Abubuwan Da Ya Kamata Na USB 3.2 (Kashi Na 1)

A bisa sabon tsarin sanya suna na USB daga USB-IF, ba za a sake amfani da asalin USB 3.0 da USB 3.1 ba. Duk ƙa'idodin USB 3.0 za a kira su da USB 3.2. Ma'aunin USB 3.2 ya haɗa da duk tsoffin hanyoyin haɗin USB 3.0/3.1. Ana kiran hanyar haɗin USB 3.1 yanzu USB 3.2 Gen 2, yayin da asalin hanyar haɗin USB 3.0 ana kiranta USB 3.2 Gen 1. Idan aka yi la'akari da dacewa, saurin canja wurin USB 3.2 Gen 1 shine 5Gbps, USB 3.2 Gen 2 shine 10Gbps, kuma USB 3.2 Gen 2 × 2 shine 20Gbps. Saboda haka, sabon ma'anar USB 3.1 Gen 1 da USB 3.0 za a iya fahimtar su a matsayin abu ɗaya, kawai tare da sunaye daban-daban. Gen 1 da Gen 2 suna nufin hanyoyin ɓoyewa daban-daban da ƙimar amfani da bandwidth, yayin da Gen 1 da Gen 1 × 2 sun bambanta sosai dangane da tashoshi. A halin yanzu, yawancin manyan motherboards suna da kebul na USB 3.2 Gen 2×2, wasu daga cikinsu kebul na Type-C ne wasu kuma kebul na USB ne. A halin yanzu, kebul na Type-C ya fi yawa. Bambance-bambance tsakanin Gen1, Gen2 da Gen3

1. Babbawar watsawa: Matsakaicin babbawar USB 3.2 shine 20 Gbps, yayin da na USB 4 shine 40 Gbps.

2. Tsarin watsawa: USB 3.2 galibi yana watsa bayanai ta hanyar tsarin USB, ko kuma yana saita USB da DP ta hanyar Yanayin DP Alt (madadin yanayin). Yayin da USB 4 ke haɗa ka'idojin USB 3.2, DP da PCIe zuwa fakitin bayanai ta amfani da fasahar rami kuma yana aika su a lokaci guda.
3. Watsawar DP: Dukansu za su iya tallafawa DP 1.4. USB 3.2 yana saita fitarwa ta hanyar Yanayin DP Alt (madadin yanayin); yayin da USB 4 ba wai kawai zai iya saita fitarwa ta hanyar Yanayin DP Alt (madadin yanayin ba), har ma zai iya cire bayanan DP ta hanyar cire fakitin bayanai na yarjejeniyar ramin USB4.
4. Watsawar PCIe: USB 3.2 baya goyon bayan PCIe, yayin da USB 4 ke goyon bayan. Ana cire bayanan PCIe ta hanyar fakitin bayanai na yarjejeniyar USB4.
5. Watsawa ta TBT3: USB 3.2 ba ya goyan bayansa, amma USB 4 yana goyan bayansa. Ta hanyar fakitin bayanai na yarjejeniyar USB4 ne ake fitar da bayanan PCIe da DP.
6. Mai watsa shiri zuwa mai watsa shiri: Sadarwa tsakanin masu watsa shiri. USB 3.2 ba ya goyan baya, amma USB 4 yana goyan baya. Babban dalilin hakan shine USB 4 yana goyan bayan yarjejeniyar PCIe don tallafawa wannan aikin.

Lura: Ana iya ɗaukar fasahar tunneling a matsayin dabarar haɗa bayanai daga ka'idoji daban-daban tare, tare da nau'in da aka bambanta ta hanyar kanun fakitin bayanai.
A cikin USB 3.2, watsa bidiyon DisplayPort da bayanai na USB 3.2 yana faruwa ta hanyar adaftar tashoshi daban-daban, yayin da a cikin USB 4, bidiyon DisplayPort, bayanai na USB 3.2, da bayanai na PCIe za a iya watsa su ta hanyar tashar guda ɗaya. Wannan shine babban bambanci tsakanin su biyun. Kuna iya komawa zuwa zane mai zuwa don samun fahimta mai zurfi.

Ana iya tunanin tashar USB4 a matsayin layi wanda ke ba da damar nau'ikan ababen hawa daban-daban su ratsa ta. Ana iya ɗaukar bayanan USB, bayanan DP, da bayanan PCIe a matsayin motoci daban-daban. A cikin layi ɗaya, ana yin layuka daban-daban kuma suna tafiya cikin tsari. Tashar USB4 iri ɗaya tana watsa nau'ikan bayanai daban-daban ta hanya ɗaya. Bayanan USB3.2, DP, da PCIe da farko suna haɗuwa kuma ana aika su ta hanyar tashar ɗaya zuwa ɗayan na'urar, sannan a raba nau'ikan bayanai guda uku daban-daban.
