Iyo Yekupedzisira Inotungamira ku USB4 Kubva pa40Gbps Kumhanya, Dynamic Bandwidth kusvika Yakazara-Basa One-Cable Connection.
Kubva pakabuda USB4, tanga tichidhinda zvinyorwa zvakawanda uye zvinongedzo kuti tigovane ruzivo rwakakodzera. Nekudaro, mukurumbira wakakwira zvekuti vanhu kwese kwese vari kubvunza nezve USB4 musika. Kutanga kubva pakutanga USB 1.0 nguva uye 1.5Mbps data transmission interface, USB yapfuura nemuzvizvarwa zvakawanda. Pakave nezvakawanda zvakatemwa zvakaita se USB 1.0, USB 2.0, uye USB 3.0, uye maumbirwo emhando uye zvirongwa zvekugadzira zvinosanganisira USB Type-A, USB Type-B, uye ikozvino inonyanya kuzivikanwa USB Type-C, etc. USB4 haingove inokurumidza kutapurirana spidhi asiwo ine zvirinani kuenderana (inotsigira kuenderana kumashure, ndiko kuti, kuenderana neshanduro yakaderera). Inogona kubatanidza anenge ese maturusi zvakanyanya uye nekuichaja. Kana foni yako, komputa, tarisisa, printa, nezvimwe zvese zvinotsigira USB4, zvino ne theoretically, iwe unongoda data tambo inotsigira USB4 kubatanidza zvishandiso, zvichiita kuti hofisi yemba ive nyore. Iwe hauchadi kutenga akasiyana interface ekushandura tambo. Naizvozvo, USB4 inogona kuita kuti maitiro edu ekushanda ave akasiyana uye ari nyore. Pamusoro pezvo, chimwe chinhu chinoshamisa che USB4 ndechekuti inotarisirwa kuiswa mumipendero michina inotsigira yekugadzira njere komputa.
01 USB4 vs. USB3.2
USB 3.2 chiyero chitsva chakaburitswa ne USB-IF sangano. Yakave yakatangwa kare munaSeptember 2017. Kubva pakuona kwehutano, USB 3.2 inovandudza uye inowedzera ku USB 3.1. Shanduko huru ndeyekuti kukurumidza kwekufambisa data kwakawedzera kusvika ku20 Gbps, uye iyo interface ichiri kuteveraType-Cchirongwa chakagadzwa munguva ye USB 3.1, isingachatsigire Type-A uye Type-B nzvimbo. Ose ari maviri USB4 uye USB3.2 anoshandisa Type-C nzvimbo, asi USB4 yakanyanya kuoma. USB4 inotsigira panguva imwe chete kutapurirana uye kugashira kweanotambira-kune-anotambira, PCI Express® (PCIe®), DisplayPort odhiyo/vhidhiyo, uye USB data kuburikidza neiyo yakafanana Type-C interface pane imwechete link. Maviri USB4 mauto anogona kuchinjana IP data packet kuburikidza ne host-to-host tunnel; DisplayPort uye USB tunnel kutapurirana zvinoreva kuti odhiyo, vhidhiyo, data, uye simba zvinogona kufambiswa kuburikidza neiyo yakafanana interface, iyo inokurumidza kupfuura kushandisa USB3.2. Uye zvakare, PCIe mugero wekutapurirana unogona kupa yakakwira bandwidth, yakaderera latency, uye kuwana yakakwira kuburikidza nehombe-yakawanda chengetedzo, mupendero wehungwaru hwekunyepedzera, uye mamwe makesi ekushandisa.
USB4 inosanganisa nzira mbiri dzekutumira uye dzekugamuchira mune imwechete USB-C interface, ine chiyero chekusvika makumi maviri Gbps uye.40 Gbps, uye chiteshi chega chega chinogona kuva nehuwandu hwe data hunosvika gumi Gbps kana 20 Gbps. Kune vanogadzira chip, iyi data yakakosha. Vanofanira kuziva kuti muThunderbolt3 mode, chiyero che data pane imwe neimwe nzira yekufambisa uye yekugamuchira ndeye 10.3125 Gbps kana 20.625 Gbps. Mune yechinyakare USB modhi, imwe chete yekufambisa / yekugamuchira chiteshi inomhanya pamwero we5 Gbps (USB3.0) or 10 Gbps (USB3.1), nepo nzira mbiri dze USB3.2 dzinomhanya pamwero we10 Gbps.
Panyaya yekusimba, iyo inotakura simba-yemhando yeType-C interface inonyanya kuve yekunze simbi casing, iyo yakasimba uye isinganyanye kukuvadza. Iyo yepakati data chiteshi inodzivirirwa nearc-shaped cover, zvichiita kuti zviome kukuvadzwa. Zvido zvekugadzira zvinoratidza kutiUSB Type-Cinogona kumira kupfuura 10,000 plug-ins uye unplugs pasina kukuvara. Kana ikaverengerwa zvichibva pamaplug-ins matatu uye unplugs pazuva, iyo USB Type-C interface inogona kushandiswa kweanodarika makore gumi.
02 Yakakurumidza Kutumirwa kwe USB4
Mushure mekuburitswa zviri pamutemo kweiyo USB 3.2 protocol, sangano reUSB rakakurumidza kuzivisa zvakatemwa zve USB 4 mukati menguva pfupi. Kusiyana nemitemo yapfuura yakadai seUSB 3.2, iyo yaive yakavakirwa paiyo USB's protocol, USB 4 haichatore zvirevo zve USB padanho rayo rakakosha asi inotora Thunderbolt 3 protocol yakaburitswa neIntel zvizere. Iyi ndiyo shanduko huru mukuvandudzwa kwe USB mumakumi emakore apfuura. Paunenge uchishandisa Type-C chinongedzo chekubatanidza, mabasa e USB4 anotsiva aya e USB 3.2, uye USB 2.0 inogona kumhanya panguva imwe chete. USB 3.2 Yakakwidziridzwa SuperSpeed inoramba iri iyo yekutanga masisitimu e "USB data" kutapurirana pa USB 4 yemuviri mutsara. Musiyano mukuru pakati pe USB4 ne USB 3.2 uri pakuti USB4 inotarisana-yakatarisana. USB4 yakagadzirwa nematanho ekufambisa pamwe chete data kubva kune akawanda maprotocol pane imwechete yemuviri interface. Saka, kumhanya uye kugona kwe USB4 kunogona kugovaniswa zvine simba. USB4 inogona kutsigira mamwe maprotocol ekuratidzira kana host-to-host kutaurirana uku kuendesa data kuchiri kuenderera. Pamusoro pezvo, USB4 yakawedzera kumhanya kwekutaurirana kubva pa20 Gbps (Gen2x2) ye USB 3.2 kuenda40 Gbps (Gen3x2)pane imwechete mbiri-nzira, mbiri-yakapusa yekuvaka.
USB4 haingogone chete yakakwira-kumhanya USB (yakavakirwa pa USB3), asi zvakare inotsanangudza nzira dzekuratidzira dzakavakirwa paDisplayPort uye kurodha/chitoro tunnel kwakavakirwa paPCIe.
Ratidza chimiro: Iyo inoratidzira tunnel protocol ye USB4 yakavakirwa paDisplayPort 1.4a. DP 1.4a pachayo inotsigira8k uye 60Hz or 4k pa120Hz. Iyo USB4 host inoda kutsigira DisplayPort pane ese akadzika madoko. Kana iwe ukashandisa USB 4 chiteshi kuendesa panguva imwe chete vhidhiyo uye data, chiteshi chinogovera bandwidth zvinoenderana. Naizvozvo, kana vhidhiyo ichingoda 20% yebandwidth kutyaira yako 1080p monitor (inovawo hub), ipapo iyo 80% yasara yevhidhiyo inogona kushandiswa kuendesa mafaera kubva kune yekunze SSD.
Panyaya yePCIe tunnels: Tsigiro yePCIe ne USB4 mauto inosarudzika. USB4 hubs inofanirwa kutsigira PCIe tunnels uye yemukati PCIe switch inofanira kunge iripo.
Chikamu chakakosha cheiyo USB 4 kutsanangurwa ndiko kugona kugadzirisa zvine simba huwandu hwezviwanikwa zviripo kana uchitumira vhidhiyo uye data kuburikidza nekubatana kwakafanana. Saka, ngatiti iwe une huwandu hwe40 Gbps USB 4uye vari kukopa mafaera mahombe kubva kune yekunze SSD uye kuburitsa kune 4K kuratidza. Ngatitii vhidhiyo sosi inoda ingangoita 12.5 Gbps. Muchiitiko ichi, USB 4 ichagovera yasara 27.5 Mbps kune backup drive.
USB-C inosvitsa "imwe nzira", iko kugona kufambisa DisplayPort/HDMI vhidhiyo kubva paType-C port. Zvisinei, ikozvino 3.x tsanangudzo haipe nzira yakanaka yekuparadzanisa zviwanikwa. Sekureva kwaSaunders, iyo DisplayPort alt modhi inogona kunyatso kupatsanura bandwidth pakati pe USB data nevhidhiyo data mu50/50, nepo HDMI alt modhi isingabvumire kushandiswa panguva imwe chete yedata re USB.
USB4 inotsanangura chiyero che 40Gbps, ichigonesa kugovana zvine simba kwebhanwidth kuitira kuti imwe data tambo inogona kuzadzisa akawanda mabasa. Ne USB4, zvinokwanisika kuendesa PCIe panguva imwe chete uye kuratidza data pamusoro pemutsara mumwe chete, pamwe neachinyakare USB mabasa, uye kunyange kupa simba (kuburikidza ne USB PD) nenzira iri nyore kwazvo. Mune ramangwana, akawanda madhivhari emidziyo, angave ari epamusoro-kumhanya network, ekunze makadhi emifananidzo, yakakwirira-tsanangudzo yekuratidzira, yakakura-yepamusoro-yepamusoro-inomhanya midziyo yekuchengetedza, kana kunyange muchina mumwe nemumwe muchina, inogona kubatanidzwa kuburikidza neType-C interface. Uyezve, kana zvishandiso izvi zvikaita USB4 Hub, unogona zvakare kubatanidza mamwe maturusi munhevedzano kana matavi kubva kumidziyo iyi, iri nyore kwazvo.
