MIPI Lub Koob Yees Duab VS USB Lub Koob Yees Duab

Kev xaiv ntawm qhov zoo tshaj plaws-haum interface nyob ntawm ntau yam.Thiab MIPI thiab USB tseem yog ob lub koob yees duab nrov tshaj plaws interfaces.Ua tib zoo taug kev mus rau hauv lub ntiaj teb ntawm MIPI thiab USB interfaces thiab tau txais qhov sib piv ntawm qhov tshwj xeeb.

Ob peb xyoos dhau los no, lub zeem muag pom tau hloov zuj zus los ntawm lo lus buzz mus rau cov cuab yeej siv dav dav siv thoob plaws hauv kev lag luam, kev kho mob, khw muag khoom, kev lom zem, thiab kev ua liaj ua teb.Nrog rau txhua theem ntawm nws cov evolution, embedded lub zeem muag tau ua kom muaj kev loj hlob tseem ceeb ntawm cov koob yees duab interfaces muaj los xaiv.Txawm li cas los xij, txawm hais tias muaj kev nce qib thev naus laus zis, MIPI thiab USB interfaces tseem yog ob hom nrov tshaj plaws rau feem ntau ntawm cov ntawv pom kev pom.

Qhov kev xaiv ntawm qhov zoo tshaj plaws-haum interface nyob ntawm ntau yam xws li tus ncej tus nqi / bandwidth xav tau, kev daws teeb meem, cov ntaub ntawv hloov kev ntseeg tau, cable ntev, complexity, thiab - tau kawg - tag nrho cov nqi.Hauv tsab xov xwm no, peb saib ob qho tib si interfaces hauv kev nthuav dav kom nkag siab zoo dua lawv lub peev xwm thiab kev txwv.

720P Lub Koob Yees Duab Module

Saib tob dua ntawm MIPI thiab USB interfaces

 

Lub koob yees duab MIPI tsis muaj dab tsi tab sis akoob yees duab modulelos yog lub kaw lus uas siv MIPI interface hloov cov duab los ntawm lub koob yees duab mus rau lub party platform.Hauv kev sib piv, lub koob yees duab USB siv USB interface rau kev hloov cov ntaub ntawv.Tam sim no, cia peb nkag siab txog ntau hom MIPI thiab USB interfaces thiab qhov twg lawv siv.

MIPI interface

MIPI yog qhov feem ntau siv interface nyob rau niaj hnub no kev ua lag luam rau point-to-point duab thiab video kis tau tus mob ntawm lub koob yees duab thiab tus tswv tsev pab kiag li lawm.Nws tuaj yeem raug ntaus nqi rau MIPI qhov yooj yim ntawm kev siv thiab nws lub peev xwm los txhawb ntau yam kev ua haujlwm siab.Nws kuj los nruab nrog cov yam ntxwv muaj zog xws li 1080p, 4K, 8K thiab tshaj video thiab cov duab daws teeb meem siab.

MIPI interface yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov xws li head-mounted virtual reality devices, smart traffic applications, gesture recognition systems, drones, face recognition, security, surveillance systems, etc.

 

MIPI CSI-2 Interface

MIPI CSI-2 (MIPI Lub Koob Yees Duab Serial Interface 2nd Generation) tus qauv yog qhov ua tau zoo, siv tau zoo, thiab yooj yim-rau-siv interface.MIPI CSI-2 muaj qhov siab tshaj plaws bandwidth ntawm 10 Gb / s nrog plaub txoj kab cov ntaub ntawv - txhua txoj kab muaj peev xwm hloov cov ntaub ntawv mus txog 2.5 Gb / s.MIPI CSI-2 sai dua USB 3.0 thiab muaj cov txheej txheem txhim khu kev qha los daws cov vis dis aus los ntawm 1080p txog 8K thiab tshaj.Tsis tas li ntawd, vim nws cov nyiaj siv ua haujlwm qis, MIPI CSI-2 muaj ntau dua net duab bandwidth.

MIPI CSI-2 interface siv tsawg dua cov peev txheej los ntawm CPU - ua tsaug rau nws cov txheej txheem ntau yam.Nws yog lub koob yees duab default interface rau Raspberry Pi thiab Jetson Nano.Raspberry Pi lub koob yees duab module V1 thiab V2 kuj yog raws li nws.

Kev txwv ntawm MIPI CSI-2 Interface

Txawm hais tias nws yog qhov muaj zog thiab nrov interface, MIPI CSI tuaj nrog qee qhov kev txwv.Piv txwv li, MIPI koob yees duab cia siab rau cov tsav tsheb ntxiv los ua haujlwm.Nws txhais tau hais tias tsis muaj kev txhawb nqa rau cov duab sib txawv tshwj tsis yog cov tuam txhab tsim cov kab ke tiag tiag thawb rau nws!

USB interface

Lub USB interface nyiam ua qhov sib txuas ntawm ob lub tshuab - lub koob yees duab thiab PC.Txij li thaum nws paub zoo txog nws lub peev xwm plug-and-play, xaiv USB interface txhais tau hais tias koj tuaj yeem hais lus zoo rau kim, kos-tawm kev tsim kho lub sijhawm thiab cov nqi rau koj qhov kev pom kev sib cuam tshuam.USB 2.0, qhov qub version, muaj cov kev txwv tseem ceeb.Raws li thev naus laus zis pib dwindle, ntau ntawm nws cov khoom ua tsis sib xws.USB 3.0 thiab USB 3.1 Gen 1 interfaces tau tsim los kov yeej cov kev txwv ntawm USB 2.0 Interface.

USB 3.0 interface

Lub USB 3.0 (thiab USB 3.1 Gen 1) interface ua ke cov yam ntxwv zoo ntawm kev sib txawv.Cov no suav nrog plug-and-play compatibility thiab qis CPU load.Lub zeem muag kev lag luam tus qauv ntawm USB 3.0 kuj ua rau nws muaj kev ntseeg siab rau cov koob yees duab siab thiab ceev ceev.

Nws yuav tsum muaj tsawg kawg nkaus kho vajtse ntxiv thiab txhawb qis bandwidth - txog li 40 megabytes ib ob.Nws muaj qhov siab tshaj plaws bandwidth ntawm 480 megabytes ib ob.Qhov no yog 10 npaug sai dua USB 2.0 thiab 4 npaug sai dua GigE!Nws lub peev xwm ntsaws-thiab-ua si ua kom ntseeg tau tias cov khoom siv tsis pom kev tuaj yeem hloov pauv tau yooj yim - ua kom yooj yim los hloov lub koob yees duab puas.

Kev txwv ntawm USB 3.0 Interface

Qhov loj tshaj qhov tsis zoo ntawm USB 3.0 interface yog tias koj tsis tuaj yeem khiav cov kev daws teeb meem siab ntawm kev kub ceev.Lwm qhov kev poob qis yog tias koj tsuas tuaj yeem siv lub cable mus txog qhov deb ntawm 5 meters ntawm tus tswv tsev processor.Thaum cov cables ntev dua, lawv txhua tus haum nrog "boosters".Yuav ua li cas cov cables ua haujlwm ua ke nrog cov koob yees duab kev lag luam yuav tsum tau kuaj xyuas txhua tus neeg mob.
