I-USB4 2.0 isiyatholakala konjiniyela futhi ithembisa ukuthuthukiswa kwesivinini esikhulu sokudlulisa
Esikhathini esingeside esidlule, kumenyezelwe ukukhishwa kwesicaciso esisha se-USB 4.0, i-Linux esivele yamukele ngokuyihlanganisa ku-kernel eyinhloko futhi ukusekelwa kwayo sekukhona izinyanga ezimbalwa manje.
Futhi manje, kukhishwe izindaba zokuthi iyasebenza vele isesibuyekezweni (USB4) ini izovumela ukusebenza okufika ku-80 Gb/s, ngokusekelwe esakhiweni esisha sesendlalelo esibonakalayo, kusetshenziswa amakhebuli akhona angu-40 Gbps e-USB Type-C kanye namakhebuli asebenzayo angu-80 Gbps e-USB Type-C asanda kuchazwa.
KwakungoSepthemba 2019 lapho kwamenyezelwa khona inguqulo yokuqala ye-USB 4 nokuthi lokhu ithembele kakhulu ku-Thunderbolt 3 standard futhi inikeza isivinini esifanayo esiphezulu (kufika ku-40 Gb/s).
I-USB4 1.0 ikuvumela ukuthi uxhume izibonisi ze-4K noma ze-8K nge-USB, xhuma uchungechunge lwama-peripheral e-USB ahlukahlukene embotsheni efanayo, phakathi kwezinye izici.
Eminyakeni emithathu kamuva, sekuyisikhathi sokuba inguqulo 2.0 yezinga le-USB4 lenzeke. Ukucaciswa kwangempela kobuchwepheshe kwe- Iforamu yabaSebenzi be-USB, lokho unesibopho sezinga ngokwayo, ayikashicilelwa okwamanje, kodwa imininingwane eshicilelwe iyamangaza kancane.
Iqembu Lomgqugquzeli we-USB ithi ihlela ukukhipha indinganiso entsha ye-USB4 2.0 ngaphambi kwemicimbi ye-USB Developer Days 2022, okuhlelelwe u-November, kodwa kungase kuthathe iminyaka embalwa ngaphambi kokuba amakhebuli amasha, amahabhu, ama-PC namadivayisi eselula afakwe lobu buchwepheshe obusha atholakale emphakathini.
I-USB Promoter Group, ehlanganisa i-Apple, i-Microsoft, i-Intel, i-HP, i-STM nezinye, imemezele esitatimendeni sabezindaba ukuthi izintambo ze-USB4 2.0 zizosebenzisa isixhumi se-USB-C, njengoba bekulindelekile. Kodwa izindaba ezigqama kakhulu yilezi:
"I-USB4 2.0 izonika amandla ukusebenza okungafika ku-80Gb/s, ngokusekelwe ekwakhiweni kwesendlalelo esisha esibonakalayo, kusetshenziswa i-40Gb/s ekhona kanye nezintambo ezisanda kuchazwa ze-80Gb/s USB Type-C." s Amakhebuli e-USB Type-C asebenzayo”. Izicaciso ze-USB-C kanye ne-USB Power Delivery zizobuyekezwa ukuze kunikwe amandla ileveli elandelayo yokudlulisa idatha.
Izinga elisha lizophinde lithule ikhebula elisha le-USB-C elisebenzayo elakhelwe ngokuqondile isivinini esifika ku-80 Gbps. Izibuyekezo ziyaqhubeka ukuze kuvunyelwe ukusebenza okuphezulu kwe-USB 3.2, i-DisplayPort, ne-PCIe ukushuna idatha ukuze kuzuze kangcono umkhawulokudonsa okhuphukile.
Nasi isifinyezo sezici eyaziwa kuze kube manje:
- kufika ku-80 Gb/s ukusebenza, kusetshenziswa izintambo ezikhona ze-USB-C ezingu-40 Gbps kanye nezintambo ezisebenzayo ezingu-80 Gbps ze-USB-C
- ukubuyekezwa kwedatha kanye nemigomo yokubonisa ukusebenzisa kangcono umkhawulokudonsa otholakalayo owandile
- Izibuyekezo zokwakheka kwedatha ye-USB manje zivumela i-USB 3.2 ukuthi yeqe u-20 Gb/s
- ibuyekeziwe ukuze ihambisane nezinguqulo zakamuva ze-DisplayPort kanye ne-PCIe ecacisiwe
- ukuhambisana emuva ne-USB4 1.0, i-USB 3.2, i-USB 2.0 ne-Thunderbolt 3.
Kusukela kulokhu kucaciswa, kufanele kuqashelwe ukuthi i-80 Gbps inamandla amaningi, kodwa ukucaciswa akuklanyelwe ukuzinikela ngokuphelele ekuxhumekeni okukodwa. Kunalokho, ihloselwe ukusabalalisa ama-80 Gb/s phakathi kwamadivayisi ahlukene exhunywe kuhabhu noma esiteshini sedokhi.
Ngokuqondene negama, kungase kubonakale kungavamile ukulebula lo mkhiqizo ngokuthi nje "inguqulo 2.0" ye-USB4, lapho ukukhuphuka kwesivinini kubonakala kuthethelela igama elithi USB5. Nokho, izinga liye ladida iminyaka embalwa manje.
I-USB 3.2 empeleni ingamazinga amaningana ahlukene: I-USB 3.2 Gen 1 (ebuye yaziwe ngokuthi i-USB 3.0 yasekuqaleni), i-USB 3.2 Gen 2, i-USB 3.2 Gen 1x2, ne-USB 3.2 Gen 2x2 (okuyindlela ephelele engu-20Gb) . I-USB4 igcine izinto zilula njengoba ngokuyisisekelo yayinama-specs namakhono afanayo njenge-Thunderbolt 3.
Ekugcineni kufanelekile ukusho lokho ekukhishweni kwabezindaba okunikezwe i-USB Promotor Group, bakusho lokho isibuyekezo "senzelwe onjiniyela ngokukhethekile ngalesi sikhathi", nokuthi imihlahlandlela yokugcina yokumaketha (kuhlanganise nezinto ezifana namalogo) izofika kamuva. Kumazwana, siyabona ukuthi abaningi baphelelwa isineke ngombono wokukwazi ukudlulisa okulingana ne-4K Blu-ray cishe imizuzwana emihlanu.
Iqembu akazange anikeze imininingwane egcwele ngezinga elisha, kodwa uthe izobuyela emuva ihambisane namazinga e-USB4 1.0, USB 3.2, USB 2.0 kanye neThunderbolt 3.
Uma unesifiso sokwazi okwengeziwe ngakho, ungaxhumana nemininingwane Kulesi sixhumanisi esilandelayo.
