USB4 2.0 yave kuwanikwa kune vanogadzira uye inovimbisa hukuru hwekumhanyisa kuvandudza
Munguva pfupi yapfuura, kuburitswa kweiyo itsva USB 4.0 kutsanangurwa kwakaziviswa, iyo Linux yakatotora nekuibatanidza muiyo huru kernel uye iyo rutsigiro rwave rwuripo kwemwedzi yakati wandei ikozvino.
Saka zvino, nhau yakaburitswa kuti iri kushanda yatova mukuvandudzwa (USB4) chii inobvumira kushanda kusvika ku80 Gb / s, zvichibva pachimiro chitsva chedhizaini yekuvaka, uchishandisa iripo 40 Gbps USB Type-C tambo dzepasi uye dzichangotsanangurwa 80 Gbps USB Type-C tambo dzinoshanda.
Maive munaGunyana 2019 iyo yekutanga vhezheni ye USB 4 yakaziviswa uye kuti izvi inovimba zvakanyanya neiyo Thunderbolt 3 standard uye inopa zvakafanana zvekumhanya zvakanyanya (kusvika ku40 Gb/s).
USB4 1.0 inokutendera kuti ubatanidze 4K kana 8K kuratidzwa kuburikidza ne USB, batanidza nhevedzano yeakasiyana siyana e USB pachiteshi chimwe chete, pakati pezvimwe zvinhu.
Makore matatu gare gare, yave nguva yekuti vhezheni 2.0 ye USB4 standard iitike. Iyo chaiyo tekinoroji yakatarwa ye USB Implementers Forum, , que ane mutoro wechiyero pachayo, haisati yaburitswa, asi zvakaburitswa zvinoti shamisa.
USB Inosimudzira Boka inoti inoronga kuburitsa USB4 2.0 yakajairwa pamberi pe USB Developer Days 2022 zviitiko, yakarongwa muna Mbudzi, asi zvingangove makore mashoma tambo itsva, hubs, maPC uye nharembozha dzakashongedzerwa neiyi tekinoroji itsva inowanikwa kune veruzhinji.
USB Promoter Group, iyo inosanganisira Apple, Microsoft, Intel, HP, STM nevamwe, yakazivisa mukuburitswa kwenhau kuti USB4 2.0 tambo dzichashandisa USB-C yekubatanidza, sezvaitarisirwa. Asi nhau dzinonyanya kushamisa ndeidzi:
"USB4 2.0 ichagonesa kusvika ku80Gb/s kushanda, zvichibva pachimiro chitsva chemuviri, uchishandisa 40Gb/s iripo uye ichangobva kutsanangurwa 80Gb/s USB Type-C tambo dzepasi." s Active USB Type-C tambo". USB-C uye USB Power Delivery yakatarwa ichagadziridzwa kuti igone kugonesa inotevera nhanho yekufambisa kwedata.
Iyo chiyero chitsva ichaunzawo itsva inoshanda USB-C tambo yakagadzirirwa zvakananga kumhanya kusvika ku80 Gbps. Zvigadziriso zviri kuitika kubvumidza kushanda kwepamusoro USB 3.2, DisplayPort, uye PCIe data tunneling kutora mukana wekuwedzera bandwidth.
Heino pfupiso yezvimiro zvinozivikanwa kusvika zvino:
- kusvika ku80 Gb/s kushanda, uchishandisa 40 Gbps USB-C tambo dzepasi uye dzichangotsanangurwa 80 Gbps USB-C tambo dzinoshanda.
- gadziriso yedata uye ratidza maprotocol kuti ushandise zvirinani iyo yakawedzera iripo bandwidth
- Zvigadziriso kune USB data architecture ikozvino inobvumira USB 3.2 kudarika 20 Gb/s
- yakagadziridzwa kuti ienderane neazvino mavhezheni eDisplayPort uye PCIe zvakatemwa
- kunoenderana neshure ne USB4 1.0, USB 3.2, USB 2.0 uye Thunderbolt 3.
Kubva pane izvi zvakatemwa, zvinofanirwa kucherechedzwa kuti 80 Gbps ine simba rakawanda, asi iyo yakatarwa haina kugadzirwa kuti igopirwa zvachose kune imwechete yekubatanidza. Asi, inoitirwa kugovera iyo 80 Gb/s pakati pemidziyo yakasiyana yakabatana nehabhu kana chiteshi chekumisikidza.
Kana riri zita, zvingaite sezvisinganzwisisike kudaidza chigadzirwa ichi sechingori "vhezheni 2.0" ye USB4, kana iyo yekumhanyisa inowedzera ichiita seinopembedza zita USB5. Zvisinei, chiyero chave chichivhiringidza kwemakore mashomanana ikozvino.
USB 3.2 chaizvoizvo akati wandei akasiyana mazinga: USB 3.2 Gen 1 (inozivikanwawo seyepakutanga USB 3.0), USB 3.2 Gen 2, USB 3.2 Gen 1x2, uye USB 3.2 Gen 2x2 (inova ndiyo yakazara 20Gb chiyero). USB4 yaichengeta zvinhu zviri nyore sezvo yaingove neyakafanana uye kugona seThunderbolt 3.
Pakupedzisira zvakakodzera kutaura izvozvo mukuburitswa kwenhau kwakapihwa ne USB Promota Boka, vakataura izvozvo iyo yekuvandudza ndeye "chaizvo kune vanogadzira panguva ino", uye iyo yekupedzisira yekumaka uye nhungamiro yekushambadzira (kusanganisira zvinhu zvakaita selogos) ichauya gare gare. Mukutaura, tinogona kuona kuti vazhinji vari kutadzawo kushivirira nepfungwa yekukwanisa kuendesa yakaenzana ne4K Blu-ray mumasekondi mashanu.
Iboka racho haana kupa zvizere ruzivo pachiyero chitsva, asi akati ichave kumashure inoenderana ne USB4 1.0, USB 3.2, USB 2.0 uye Thunderbolt 3 zviyero.
Kana iwe uchifarira kuziva zvakawanda nezvazvo, unogona kutarisa ruzivo Mune inotevera chinongedzo.
