Michal Ždanský Sezvaitarisirwa, MacBooks matsva akagamuchira chiteshi cheThunderbolt (LightPeak) chitsva, uye mamwe makomputa eApple achatevera. Muchinyorwa chino, ndinoda kutarisa zvakadzama nezve iyo yakavharwa Kutinhira, zvese kubva kune tekinoroji uye yetioretical poindi yekuona.
Kutinhira pasi pegirazi rinokudza
Kunyangwe LightPeak yainyanya kutaura nezve optical fiber transmission, Thunderbolt, iyo yakaonekwa muMacBook Pro, ndeyesimbi, i.e. kutapurirana kwakavakirwa pamaerekitironi, kwete mafotoni. Izvi zvinoreva kuti isu tinogona kungorota nezve theoretical kumhanya kwe100 Gb/s parizvino, pamwe netambo dzemamita zana. Kune rimwe divi, nekuda kwemaerekitironi, Thunderbolt inogonawo kuchaja zvigadziriso zvekusvika pa100 W, uye mutengo uchange wakadzikira zvakanyanya nekuda kwekushaikwa kwemaoptics. Ini ndinofunga kuti remangwana optical vhezheni ichavawo nesimbi chikamu chekuchaja chete.
Thunderbolt inoshandisa PCI Express 2.0 interface iyo yainotaurirana nayo. Iyo ine dhizaini inosvika ku16 Gb/s. PCI Express ikozvino inonyanya kushandiswa nemakadhi emifananidzo. Nekudaro, Thunderbolt inova rudzi rwekunze PCI Express, uye mune ramangwana isu tinogonawo kutarisira ekunze makadhi emifananidzo akabatana kuburikidza neIntel's interface.
Thunderbolt, ingangoita sekuratidzwa neApple, inosanganiswa nediki DisplayPort mukudzokorora 1.1 uye inobvumira kumashure kuenderana nayo. Saka kana iwe ukabatanidza, semuenzaniso, Apple Cinema Display kuburikidza neThunderbolt, inoshanda zvakajairwa, kunyangwe iyo Apple yekutarisa isati yave neThunderbolt.
Chinonyanya kufadza ndechekuti iyo nyowani interface ine mbiri-chiteshi uye bidirectional. Iyo data inoyerera inogona kufamba nenzira yakafanana, zvichiita kuti data yose iendeswe kusvika ku40 Gb/s, asi nenyaya yekuti kumhanya kwepamusoro kwegwara rimwe munzira kuchiri 10 Gb/s. Saka zvakanakira chii? Semuenzaniso, unogona kuchinjanisa data pakati pezvishandiso zviviri panguva imwe chete nekumhanya kwepamusoro uchitumira chifananidzo kune chekunze chekutarisa.
Mukuwedzera, Thunderbolt inokwanisa iyo inonzi "daisy chaining", iyo inzira yekugadzira michina. Neiyi nzira, unogona kubatanidza serially kusvika kumidziyo mitanhatu ine Thunderbolt port iyo inoshanda semidziyo yekupinza / yekuburitsa uye anosvika maviri mamonitor ane DisplayPort pakupera kwecheni (nemamonitor maviri ichave 6 zvishandiso), izvo zvinoita. haifanirwe kuve neThunderbolt. Mukuwedzera, Thunderbolt ine kunonoka kudiki (2 nanoseconds) uye yakanyatso kufambisa kuwiriranisa, iyo yakakosha kwete chete kune daisy chaining.
USB 3.0 mhondi?
Thunderbolt inonyanya kutyisidzira USB 3.0, iyo ichiri kukura zvishoma nezvishoma. Iyo USB nyowani inopa yekumhanyisa kumhanya inosvika 5 Gb/s, kureva hafu yekugona kweThunderbolt. Asi izvo zvisingapi USB zvinhu zvakaita senge multi-channel kutaurirana, daisy chaining, uye ini handitombotarisire kushandiswa kweA/V composite kubuda. USB 3.0 saka ndiyo inokurumidza mukoma weiyo yapfuura mbiri vhezheni.
USB 3.0 inogona kuwedzera kubatanidzwa kubhodhi reamai kuburikidza nePCI-e, zvinosuruvarisa kuti Thunderbolt haitenderi izvi. Inoda kuitwa yakananga pabhodhi reamai, saka kana wanga uchifunga kuwedzera Thunderbolt kuPC yako, ndinofanira kukuodza mwoyo. Nekudaro, isu tinogona kutarisira Intel uye pakupedzisira vamwe vanogadzira mamaboard kuti vatange kuishandisa mune zvitsva zvigadzirwa.
Pasina kupokana, Thunderbolt mukwikwidzi akananga weiyo USB nyowani, uye pachave nehondo inotyisa pakati pavo. USB yakatorwa hondo yakafanana neyeiyo-nyowani FireWire interface. Kusvika nhasi, FireWire yave nyaya yevashoma, nepo USB iri pese pese. Kunyangwe Firewire yakapa yekumhanyisa yekufambisa, yakakanganiswa nekubhadharwa rezenisi, nepo USB rezinesi yaive yemahara (kunze kweiyo yakakosha-yekumhanya USB vhezheni). Nekudaro, Thunderbolt yakadzidza kubva mukukanganisa uku uye haidi muripo werezinesi kubva kune vechitatu-bato vanogadzira.
Saka kana Thunderbolt ikakunda nzvimbo yayo muzuva, mubvunzo uchave wekuti USB 3.0 ichadiwa zvachose. Kuenderana ne USB kucharamba kuchigoneka neThunderbolt kuburikidza nekudzikisira, uye yazvino USB 2.0 inokwana kune yakajairwa data kutamiswa kweflash drive. Saka iyo USB nyowani ichave nenguva yakaoma, uye mukati memakore mashoma Thunderbolt inogona kunge ichiibvisa zvachose. Pamusoro pezvo, 2 vatambi vakasimba kwazvo vanomira kumashure kweThunderbolt - Intel neApple.
Zvichanakira chii?
Kana tikakwanisa kutaura nezvenguva iripo, ipapo Kutinhira hakushandiswe mukuita, kunyanya nekuda kwekushaikwa kwemidziyo ine interface iyi. Hazvishamise kuti Apple yaive yekutanga kuratidza Thunderbolt mumabhuku ayo ezvinyorwa, uyezve, kusarudzika kunovimbiswa kwemwedzi yakawanda, zvirinani maererano nekubatanidzwa pamabhodhi eamai.
Nekudaro, vamwe vagadziri vari kungotanga kutamba neThunderbolt. Western Digital, Vimbiso a LaCie vakatozivisa kugadzirwa kwekuchengetwa kwedata uye zvimwe zvishandiso zvine Intel interface, uye zvinogona kutarisirwa kuti vamwe vatambi vakasimba vakaita senge. Seagate, Samsung, A-Dhata uye zvimwe zvichawedzerwa nokukurumidza, sezvo vashomanene vachada kurasikirwa nefungu idzva ravanogona kukwira pamusoro paro mukuzivikanwa. Apple yave rudzi rwechiratidzo chechokwadi maererano nekuitwa kwematekinoroji matsva, uye mazhinji matekinoroji aakatumira ave anenge akajairika mune imwe nguva, achitungamirwa neiyo yekutanga USB.
Tinogona kutarisira kuti Apple ichada kushandisa Thunderbolt mune zvakawanda zvezvigadzirwa zvayo. Kudzokororwa kutsva kweNguva Capsule inenge 100% yechokwadi, pamwe neMacs matsva nemamwe makomputa eApple achaunzwa munguva pfupi iri kutevera. Deployment inogonawo kutarisirwa kune iOS zvishandiso, uko Thunderbolt yaizotsiva iripo dock yekubatanidza. Izvo hazvigone kutaurwa zvechokwadi kuti zvichave gore rino, asi ini ndaizoisa ruoko rwangu mumoto nekuda kwekuti iyo iPad 3 uye iPhone 6 haichazvidzivirira.
Kana Thunderbolt ikanyatsobudirira kupaza pakati pemidziyo yeI / O, saka tinogona kutarisira mafashama ezvigadzirwa neiyi interface mukupera kwegore. Thunderbolt inoshanda zvakasiyana-siyana zvekuti inogona kutsiva zvese zvinongedzo zvenhaka pamwe neazvino machinjiro akadai seHDMI, DVI uye DisplayPort pasina kubwaira ziso. Pakupedzisira, hapana chikonzero nei isingakwanise kutsiva yekare LAN. Zvese zvinongoenderana nerutsigiro rwevagadziri uye kuvimba kwavo muchimiro chitsva uye, chekupedzisira asi chisiri chidiki, pane kuvimba kwevatengi.
Ouch. Zvakanaka, ijoke :)
Hapana chimwe chekutaura nezvazvo, kwete WOOOOW… !!! Ndiri kutarisira zvikuru nguva yandichange ndiine mini-pidi Mabook Air apo ichashanda zvakakwana mumugwagwa uye kana ndasvika kumba ndoibatanidza neCinema itsva uye ichava nemifananidzo ine simba uye inonzwika system inoshandiswa. mariri uye ini handizive chii chimwe uye kamwe kamwe ichava muchina une simba wekushandisa chero chinhu. Zvichava zvakanaka, changamire. Kana piritsi uye bhaisikopo zvingavawo zvakanaka :-)
