Ngā Kaupapa Taketake o te USB 3.2 (Wāhanga 1)

E ai ki te tikanga whakaingoa USB hou mai i te USB-IF, kāore e whakamahia te USB 3.0 me te USB 3.1 taketake. Ka kiia ngā paerewa USB 3.0 katoa ko te USB 3.2. Kei roto i te paerewa USB 3.2 ngā atanga USB 3.0/3.1 tawhito katoa. Ko te atanga USB 3.1 e kiia nei ko te USB 3.2 Gen 2, ko te atanga USB 3.0 taketake ia ko te USB 3.2 Gen 1. Ina whakaarohia te hototahitanga, ko te tere whakawhiti o te USB 3.2 Gen 1 he 5Gbps, ko te USB 3.2 Gen 2 he 10Gbps, ā, ko te USB 3.2 Gen 2×2 he 20Gbps. Nō reira, ka taea te mārama ko te whakamāramatanga hou o te USB 3.1 Gen 1 me te USB 3.0 he mea kotahi, engari he rerekē ngā ingoa. Ko te Gen 1 me te Gen 2 e pā ana ki ngā tikanga whakawaehere rerekē me ngā reiti whakamahinga whānui, ko te Gen 1 me te Gen 1×2 he rerekē te āhua o ngā hongere. I tēnei wā, he maha ngā papahoahoa papai kei a rātou ngā atanga USB 3.2 Gen 2×2, ko ētahi he atanga Momo-C, ko ētahi he atanga USB. I tēnei wā, he mea noa ake ngā atanga Momo-C. Ko ngā rerekētanga i waenga i te Gen1, Gen2 me te Gen3

1. Te whānui o te tuku raraunga: Ko te whānui mōrahi o te USB 3.2 he 20 Gbps, ko te USB 4 ia he 40 Gbps.

2. Kawa tuku: Ko te tikanga matua o te USB 3.2 ko te tuku raraunga mā te kawa USB, ko te whirihora rānei i te USB me te DP mā te Aratau DP Alt (aratau rerekē). Ahakoa ko te USB 4 ka whakakotahi i ngā kawa USB 3.2, DP me te PCIe ki roto i ngā mōkihi raraunga mā te whakamahi i te hangarau kauhanga, ā, ka tukuna ngātahitia.
3. Tuku DP: Ka taea e ngā mea e rua te tautoko i te DP 1.4. Ka whirihorahia e te USB 3.2 te putanga mā te Aratau Alt DP (aratau rerekē); i te mea kāore e taea e te USB 4 te whirihora i te putanga mā te Aratau Alt DP (aratau rerekē), engari ka taea hoki te tango raraunga DP mā te tango i ngā mōkihi raraunga o te kawa kauhanga USB4.
4. Tukunga PCIe: Kāore te USB 3.2 e tautoko i te PCIe, engari ko te USB 4 e tautoko ana. Ka tangohia ngā raraunga PCIe mā roto i ngā mōkihi raraunga o te kawa kauhanga USB4.
5. Tukunga TBT3: Kāore e tautokona e te USB 3.2, engari e tautokona ana e te USB 4. Mā roto i ngā mōkihi raraunga o te kawa kauhanga USB4 ka tangohia ngā raraunga PCIe me DP.
6. Kaihautū ki te Kaihautū: Te whakawhitiwhiti kōrero i waenga i ngā kaihautū. Kāore a USB 3.2 e tautoko, engari e tautoko ana a USB 4. Ko te take matua mō tēnei he tautoko a USB 4 i te kawa PCIe hei tautoko i tēnei mahi.

Kia mōhio: Ka taea te kī ko te hangarau whakapūtanga he tikanga mō te whakauru i ngā raraunga mai i ngā kawa rerekē, me te momo e wehewehea ana mā te pane mōkihi raraunga.
I roto i te USB 3.2, ka tukuna ngā raraunga ataata DisplayPort me te USB 3.2 mā roto i ngā hononga hongere rerekē, engari i roto i te USB 4, ka taea te tuku raraunga ataata DisplayPort, USB 3.2, me te PCIe mā roto i te hongere kotahi. Koinei te rerekētanga nui i waenganui i ngā mea e rua. Ka taea e koe te tirotiro i te hoahoa e whai ake nei kia mārama ake ai.

Ka taea te whakaaro i te hongere USB4 hei ara e taea ai e ngā momo waka te haere. Ka taea te whakaaro ko ngā raraunga USB, ngā raraunga DP, me ngā raraunga PCIe he waka rerekē. I te ara kotahi, ka whakarārangihia ngā waka rerekē, ka haere i runga i te tikanga tika. Ka tukuna e te hongere USB4 kotahi ngā momo raraunga rerekē i te ara kotahi. Ka tūtaki tuatahi ngā raraunga USB3.2, DP, me PCIe, ka tukuna atu mā te hongere kotahi ki tētahi atu pūrere, kātahi ka wehea ngā momo raraunga e toru.
