He aha ka mea hana PCI Express? ʻO PCIe, a i ʻole Fast Peripheral Component Interconnect, kahi maʻamau no ka hoʻopili ʻana i nā mea hoʻokomo a me nā mea hoʻopuka (HSIO). Loaʻa i kēlā me kēia motherboard lolouila kiʻekiʻe ka nui o nā slot PCIe hiki iā ʻoe ke hoʻohana e hoʻohui i nā GPU, nā kāleka RAID, nā kāleka WiFi, a i ʻole nā kāleka SSD (solid state drive).
ʻO ka honua hoihoi o ka ʻenehana kāhāhā iā mākou i kēlā me kēia lā me nā holomua hou a me ka hoʻomaikaʻi ʻana i ka hana o kā mākou lako kamepiula. ʻO kekahi o nā mea nui i hoʻololi i ke ʻano o ka kamaʻilio ʻana o nā mea i kekahi, ʻo ia ka PCI Express kaulana. Ma kēia ʻatikala, e wehewehe kikoʻī mākou i nā mea āpau e pono ai ʻoe e ʻike e pili ana i kēia ʻenehana i hōʻailona i mua a ma hope o ka māhele.
He aha ka PCI Express?
ʻO PCI Express, i kapa ʻia ʻo PCIe, kahi maʻamau interconnection kiʻekiʻe i hoʻohana ʻia i nā motherboards kamepiula. Hiki i kēia ʻenehana ke kamaʻilio ma waena o ka CPU a me nā ʻāpana ʻokoʻa like ʻole, e like me nā kāleka kiʻi, nā ʻāpana mālama SSD, nā kāleka pūnaewele, a me nā mea ʻē aʻe. Ua hoʻololi ʻo PCIe i ka maʻamau PCI kahiko, hāʻawi i ka bandwidth kiʻekiʻe a me ka kamaʻilio ʻoi aku ka maikaʻi.
Pehea ka hana ʻana o PCI Express?
ʻAʻole like me ka maʻamau PCI, i hoʻohana i kahi kaʻa like no ka lawe ʻana i ka ʻikepili, hoʻohana ʻo PCI Express i kahi ʻōnaehana kamaʻilio serial. ʻO ia ke ʻano o ka hoʻouna ʻia ʻana o ka ʻikepili i nā ʻeke liʻiliʻi a me ka sequentially, e ʻae ana i ka wikiwiki a me ka maikaʻi o ka hoʻoili ʻana o ka ʻike. Eia hou, hoʻohana ʻo PCIe i kahi ʻōnaehana o nā alahele, ʻo ia nā pilina bidirectional e hoʻouna a loaʻa i ka ʻikepili i ka manawa like.
Nā mana o ka PCI Express
Mai kona hoʻomaka ʻana i ka makahiki 2003, ua ulu ʻo PCI Express ma o nā ʻano like ʻole, hāʻawi kēlā me kēia i ka hoʻomaikaʻi ʻana i ka wikiwiki a me ka hana. Ma lalo, hōʻike mākou i nā mana nui o PCIe:
-
- PCIe 1.0: Ka laulā o 2.5 GT/s no ke alahele.
-
- PCIe 2.0: Ka laulā o 5 GT/s no ke alahele.
-
- PCIe 3.0: Ka laulā o 8 GT/s i kēlā me kēia ala.
-
- PCIe 4.0: Ka laulā o 16 GT/s no ke alahele.
-
- PCIe 5.0: Ka laulā o 32 GT/s no ke alahele.
Nā pōmaikaʻi o PCI Express
ʻO ka lawe ʻia ʻana o PCI Express ua lawe mai me ia i nā pono he nui no nā mea hoʻohana a me nā mea hana lako. ʻO kekahi o nā pōmaikaʻi nui:
- ʻOi aku ka wikiwiki o ka hoʻololi ʻana: Hāʻawi ʻo PCIe i ka bandwidth kiʻekiʻe i hoʻohālikelike ʻia i nā kūlana mua, e ʻae ana i ka kamaʻilio wikiwiki ma waena o nā ʻāpana.
- Laulā: Mahalo i kāna hoʻolālā modular, ala-ala, ʻae ʻo PCIe i ka bandwidth e hoʻoponopono ʻia e like me nā pono kikoʻī o kēlā me kēia ʻāpana.
- Back Compatibility: Ua kūpono kēlā me kēia mana hou o PCIe me nā mana o mua, e maʻalahi ka hoʻololi ʻana a pale i ka obsolescence mua o nā mea.
- Latensi haʻahaʻa: Hoʻemi ke kamaʻilio serial PCIe i ka latency i ka lawe ʻana i ka ʻikepili, hoʻomaikaʻi i ka pane ʻana o ka ʻōnaehana.
Nā noi PCI Express
Ua lilo ʻo PCI Express i de facto standard no ka hoʻohui ʻana i nā ʻāpana like ʻole i loko o ke kamepiula. ʻO kekahi o nā noi maʻamau o PCIe ka:
-
- Kāleka kiʻi: Hoʻohana nā GPU kiʻekiʻe i nā ala PCIe he nui e hoʻonui i ka hana a me ka maikaʻi ʻike.
-
- Nā ʻāpana mālama SSD: Hoʻohana maikaʻi ʻo NVMe SSD i ka wikiwiki o PCIe e hoʻopuka i ka hoʻouka ultra-wikiwiki a me nā manawa hoʻoili ʻikepili.
-
- Kāleka ʻulaʻula: ʻO nā kāleka pūnaewele wikiwiki, e like me 10 Gbps a i ʻole ke kiʻekiʻe, e hoʻohana iā PCIe e hōʻoia i ka bandwidth lawa.
-
- Nā kāleka kani: Hoʻohana nā kāleka kani kiʻekiʻe i ka latency haʻahaʻa o PCIe a me ka bandwidth kiʻekiʻe e hāʻawi i ka maikaʻi o ka leo.
Ma he honua kahi e pono ai ka wikiwiki a me ka hana, Ua hoʻokumu ʻo PCI Express iā ia iho ma ke ʻano he ʻenehana alakaʻi no ka hoʻopili ʻana i nā ʻāpana i kā mākou kamepiula. ʻO kāna hoʻololi mau a me ka hoʻomaikaʻi ʻana i hiki ke pane i nā koi ulu o nā mea hoʻohana a ua kau i nā kumu no ka holomua o ka wā e hiki mai ana i ka ʻāpana helu. I kēia manawa ua loaʻa iā ʻoe ka hoʻomaopopo maikaʻi ʻana i ke ʻano o ka PCI Express a me ke ʻano o ka hana ʻana, hiki iā ʻoe ke mahalo nui i ke koʻikoʻi o kēia maʻamau i kāu hoʻomaikaʻi ʻana a i ʻole kūkulu hou ʻana.
