IForum yokuFezekisa ye-USB (I-USB-IF), iziko elixhasa kwaye likhuthaze ukwamkelwa kwemigangatho yetekhnoloji ye-USB (okanye ye-Universal Serial Bus), Kutshanje kubhengezwe ukugqitywa komgangatho we-USB 4 kwaye yaqinisekisa ukuba ikulungele ukuthunyelwa okukhulu.
Ukuya koku kuphela, Iinkcukacha ze-USB 4 zikhutshiwe, zityhila ukuba itekhnoloji ixhomekeke kakhulu kwinkcazo yeThunderbolt yamva nje (uguqulelo 3) kwaye uthembisa amaxabiso afanayo aphezulu edatha (ukuya kuthi ga kwi-40 Gb / s). Umgangatho we-USB 4 usebenzisa ithuba lokudibanisa iklasikhi ye-USB-C kwaye ibuyela umva iyahambelana nemigangatho ye-USB, kubandakanya i-USB 3.2 ephindaphinda isantya esiphezulu soqhagamshelo lwe-USB (ukusuka kwi-10Gb / s ukuya kwi-20Gb / s), i-USB 2.0 kunye neThunderbolt 3.
UBrad Saunders, iCEO yeQela eliKhuthazayo le-USB, uthe umbutho wakhe ufuna nje ukugcina izinto zilula kwaye uphephe ukuxhaphaka kweemveliso ezinesitampu esinamanani ohlobo olunokubabhida abathengi.
Nge-USB 4, asizimiselanga kuhla ngendlela eyi-4.0, 4.1, 4.2, utshilo, "sifuna ukuyigcina ilula kangangoko.
Ukusukela ngo-2007, i-Intel ngokudibeneyo iphuhlise ujongano lweThunderbolt kunye neApple, eyilelwe ukudibanisa ikhomputha.
Iteration yesithathu o I-Thunderbolt 3 yasungulwa ngo-2015 kwaye inikezela ngesantya sama-40 Gb / s . Unxibelelwano phakathi kweThunderbolt kunye ne-USB lwalunokuxelwa kwangaphambili, kuba inguqulelo yesi-3, iThunderbolt isebenza nge-USB-C, ngenxa yoko izibuko leThunderbolt 3 linokwamkela izixhobo ze-USB 3.
Umgangatho we-USB 3 wazise amandla okusebenzisa intambo enye ukutshaja ezinye izixhobo, dlulisa idatha kunye nomqondiso wevidiyo. Kodwa ngamanye amaxesha, kuxhomekeka kuqwalaselo lwakho, kunokwenzeka ukwenza enye kuphela yale mi sebenzi kwaye ngesantya esiphantsi kakhulu.
Imigangatho emitsha ye-USB 4 ithembisa ukujongana noku ngokunika umgcini amandla okwenza ulwabiwo ngokugqibeleleyo lokuhamba kwedatha kunye nomboniso.
I-USB 4 ivumela i-4K okanye i-8K imiboniso ukuba iqhagamshelwe kwi-USB, Kwikhonkco le-daisy uthotho lwezixhobo ze-USB ezahlukileyo kwizibuko elinye kwaye ixhasa ukubanakho kwezixhobo ezibonisa amandla aphezulu e-watts ezili-100 ngokusebenza kwamandla.
I-USB 4 kufuneka iqhagamshelwe kuphela kwisinxibelelanisi sohlobo C lwe-USB Izikhonkwane ezingamashumi amabini anesine (endaweni yezine okanye ezisithoba njengakwinguqulelo zangaphambili ze-USB).
Ezinye izinto eziphambili kwisisombululo se-USB 4 zibandakanya:
- Ukusebenza kwemizila emibini usebenzisa iintambo ezikhoyo zohlobo C lwe-C ukuya kuthi ga kwi-40 Gbps yokusebenza ngaphezulu kweentambo ezingama-40 zeGbps eziqinisekisiweyo
- Iinkcukacha ezininzi kunye neeprotokholi zokubonisa ezabelana ngokufanelekileyo ngobuninzi bebhendi
- Ukubuyela umva kokuhambelana kwe-USB 3.2, i-USB 2.0, kunye neThunderbolt 3
Isibonelelo sokwenyani Ukucaciswa kwe-USB 4 Kukuba unxibelelwano lwe-C olukhoyo lwe-C luya kuba nakho ukuphatha elona data liphezulu, Kunye nejelo lonxibelelwano lesibini.
Ayisiyiyo loo nto kuphela, kodwa ukubanakho ukuqhuba izixhobo zeThunderbolt 3 zikwazisa izibonelelo kwitekhnoloji yelifa leThunderbolt, esebenza ngokugqibeleleyo.
Kuyafana kakhulu xa ucinga ngento abayili beCFExpress abayenzileyo ngokwandisa iinkcukacha zeXQD ezikhoyo ukuze abasebenzisi baqhubeke nokusebenzisa izixhobo zabo ngohlaziyo olulula lwe-firmware.
Ukulungiselela ukwamkelwa kwalo mgangatho mtsha, I-Intel iqinisekisile ukuba isizukulwana sayo esilandelayo se-x86 processorsUkuqala eIqhwa, izakuxhasa i-USB 4 Ngokwendalo kunye nokusa umqondiso kwinjongo yakho yokukhupha i-Thunderbolt 3 imigaqo ngokugunyazisa ukusetyenziswa kwasimahla kobuchwephesha.
Izixhobo zokuqala ezihambelana ne-USB 4 akufuneki zifike ngaphambi kuka-2020 okona kulungileyo kwaye kuya kufuna ukusetyenziswa kweadaptha ethengiswe yodwa ukuxhaphaza ngokupheleleyo amandla ezibuko le-USB 4.
Kwaye elona candelo lililo kukuba abasebenzisi abakuthinteleyo ukuhlawula amaxabiso aphezulu ngesantya seThunderbolt 3 abayi kuvuzwa kuphela ngenguqu efikelelekayo, kodwa baya kuba nakho ukwenza oko besebenzisa unxibelelwano olukhoyo kuhlobo C-lwentsebenzo efanayo ephezulu. Isibonelelo esikhulu ekufuneka sizise i-USB 4 kwikamva le-8K.
I-USB-IF icwangcisa uqeqesho lobuchwephesha kwinkcazo ngexesha leNtsuku zoPhuculo lwe-USB kamva kule nyanga eSeattle nasekupheleni kukaNovemba eTaipei, eTaiwan.
