Ixesha logqithiso lwesantya esiphezulu luyeza-i-USB 4.0
Intshayelelo
Ngowe-1994, i-Intel kunye ne-Microsoft yaqalisa i-International Standardization Organisation, ebizwa ngokuba yi "USB-IF". Umbutho uphuhlise uluhlu lweenkcukacha kunye neenkcukacha zebhasi ye-universal serial bus. Phakathi kwazo, umgangatho ophuhliswe ngokujikeleza intlawulo ekhawulezayo yi-USB PD protocol eyaziwayo, okwangoku iyenye yezona ndlela zisebenza kakhulu zokutshaja kuluntu, kwaye ingxelo yophando malunga ne-industrial ecology yePD 3.1 ikhutshiwe phambi kwentloko yokutshaja. inethiwekhi ikhuphe umbhalo omde, umntu unokuqonda lonke ikhonkco loshishino lwePD 3.1.
Ukongeza, i-USB-IF iphuhlise umgangatho wokuhanjiswa kwedatha, kwaye yabizwa ngokuthe ngqo i-USB #.0, emva kotshintsho lwenguqulelo yangoku, inkcazo yamva nje ye-USB yi-USB4, eli nqaku liza kungena kwi-USB4 ukusukela ekukhululweni kwayo, kwimarike. ukwakha i-ikholoji yoshishino.
Malunga USB4
Iprotocol yokudlulisa idatha ye-USB yakhululwa ngaphambili kakhulu kune-USB PD, kwaye i-USB1.0 yaziswa ngo-1996, unyaka wesithathu emva kokuba i-USB-IF isekiwe. Isizukulwana sokuqala somgangatho we-USB, izinga losulelo lwayo yi-1.5Mbps kuphela, iinkcukacha zophuhliso lweenguqulelo zembali ye-USB nceda ubone le theyibhile ilandelayo:
NgoSeptemba ka-2019, i-USB4 yakhululwa ngokusemthethweni ngesantya esiphezulu sothumelo lwe-40Gbps, efanayo neThunderbolt 3. I-USB4 ineenkcukacha ezimbini, ngokulandelelana, i-USB4 40 enomthamo omkhulu we-40Gbps, i-USB4 20 ene-bandwidth ephezulu ye-20Gbps, kwaye abathengi bayayidinga. ukuqonda ukuba i-USB4 40 lujongano olupheleleyo lwegazi.
NgoSeptemba ka-2022, umgangatho we-USB4 2.0 wavezwa kwangaphambili, umlinganiselo ophezulu wonyuswa ukuya kwi-80Gbps, ulwakhiwo olutsha lwedatha lwamkelwa, kunye nomgangatho wokutshaja okhawulezayo we-USB PD, ujongano lwe-USB Type-C kunye nomgangatho wentambo nazo ziya kuhlaziywa ngokuhambelanayo.
Ingabonwa ukuba kwinkqubo yokuhlaziywa kwenguqulo, utshintsho olukhulu luphuculo lwezinga lokudluliselwa kwedatha, ukusuka kwi-1.5Mbps yokuqala ukuya kwi-exposure yangoku ye-USB4 2.0 ifikelele kwi-80Gbps, ukwanda kwamashumi amawaka amaxesha. Olu tshintsho lubangelwa ikakhulu kuphuculo lwejelo losasazo lwedatha, ukusukela ngo-2013, inguqulelo ye-USB3 yochungechunge, yanda ukuya kwi-4 izibini zamatshaneli ahlukeneyo, kwaye ixhotyiswe ukusebenza kakuhle kwe-USB-C port, ukwenza ukuhanjiswa kwedatha kunokuphuculwa komgangatho.
Okwangoku, zininzi iimveliso ezisebenzisa umsebenzi wothumelo lwedatha olukwisantya esiphezulu se-USB-C ujongano, ikakhulu ezinye izixhobo zokugcina zangaphandle (ezinje ngesantya esiphezulu sokuqhuba okuqinileyo, iintambo zothumelo olukwisantya esiphezulu, kunye nojongano olusetyenziswa ngokuthe ngqo ezinye iincwadana ezikumgangatho ophezulu).
