ki te 2.1 (5) hua i roto i te kino ki te kāri, me te tahi mau taime te mauiui. I roto i te 3.0 putanga 5 V te kore whakamahia.

I roto i te 1997, i ki te whawhati ake rite kua te taua pahi Intel AGP kua tukua mo te ataata, e kore i taea e nei i tae o ratou pūmanawa tonu i runga i te PCI te PCI.

Na te PCI pahi, rite kī mua, kei te tata kore whakamahia, whakakapia e tona mono - PCI Express. Ko te taua te tikanga pūmanawa whakatutuki, engari kua pehia te whakatinanatanga tinana huringa nui. maha o conductors, kua puta ke te auau whakahaere e nui haere (me ki whakaiti nāianei). Kei te puta ke hoki Tikanga o te whirihora i te tīmata tauwhitinga (pūrere hono), tuku watea atu ki te hapai i to ratou tono ki te pahi.

E te ara, i runga i te tahi mau Motherboards tonu taea ki te whakatau i te tūhono pahi PCI. Heoi, i runga i kahore e ki te tautoko taketake o te chipset me te pūtukatuka korero - i roto i tenei whakatinanatanga tikanga whakamahi i te maramara motuhake ko te piriti e whakatītaha tono ki te PCI PCI Express.
