Ibintu by'ibanze bya USB 3.2 (Igice cya 1)

Dukurikije uburyo bushya bwo kwita amazina ya USB muri USB-IF, USB 3.0 na USB 3.1 bya mbere ntibizongera gukoreshwa. Ibipimo byose bya USB 3.0 bizitwa USB 3.2. Ibipimo bya USB 3.2 bikubiyemo imiyoboro yose ya kera ya USB 3.0/3.1. Imiyoboro ya USB 3.1 ubu yitwa USB 3.2 Gen 2, mu gihe imiyoboro ya mbere ya USB 3.0 yitwa USB 3.2 Gen 1. Ukurikije uburyo bwo guhuza, umuvuduko wo kohereza wa USB 3.2 Gen 1 ni 5Gbps, USB 3.2 Gen 2 ni 10Gbps, na USB 3.2 Gen 2 × 2 ni 20Gbps. Kubwibyo, ibisobanuro bishya bya USB 3.1 Gen 1 na USB 3.0 bishobora kumvikana nk'ikintu kimwe, hamwe n'amazina atandukanye. Gen 1 na Gen 2 bivuga uburyo butandukanye bwo gukodesha no gukoresha umuvuduko wa bandwidth, mu gihe Gen 1 na Gen 1 × 2 bitandukanye mu buryo bw'inyuguti. Muri iki gihe, motherboard nyinshi zo mu rwego rwo hejuru zifite imiyoboro ya USB 3.2 Gen 2×2, zimwe muri zo zikaba ari imiyoboro ya Type-C izindi zikaba ari imiyoboro ya USB. Muri iki gihe, imiyoboro ya Type-C irakunze kugaragara. Itandukaniro riri hagati ya Gen1, Gen2 na Gen3

1. Umuyoboro wa transmission: Umuyoboro ntarengwa wa USB 3.2 ni 20 Gbps, mu gihe uwa USB 4 ari 40 Gbps.

2. Porotokole yo kohereza amakuru: USB 3.2 yohereza amakuru cyane cyane binyuze muri porotokole ya USB, cyangwa igashyiraho USB na DP binyuze muri DP Alt Mode (uburyo bundi). Mu gihe USB 4 ishyiramo porotokole za USB 3.2, DP na PCIe mu mapaki y'amakuru hakoreshejwe ikoranabuhanga rya tunnel hanyuma ikabyohereza icyarimwe.
3. Kohereza DP: Byombi bishobora gushyigikira DP 1.4. USB 3.2 igena umusaruro unyuze muri DP Alt Mode (uburyo busimbura ubundi); mu gihe USB 4 idashobora gusa gushyiraho umusaruro unyuze muri DP Alt Mode (uburyo busimbura ubundi), ahubwo inashobora gukuramo amakuru ya DP ikoresheje paki z'amakuru za protocole ya USB4.
4. Kohereza amakuru kuri PCIe: USB 3.2 ntishyigikira PCIe, mu gihe USB 4 ishyigikira. Amakuru ya PCIe akurwa binyuze mu mapaki y'amakuru ya protocole ya USB4.
5. Kohereza amakuru kuri TBT3: USB 3.2 ntabwo ishyigikira, ariko USB 4 ishyigikira. Ni binyuze mu mapaki y'amakuru ya protocole ya USB4 aho amakuru ya PCIe na DP akurwa.
6. Host to Host: Itumanaho hagati ya hosts. USB 3.2 ntabwo ishyigikira, ariko USB 4 ishyigikira. Impamvu nyamukuru ibi ni uko USB 4 ishyigikira protocole ya PCIe kugira ngo ishyigikire iyi mikorere.

Icyitonderwa: Ikoranabuhanga ryo gukurura amakuru mu buryo bw'ikoranabuhanga rishobora gufatwa nk'uburyo bwo guhuza amakuru aturutse kuri protocole zitandukanye hamwe, ubwoko bugatandukanywa binyuze mu mutwe w'amakuru.
Muri USB 3.2, kohereza amakuru ya DisplayPort videwo na USB 3.2 bibaho binyuze mu ma adaptateri atandukanye, mu gihe muri USB 4, amakuru ya DisplayPort videwo, USB 3.2, na PCIe bishobora koherezwa binyuze mu muyoboro umwe. Iri ni ryo tandukaniro rikomeye hagati y’ibyo byombi. Ushobora kureba igishushanyo gikurikira kugira ngo usobanukirwe byimbitse.

Umuyoboro wa USB4 ushobora gufatwa nk'inzira yemerera ubwoko butandukanye bw'imodoka kunyuramo. Amakuru ya USB, amakuru ya DP, n'amakuru ya PCIe bishobora gufatwa nk'imodoka zitandukanye. Mu nzira imwe, imodoka zitandukanye zitondetse kandi zigenda mu buryo bunoze. Umuyoboro umwe wa USB4 wohereza ubwoko butandukanye bw'amakuru mu buryo bumwe. Amakuru ya USB3.2, DP, na PCIe abanza guhuzwa hamwe maze yoherezwa binyuze muri uwo muyoboro umwe ku kindi gikoresho, hanyuma ubwoko butatu butandukanye bw'amakuru buratandukana.
