Te Aratohu Tino Pai ki te USB4 Mai i te Tere 40Gbps, te Whānuitanga Hihiri ki te Hononga Taura Kotahi Mahi-Katoa
Mai i te putanga mai o te USB4, kua whakaputahia e mātou he maha ngā tuhinga me ngā hononga hei whakapuaki i ngā kōrero e tika ana. Heoi, kua tino rongonui te USB, ā, kei te pātai te iwi puta noa i te ao mō te mākete USB4. Mai i te tīmatanga o te USB 1.0 me te atanga tuku raraunga 1.5Mbps, kua maha ngā whakatipuranga o te USB. He maha ngā whakatakotoranga pēnei i te USB 1.0, USB 2.0, me te USB 3.0, ā, ko ngā āhua atanga me ngā hoahoa ko te USB Momo-A, USB Momo-B, me te USB Momo-C e tino kitea ana i tēnei wā, me ētahi atu. Ehara i te mea he tere ake te tuku a te USB4 engari he pai ake te hototahi (e tautoko ana i te hototahi whakamuri, arā, te hototahi ki ngā putanga iti ake). Ka taea e ia te hono atu i te nuinga o ngā taputapu me te utu i a rātou. Mena kei te tautoko tō waea, rorohiko, mata, pūreretā, me ētahi atu i te USB4, ko te tikanga, me whai taura raraunga anake koe e tautoko ana i te USB4 hei hono i ngā taputapu, ka nui ake te watea o te tari kāinga. Kāore koe e hiahia ki te hoko i ngā taura whakawhiti atanga rerekē. Nō reira, ka taea e te USB4 te whakanui ake i te kanorau me te watea o tā tātou aratau mahi. Hei tāpiritanga, ko tētahi atu āhuatanga whakamiharo o te USB4 ko tōna tūmanakohanga kia whakamahia ki ngā taputapu taha e tautoko ana i te rorohiko matauranga horihori.
01 USB4 me te USB3.2
He paerewa hou te USB 3.2 i tukuna e te whakahaere USB-IF. I whakaurua mai i te marama o Hepetema 2017. Mai i te tirohanga hangarau, he whakapainga, he tāpiritanga hoki te USB 3.2 ki te USB 3.1. Ko te huringa matua ko te whakanui ake i te tere tuku raraunga ki te 20 Gbps, ā, kei te whai tonu te atanga i teMomo-Ckaupapa i whakatūria i te wā o te USB 3.1, kāore e tautoko ana i ngā atanga Momo-A me Momo-B. E whakamahi ana a USB4 me USB3.2 i ngā atanga Momo-C, engari he tino uaua ake te USB4. Ka tautoko a USB4 i te tuku me te whiwhi raraunga manaaki-ki-te-kaihautū, PCI Express® (PCIe®), te oro/ataata DisplayPort, me te USB i te wā kotahi mā te atanga Momo-C kotahi i runga i te hononga kotahi. Ka taea e ngā kaihautū e rua o USB4 te whakawhiti i ngā mōkihi raraunga IP mā te kauhanga manaaki-ki-te-kaihautū; Ko te tikanga o te tukunga DisplayPort me te kauhanga USB ka taea te tuku oro, ataata, raraunga, me te hiko mā te atanga kotahi, he tere ake i te whakamahi i te USB3.2. Hei tāpiri, ka taea e te tukunga kauhanga PCIe te whakarato i te whānui o te hononga, te iti o te whakaroa, me te whakatutuki i te putanga nui mō te rokiroki kaha nui, te matauranga horihori taha, me ētahi atu whakamahinga.
Ka whakauruhia e te USB4 ngā hongere tuku me te hopu e rua ki roto i te atanga USB-C kotahi, me te tere tae atu ki te 20 Gbps me40 Gbps, ā, ka taea e ia hongere te tere raraunga tata ki te 10 Gbps, 20 Gbps rānei. Mō ngā kaiwhakawhanake maramara, he mea tino nui tēnei raraunga. Me mōhio rātou i roto i te aratau Thunderbolt3, ko te tere raraunga i runga i ia hongere tuku me te whiwhi he 10.3125 Gbps, 20.625 Gbps rānei. I roto i te aratau USB tuku iho, kotahi anake te hongere tuku/whiwhi e rere ana i te tere o5 Gbps (USB3.0) or 10 Gbps (USB3.1), i te mea e rere ana ngā hongere e rua o te USB3.2 i te tere o te 10 Gbps.
Mō te roa o te mau, ko ngā wāhanga e mau ana i te kaha o te atanga Momo-C ko te anga whakarewa o waho, he kaha ake, he iti ake te tūponotanga ki te pakaru. Ko te hongere raraunga matua e tiakina ana e te taupoki āhua-āwhata, e uaua ai te pakaru. E tohu ana ngā whakaritenga hoahoa ko teMomo-C USBka taea te tu atu i te neke atu i te 10,000 mono-mai me ngā momotu me te kore e pakaru. Mēnā ka tatauhia i runga i te 3 mono-mai me ngā momotu ia rā, ka taea te whakamahi i te atanga USB Momo-C mō te iti rawa 10 tau.
02 Te Whakateretere i te Whakatakotoranga o te USB4
I muri i te tukunga mana o te kawa USB 3.2, i roto i te wā poto noa iho ka panuitia e te whakahaere USB ngā whakatakotoranga o te USB 4. He rerekē ki ngā paerewa o mua pērā iUSB 3.2, i ahu mai i te kawa o te USB ake, kāore te USB 4 e tango i ngā whakatakotoranga USB i tōna taumata taketake engari e tango ana i te kawa Thunderbolt 3 kua whakakitea katoatia e Intel. Koinei te huringa nui rawa atu i roto i te whanaketanga o te USB i ngā tekau tau kua pahure ake nei. Ina whakamahia he hononga Momo-C mō te hononga, ka whakakapia ngā mahi a te USB4 e ngā mahi a te USB 3.2, ā, ka taea e te USB 2.0 te whakahaere i te wā kotahi. Ko te USB 3.2 Enhanced SuperSpeed tonu te hanganga taketake mō te tuku "raraunga USB" i runga i te raina tinana USB 4. Ko te rerekētanga nui i waenga i te USB4 me te USB 3.2 kei roto i te hononga-hononga a te USB4. Kua hangaia te USB4 me ngā kauhanga hei tuku tahi i ngā raraunga mai i ngā kawa maha i runga i te atanga tinana kotahi. Nō reira, ka taea te tiritiri hihiri i te tere me te kaha o te USB4. Ka taea e te USB4 te tautoko i ētahi atu kawa whakaaturanga, i te whakawhitiwhiti kōrero manaaki-ki-te-kaihautū rānei i te wā e haere tonu ana te tuku raraunga. Hei tāpiri, kua whakapiki ake a USB4 i te tere whakawhitiwhiti kōrero mai i te 20 Gbps (Gen2x2) o te USB 3.2 ki40 Gbps (Gen3x2)i runga i te hoahoanga ara-rua, ara-rua, ngāwari-rua taua.
Ehara i te mea ka tutuki noa i te USB4 te USB tere-teitei (i runga i te USB3), engari ka tautuhia hoki ngā kauhanga whakaatu i runga i te DisplayPort me ngā kauhanga uta/penapena i runga i te PCIe.
Āhuatanga whakaaturanga: Ko te kawa kauhanga whakaaturanga o te USB4 e hangai ana ki te DisplayPort 1.4a. E tautoko ana te DP 1.4a i te8k i te 60Hz or 4k i te 120HzMe tautoko te kaihautū USB4 i a DisplayPort i ngā tauranga katoa o raro. Mena ka whakamahia e koe te tauranga USB 4 hei tuku ataata me ngā raraunga i te wā kotahi, ka tohaina e te tauranga te whānui o te raraunga. Nō reira, mena e 20% noa iho o te whānui o te raraunga e hiahiatia ana e te ataata hei taraiwa i tō aroturuki 1080p (he pokapū anō hoki), ka taea te whakamahi i te 80% e toe ana o te ataata hei whakawhiti kōnae mai i tētahi SSD o waho.
Mō ngā kauhanga PCIe: He kōwhiringa te tautoko mō te PCIe e ngā kaihautū USB4. Me tautoko ngā pokapū USB4 i ngā kauhanga PCIe, ā, me whai pana PCIe ā-roto.
Ko tētahi wāhanga nui o te whakatakotoranga USB 4 ko te kaha ki te whakarerekē i te nui o ngā rauemi e wātea ana ina tukuna ana ngā ataata me ngā raraunga mā te hononga kotahi. Nō reira, me kī he mōrahi tōu40 Gbps USB 4ā, kei te tārua i ngā kōnae nunui mai i tētahi SSD o waho, ka tukuna ki tētahi whakaaturanga 4K. Mehemea e hiahiatia ana e te pūtake ataata te 12.5 Gbps. I tēnei wā, ka tohaina e te USB 4 te 27.5 Mbps e toe ana ki te puku tārua.
Ka whakauruhia e te USB-C te "aratau rerekē", arā, te kaha ki te tuku ataata DisplayPort/HDMI mai i te tauranga Momo-C. Heoi, kāore te whakatakotoranga 3.x o nāianei e whakarato i tētahi tikanga pai mō te wehewehe rauemi. E ai ki a Saunders, ka taea e te aratau alt DisplayPort te wehewehe tika i te whānui o te raraunga USB me ngā raraunga ataata ki te 50/50, engari kāore te aratau alt HDMI e whakaae ki te whakamahi i ngā raraunga USB i te wā kotahi.
Ka tautuhia e te USB4 he paerewa o te 40Gbps, e āhei ai te tiritiri hihiri o te whānui o te hononga kia taea ai e te taura raraunga kotahi te whakatutuki i ngā mahi maha. Mā te USB4, ka taea te tuku PCIe me te whakaatu raraunga i runga i te aho kotahi i te wā kotahi, me ngā mahi USB tuku iho, ā, ka taea hoki te whakarato hiko (mā te USB PD) i roto i te huarahi tino watea. I te heke mai, ko te nuinga o ngā taputapu taha, ahakoa he whatunga tere-teitei, he kāri whakairoiro o waho, he whakaaturanga whakamārama-teitei, he taputapu rokiroki tere-teitei kaha-nui, he mīhini kotahi me tētahi atu mīhini rānei, ka taea te hono atu mā te atanga Momo-C. Heoi anō, ki te whakatinanahia e ēnei taputapu te USB4 Hub, ka taea hoki e koe te hono atu i ētahi atu taputapu i roto i te raupapa, i ngā peka rānei mai i ēnei taputapu, he tino watea tēnei.
