Isithangami Sokuqalisa se-USB (USB-IF), ibhizinisi elisekela futhi likhuthaze ukwamukelwa kwamazinga obuchwepheshe be-USB (noma i-Universal Serial Bus), muva nje umemezele ukuphothulwa kwezinga le-USB 4 futhi yaqinisekisa ukuthi isilungele ukuthunyelwa okukhulu.
Kuze kube manje, Sekukhishwe imininingwane ye-USB 4, okuveza ukuthi ubuchwepheshe buncike kakhulu esicacisweni seThunderbolt yakamuva (inguqulo 3) futhi ithembisa amazinga aphezulu wedatha (angafika kuma-40 Gb / s). Izinga le-USB 4 lisizakala ngesixhumi esijwayelekile se-USB-C futhi ibuyela emuva iyahambisana namazinga we-USB wangaphambilini, kufaka phakathi i-USB 3.2 ephinda kabili isivinini esiphezulu soxhumano lwe-USB (kusuka ku-10 Gb / s kuye ku-20 Gb / s), i-USB 2.0 neThunderbolt 3.
UBrad Saunders, isikhulu esiphezulu se-USB Promoter Group, uthe inhlangano yakhe ifuna nje ukugcina izinto zilula nokugwema ukutholakala kwemikhiqizo enezinombolo zezinhlobo ezingadida abathengi.
Nge-USB 4, asizimisele ukuhamba ngomkhondo we-4.0, 4.1, 4.2, "echaza," sifuna ukuyigcina ilula ngangokunokwenzeka.
Kusukela ngo-2007, i-Intel ihlanganyele ngokuhlanganyela isikhombimsebenzisi seThunderbolt ne-Apple, esenzelwe ukuhlanganisa ukuxhumana kwekhompyutha.
Iteration yesithathu o I-Thunderbolt 3 yethulwe ngo-2015 futhi inikezela ngejubane lama-40 Gb / s . Ukuxhumana phakathi kweThunderbolt ne-USB bekungaqagelwa, ngoba inguqulo 3, iThunderbolt isebenza nge-USB-C, ngakho itheku leThunderbolt 3 lingamukela amadivayisi we-USB 3.
Izinga le-USB 3 lethule ikhono lokusebenzisa ikhebuli elilodwa ukushaja amanye amadivayisi, dlulisa idatha nesiginali yevidiyo. Kepha kwesinye isikhathi, ngokuya ngokucushwa kwakho, bekwenzeka ukwenza umsebenzi owodwa kuphela futhi ngejubane eliphansi kakhulu.
Izinga elisha le-USB 4 lithembisa ukubhekana nalokhu ngokunikeza umsingathi amandla wokukala ngokulinganayo ukwabiwa kokuhamba kwedatha nokuboniswa.
I-USB 4 ivumela izibonisi ezingama-4K noma eziyi-8K ukuthi zixhunywe kwi-USB, ku-chain ye-daisy inani lamadivayisi we-USB ahlanganisiwe ethekwini elifanayo futhi isekela ukufakwa kwamandla kwamadivayisi abonisa amandla amakhulu wama-watts ayi-100 ngokusebenza kokulethwa kwamandla.
I-USB 4 kufanele futhi ixhunywe kuphela kusixhumi se-USB Type-C ngezikhonkwane ezingamashumi amabili nane (esikhundleni sezine noma eziyisishiyagalolunye njengakwizinguqulo zangaphambilini ze-USB).
Ezinye izici ezibalulekile zesisombululo se-USB 4 zifaka phakathi:
- Ukusebenza kwemizila emibili kusetshenziswa izintambo ezikhona ze-USB Type-C nokusebenza okungafika ku-40 Gbps ngaphezulu kwezintambo eziqinisekisiwe ezingama-40 Gbps
- Idatha eminingi kanye nezivumelwano zokubonisa ngokuhlanganyela kahle zabelana ngomkhawulokudonsa ohlanganisiwe omkhulu
- Ukuhambisana okubuyela emuva kwe-USB 3.2, i-USB 2.0, ne-Thunderbolt 3
Inzuzo yangempela Ukucaciswa kwe-USB 4 ukuthi ukuxhumana okukhona kwe-USB Type-C kuzokwazi ukuphatha ukusakazwa kwedatha okuphezulu kakhulu, kanye nesiteshi sokuxhumana sesibili.
Akugcini lapho, kepha amandla okushayela amadivayisi weThunderbolt 3 nawo aletha izinzuzo kubuchwepheshe befa leThunderbolt, elisebenza kahle ngokuphelele.
Kuyafana kakhulu lapho ucabanga ngalokho abaklami beCFExpress abakutholile ngokwandisa ukucaciswa kwe-XQD okukhona ukuze abasebenzisi bakwazi ukuqhubeka nokusebenzisa amadivayisi abo nge-firmware elula.
Ukwenza lula ukwamukelwa kwaleli zinga elisha, I-Intel iqinisekise ukuthi isizukulwane sayo esilandelayo sama-processor we-x86, ukuqala e-Ice Lake, izosekela i-USB 4 ngokwendabuko futhi ukhombise inhloso yakho yokukhipha imininingwane yeThunderbolt 3 ngokugunyaza ukusetshenziswa kwalobu buchwepheshe ngaphandle kwezindleko.
Amadivayisi okuqala ahambisana ne-USB 4 akufanele afike ngaphambi kuka-2020 okungcono kakhulu futhi kuzodinga ukuthi kusetshenziswe i-adaptha ethengiswe ngokuhlukile ukusebenzisa ngokugcwele amandla echweba le-USB 4.
Futhi okuyingxenye enhle kakhulu ukuthi abasebenzisi abagweme ukukhokha amanani aphakeme wejubane leThunderbolt 3 ngeke nje bavuzwe ngohlobo olungabizi kakhulu, kepha bazokwazi ukwenza kanjalo besebenzisa ukuxhumana okukhona kohlobo lwe-C kokusebenza okuphezulu okufanayo. inzuzo okufanele ilethe i-USB 4 esikhathini esizayo esingu-8K.
I-USB-IF ihlela ukuqeqeshwa kwezobuchwepheshe kule ncazelo phakathi Nezinsuku Zonjiniyela be-USB ngokuhamba kwesikhathi kule nyanga eSeattle nasekupheleni kukaNovemba eTaipei, eTaiwan.
