USB 3.2 Ibyingenzi (Igice cya 1)

USB 3.2 Ibyingenzi (Igice cya 1)

Ukurikije amasezerano ya USB yo kwita amazina avuye muri USB-IF, umwimerere USB 3.0 na USB 3.1 ntuzongera gukoreshwa. Ibipimo byose USB 3.0 bizitwa USB 3.2. Ubusanzwe USB 3.2 ikubiyemo USB yose ya kera 3.0 / 3.1. Imigaragarire ya USB 3.1 ubu yitwa USB 3.2 Itangiriro 2, mugihe USB yumwimerere USB 3.0 yitwa USB 3.2 Itangiriro 1. Urebye guhuza, umuvuduko wo kohereza 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 Itangiriro 1 na USB 3.0 birashobora kumvikana nkikintu kimwe, gusa namazina atandukanye. Itangiriro 1 na Itangiriro 2 bivuga uburyo butandukanye bwo gukoresha kodegisi hamwe nigipimo cyo gukoresha umurongo mugari, mugihe Itangiriro 1 na Itangiriro 1 × 2 bitandukanye cyane muburyo bwimiyoboro. Kugeza ubu, ibibaho byinshi byo murwego rwohejuru bifite USB 3.2 Itangiriro 2 × 2, bimwe muribi Type-C nibindi bimwe USB. Kugeza ubu, Ubwoko-C Imigaragarire irasanzwe.Itandukaniro riri hagati ya Gen1, Gen2 na Gen3

1. Umuyoboro mugari: Umuyoboro ntarengwa wa USB 3.2 ni 20 Gbps, naho uwa USB 4 ni 40 Gbps.

2. Mugihe USB 4 ikubiyemo protocole ya USB 3.2, DP na PCIe mumapaki yamakuru ukoresheje tekinoroji ya tunnel ikohereza icyarimwe.
3. Ikwirakwizwa rya DP: Byombi birashobora gushyigikira DP 1.4. USB 3.2 igena ibisohoka binyuze muri DP Alt Mode (ubundi buryo); mugihe USB 4 idashobora gusa gusohora ibyasohotse binyuze muri DP Alt Mode (ubundi buryo), ariko kandi irashobora gukuramo amakuru ya DP mugukuramo paki yamakuru ya protocole ya USB4.
4. Gukwirakwiza PCIe: USB 3.2 ntabwo ishigikira PCIe, mugihe USB 4 ibikora. Amakuru ya PCIe yakuwe muri USB4 tunnel protocole yamakuru.
5. Kwanduza TBT3: USB 3.2 ntabwo ishigikira, ariko USB 4 irabikora. Binyuze muri USB4 tunnel protocole yamakuru yamapaki niho hakurwa amakuru ya PCIe na DP.
6. Abashitsi kubakira: Itumanaho hagati yabakiriye. USB 3.2 ntabwo ishyigikiye, ariko USB 4 irabishyigikiye. Impamvu nyamukuru yabyo nuko USB 4 ishyigikira protocole ya PCIe kugirango ishyigikire iki gikorwa.

Icyitonderwa: Tekinoroji ya tekinoroji irashobora gufatwa nkubuhanga bwo guhuza amakuru kuva protocole zitandukanye hamwe, hamwe nubwoko butandukanye binyuze mumapaki yamakuru.
Muri USB 3.2, ihererekanyabubasha rya videwo ya DisplayPort na USB 3.2 bibaho binyuze mumashanyarazi atandukanye, mugihe muri USB 4, Video ya DisplayPort, USB 3.2, hamwe na PCIe bishobora koherezwa binyuze kumuyoboro umwe. Iri ni ryo tandukaniro rinini hagati yombi. Urashobora kwifashisha igishushanyo gikurikira kugirango ubashe gusobanukirwa byimbitse.

Umuyoboro wa USB4 urashobora gutekerezwa nkumuhanda wemerera ibinyabiziga bitandukanye kunyuramo. USB amakuru, amakuru ya DP, hamwe na PCIe birashobora gufatwa nkibinyabiziga bitandukanye. Mu murongo umwe, ibinyabiziga bitandukanye biri ku murongo kandi bigenda neza kuri gahunda. Umuyoboro umwe wa USB4 wohereza ubwoko butandukanye bwamakuru muburyo bumwe. USB3.2, DP, na PCIe byabanje guhurira hamwe hanyuma byoherezwa binyuze mumurongo umwe kubindi bikoresho, hanyuma ubwoko butatu bwamakuru butandukanye.
