Ubuyobozi buhebuje kuri USB4 Kuva kuri 40Gbps Umuvuduko, Umuyoboro wa Dynamic Umuyoboro wuzuye-Imikorere imwe-Umuyoboro
Kuva USB4 yagaragara, twagiye dusohora ingingo nyinshi nu murongo wo gusangira amakuru afatika. Nyamara, ibyamamare byabaye byinshi kuburyo abantu aho bari hose babaza isoko rya USB4. Guhera mugihe cyambere USB 1.0 hamwe na 1.5Mbps yohereza amakuru, USB yanyuze mubisekuru byinshi. Habayeho ibisobanuro byinshi nka USB 1.0, USB 2.0, na USB 3.0, kandi imiterere ya interineti hamwe na gahunda yo gushushanya harimo USB Type-A, USB Type-B, hamwe na USB Type-C ikunze kugaragara cyane, n'ibindi. Irashobora guhuza ibikoresho hafi ya byose neza kandi ikabishyuza. Niba terefone yawe, mudasobwa, monitor, printer, nibindi byose bishyigikira USB4, hanyuma mubyukuri, ukeneye gusa umugozi wamakuru ushyigikira USB4 kugirango uhuze ibikoresho, bigatuma ibiro byo murugo byoroha cyane. Ntabwo ukeneye kugura insinga zitandukanye zo guhindura insinga. Kubwibyo, USB4 irashobora gutuma uburyo bwacu bwo gukora butandukana kandi bworoshye. Mubyongeyeho, ikindi kintu kidasanzwe kiranga USB4 nuko biteganijwe ko kizakoreshwa mubikoresho byifashishwa mu kubara ubwenge.
01 USB4 na USB3.2
USB 3.2 nigipimo gishya cyasohowe numuryango USB-NIBA. Yatangijwe mubyukuri guhera muri Nzeri 2017. Urebye tekiniki, USB 3.2 ni iterambere kandi ryiyongera kuri USB 3.1. Impinduka yibanze nuko umuvuduko wo kohereza amakuru wongerewe kuri 20 Gbps, kandi interineti iracyakurikiraUbwoko-Cgahunda yashizweho mugihe cya USB 3.1, ntagishyigikira Ubwoko-A na Type-B. USB4 na USB3.2 zombi zikoresha interineti-C, ariko USB4 iraruhije cyane. USB4 ishyigikira icyarimwe no kwakira icyarimwe-kwakira, PCI Express® (PCIe®), DisplayPort amajwi / amashusho, hamwe na USB binyuze mumashusho amwe ya Type-C kumurongo umwe. Babiri USB4 bashobora guhanahana amakuru yamakuru ya IP binyuze muri host-to-host tunnel; DisplayPort na USB ya tunnel isobanura ko amajwi, amashusho, amakuru, nimbaraga zishobora koherezwa binyuze mumurongo umwe, bikaba byihuse kuruta gukoresha USB3.2. Mubyongeyeho, ihererekanyabubasha rya PCIe rirashobora gutanga umurongo mwinshi, ubukererwe buke, kandi ukagera kubintu byinshi mububiko bunini cyane, ubwenge bwimbaraga, nibindi bikoreshwa.
USB4 ihuza imiyoboro ibiri yo kohereza no kwakira muri interineti imwe ya USB-C, hamwe nigipimo cya 20 Gbps na40 Gbps, kandi buri muyoboro urashobora kugira igipimo cyamakuru agera kuri 10 Gbps cyangwa 20 Gbps. Kubateza imbere chip, aya makuru ni ngombwa cyane. Bakeneye kumenya ko muburyo bwa Thunderbolt3, igipimo cyamakuru kuri buri muyoboro no kohereza ni 10.3125 Gbps cyangwa 20.625 Gbps. Muburyo busanzwe bwa USB, umuyoboro umwe wohereza / kwakira abantu ukora ku gipimo cya5 Gbps (USB3.0) or 10 Gbps (USB3.1), mugihe imiyoboro ibiri ya USB3.2 ikora ku gipimo cya 10 Gbps.
Kubijyanye no kuramba, ibice bitwara imbaraga bigize interineti-C ni cyane cyane icyuma cyo hanze, kikaba gikomeye kandi kidakunze kwangirika. Umuyoboro wamakuru wo hagati urinzwe nigifuniko cya arc, bigatuma kwangirika bigoye. Igishushanyo gisabwa cyerekana koUSB Ubwoko-CIrashobora kwihanganira amacomeka arenga 10,000 hamwe nugucomeka bitarangiritse. Niba ubaze ushingiye kumacomeka 3 no gucomeka kumunsi, interineti ya USB Type-C irashobora gukoreshwa byibuze imyaka 10.
02 Kwihutisha Kohereza USB4
Nyuma yo gusohora kumugaragaro porotokole ya USB 3.2, umuryango wa USB wahise utangaza ibisobanuro bya USB 4 mugihe gito. Bitandukanye n'ibipimo byabanjirije nkaUSB 3.2. Izi nimpinduka nini mugutezimbere USB mumyaka mirongo ishize. Iyo ukoresheje Type-C umuhuza muguhuza, imikorere ya USB4 isimbuza USB 3.2, na USB 2.0 irashobora gukora icyarimwe. USB 3.2 Yongerewe imbaragaSS yihuta ikomeza ibikorwa remezo byo kohereza "USB data" kumurongo wa USB 4. Itandukaniro rinini hagati ya USB4 na USB 3.2 riri muri iyo USB4 ihuza-yerekanwe. USB4 yateguwe hamwe na tunel kugirango dufatanye kohereza amakuru muri protocole nyinshi kumurongo umwe wumubiri. Rero, umuvuduko nubushobozi bwa USB4 birashobora gusaranganywa muburyo bukomeye. USB4 irashobora gushigikira iyindi protocole cyangwa itumanaho-ryakira mugihe itumanaho ryamakuru rikomeje. Byongeye kandi, USB4 yongereye umuvuduko w'itumanaho kuva 20 Gbps (Gen2x2) ya USB 3.2 kugeza40 Gbps (Gen3x2)kumurongo umwe wuburyo bumwe, bubiri-bworoshye bwubatswe.
USB4 ntabwo igera kuri USB yihuta cyane (ishingiye kuri USB3), ariko inasobanura tunel zerekana zishingiye kuri DisplayPort hamwe nu mutwaro / ububiko bwa tuneli bushingiye kuri PCIe.
Erekana icyerekezo: Kwerekana tunnel protocole ya USB4 ishingiye kuri DisplayPort 1.4a. DP 1.4a ubwayo irashyigikira8k kuri 60Hz or 4k kuri 120Hz. USB4 host ikeneye gushyigikira DisplayPort kumyambu yose yo hepfo. Niba ukoresheje icyambu cya USB 4 kugirango wohereze icyarimwe amashusho namakuru, icyambu kizagenera umurongo mugari. Kubwibyo, niba videwo isaba gusa 20% yumurongo mugari kugirango utware monitor ya 1080p (nayo ni ihuriro), noneho 80% ya videwo isigaye irashobora gukoreshwa kugirango wohereze dosiye muri SSD yo hanze.
Kubijyanye na tuneli ya PCIe: Inkunga ya PCIe na USB4 host irahitamo. USB4 hub igomba gushyigikira tuneli ya PCIe kandi PCIe yimbere igomba kuba ihari.
Igice cyingenzi cyibisobanuro bya USB 4 nubushobozi bwo guhindura byimazeyo umutungo waboneka mugihe wohereje amashusho namakuru binyuze mumurongo umwe. Noneho, tuvuge ko ufite ntarengwa40 Gbps USB 4kandi barimo gukoporora dosiye nini kuva SSD yo hanze no gusohoka kuri 4K yerekana. Dufate ko isoko ya videwo isaba hafi 12.5 Gbps. Muri iki gihe, USB 4 izagenera 27.5 Mbps isigaye kuri backup Drive.
USB-C itangiza "ubundi buryo", nubushobozi bwo kohereza amashusho ya DisplayPort / HDMI kuva ku cyambu-C. Ariko, ibyerekanwe 3.x ntabwo bitanga uburyo bwiza bwo kugabana umutungo. Nk’uko Saunders ibivuga, uburyo bwa DisplayPort bushobora kugabanya neza umurongo wa interineti hagati yamakuru ya USB namakuru ya videwo muri 50/50, mugihe uburyo bwa altMM butemerera gukoresha icyarimwe amakuru ya USB.
USB4 isobanura igipimo cya 40Gbps, igafasha kugabana imbaraga z'umuyoboro mugari kugirango umugozi umwe wamakuru ushobora kuzuza imirimo myinshi. Hamwe na USB4, birashoboka kohereza icyarimwe PCIe no kwerekana amakuru kumurongo umwe, hamwe nibikorwa gakondo bya USB, ndetse no gutanga imbaraga (ukoresheje USB PD) muburyo bworoshye. Mugihe kizaza, ibikoresho byinshi bya peripheri, byaba imiyoboro yihuta, amakarita yubushushanyo yo hanze, ibisobanuro bihanitse byerekana, ibikoresho binini byo kubika byihuse, cyangwa imashini imwe nindi mashini, birashobora guhuzwa binyuze muburyo bwa Type-C. Byongeye kandi, niba ibyo bikoresho bishyira mubikorwa USB4 Hub, urashobora kandi guhuza ibikoresho byinshi murukurikirane cyangwa amashami avuye muribi bikoresho, biroroshye cyane.
Igihe cyo kohereza: Ukwakira-20-2025
