PCI Express chii ichocho

Chii chinonzi PCI Express mudziyo⁢? PCIe, ‍ kana Fast Peripheral Component Interconnect, chiyero chekubatanidza chekubatanidza yakakwira-kumhanya kupinza uye kubuda (HSIO) zvikamu. Imwe neimwe yepamusoro-inoshanda komputa mamaboard ine akati wandei PCIe slots yaunogona kushandisa kuwedzera maGPU, makadhi eRAID, WiFi makadhi, kana mamwe SSD (solid state drive) makadhi.

Nyika inonakidza yetekinoroji inotishamisa mazuva ese nekufambira mberi kutsva uye kuvandudzwa mukuita kwemidziyo yedu yemakomputa. Chimwe chezvinhu zvakakosha zvakashandura nzira yekutaurirana kwemidziyo kune yakakurumbira PCI Express Kana iwe wakambozvibvunza kuti chii chaizvo uye kuti inoshanda sei, iwe uri munzvimbo chaiyo. Muchikamu chino, tichatsanangura zvakadzama zvese zvaunoda kuziva nezve tekinoroji iyi yakamaka pamberi uye mushure muchikamu.

Chii chinonzi PCI Express?

PCI Express, inozivikanwawo sePCIe, ndeye yakakwirira-kumhanya yekubatanidza chiyero inoshandiswa mumakombuta mamabhodhi. Iyi tekinoroji inobvumira⁤ kutaurirana pakati pe⁢ CPU uye zvakasiyana zvinhu zvehardware, zvakaita semakadhi emifananidzo, maSSD ekuchengetera zvikamu, makadhi etiweki, pakati pezvimwe. PCIe yakatsiva yekare PCI chiyero, ichipa yakakwira bandwidth uye kutaurirana kwakanaka.

Ko PCI Express inoshanda sei?

Kusiyana nePCI standard, iyo yakashandisa bhazi rakafanana pakufambisira data, PCI Express inoshandisa serial yekutaurirana system. Izvi zvinoreva kuti data inotumirwa mumapakiti maduku uye sequentially, zvichibvumira kukurumidza kukuru uye kubudirira mukufambisa kwemashoko. Pamusoro pezvo, PCIe inoshandisa sisitimu yenzira, dziri mbiri dzekubatanidza kutumira uye kugamuchira data panguva imwe chete.

PCI Express shanduro

Kubva payakatangwa muna 2003, PCI Express yakashanduka kuburikidza neshanduro dzakasiyana, imwe neimwe ichipa kuvandudzwa maererano nekumhanya uye kushanda. Pazasi, isu tinopa iwo makuru mavhezheni ePCIe:

• • PCIe 1.0: Bandwidth ye2.5 GT/s panzira.

• • PCIe 2.0: Bandwidth ye5 GT/s panzira.

• • PCIe 3.0: ⁢Bandwidth ye8 GT/s per⁢ nzira.

• • PCIe 4.0: Bandwidth ye16 GT/s panzira.

• • PCIe 5.0: Bandwidth ye32 GT/s panzira.

Zvakanakira zvePCI Express

Kugamuchirwa kwePCI Express kwakaunza akawanda mabhenefiti kune vashandisi uye vagadziri vehardware. Zvimwe zvezvakanakira ndezvi:

• Yepamusoro yekumhanyisa kumhanya: PCIe inopa yakakwira bandwidth kana ichienzaniswa neyakapfuura zviyero, ichibvumira kukurumidza kutaurirana pakati pezvikamu.
• Scalability: Kutenda kune yayo modular, nzira-yakavakirwa dhizaini, PCIe inobvumira bandwidth kuti igadziriswe zvinoenderana nezvinodiwa chaizvo zvechikamu chimwe nechimwe.
• Back⁢ Kuenderana: Imwe neimwe vhezheni itsva yePCIe inoenderana neshanduro dzakapfuura, zvichiita kuti shanduko ive nyore uye kudzivirira kudhara kwezvikamu.
• Lower latency: PCIe serial kutaurirana inoderedza latency mukufambiswa kwedata, inovandudza kuita kwehurongwa.

PCI Express Applications

PCI Express ⁢ yave iyo de facto chiyero chekubatanidza zvinhu zvakasiyana mukombuta. Zvimwe zvezvinonyanya kushandiswa zvePCIe zvinosanganisira:

• • Makadhi emifananidzo: MaGPU epamusoro-soro anoshandisa nzira dzakawanda dzePCIe kuti awedzere kuita uye kunaka kwekuona.

• • SSD kuchengetedza zvikamu: NVMe SSDs inotora mukana wekumhanya kwePCIe kuendesa yekupedzisira-yekukurumidza kurodha uye nguva dzekufambisa data.

• • Network cards: Makadhi etiweki epamusoro-soro, akadai se10 Gbps kana kupfuura, shandisa PCIe kuona yakakwana ⁢bandwidth.

• • Makadhi eruzha: Makadhi epamusoro-ekupedzisira anonzwika anotora mukana wePCIe's low latency uye yakakwira bandwidth kuendesa yepamusoro odhiyo mhando.

Munyika ⁤ umo kumhanya nekuita kwakakosha,⁢ PCI Express yakazvisimbisa seyo inotungamira tekinoroji yekubatanidza zvinhu mumakomputa edu. Kushanduka kwayo nguva dzose uye kuvandudzwa kwaita kuti zvikwanise kupindura kune zviri kukura zvinodiwa nevashandisi uye zvakateya nheyo dzekufambira mberi mune ramangwana muchikamu chekombuta. Iye zvino zvawave nekunzwisisa zvirinani kuti PCI Express chii uye kuti inoshanda sei, iwe unozogona kuonga zvakanyanya kukosha kweiyi chiyero mukuvandudza kwako kwemidziyo kana kuvaka.
