GMSL vs. MIPI cameras: anci da GMSL cameras yana guda?

Don Allah suna a cikin sistemar vision kamatawa mai tsarin, misaliyar automotive, robotics, da shugaban kasa, interfaces kamera a kan rubutuwa da hanyar bandan gaba required don saukar da karfar data video mai kula resolution. Kawai, interfaces kamera ta duniya, misaliyar MIPI CSI-2 , USB 3.0 da GigE, still za'a iya amfani da wani abubuwan a cikin abokan, amma ana gabatar da su don abokan dai dai a requires hanyar rubutuwa da masu kebba da masu rubutuwa, da yanzu na same don Ethernet da CAN, mai a matsayi ake amfani daidai a cikin automobile, amma ana gabatar da su don saukar da masu kebba da masu rubutuwa video digital mai kula resolution a kan rubutuwa da hanyar masu kebba.

Da fatan rubutun tekonoloji, wani shafi da aka yi daga cikin wannan. Tekonolojin Serializer/Deserializer (SerDes) na kewaye mai tunani da rubutun data a cikin sabon sannan, suporta masu harshe kuma bayanin aiki mai tsari, a cikin amfani da data communication, telecommunication kuma amfani da ke nan da shine. Wannan tekonolojin link serial suna iya worked reliably a cikin samarun industrial kuma samarun gida, an yi rubutun data binciken da latinsa tare da. Amfani na farba SerDes tekonoloji ya ne daidai a cikin yin gabatarwa da ida/matambayi na input/output kuma interconnections bi aiki da rubutun data a cikin tashi coaxial cable ko differential pair cable.

Kamera Gigabit Multimedia Serial Link™ (GMSL) suka amfani da GMSL kuma GMSL2 tekonoloji-tekonoloji SerDes dai dai a yi rubutun video sabon sannan, data control bi-directional, kuma power a cikin tashi coaxial cable. A ga wannan, suna ba daidai ba a samfara farko kusa diwan interface GMSL kuma interface kamera MIPI tradisional kuma ana soya amfani da ke nan.

Mai gaskiya ya ci GMSL interface?

Interface Gigabit Multimedia Serial Link (GMSL) ya ci rubutun bayanai serial wanda kuma yana idafa daidaita a cikin samfari bayanai daidai, video daihijiyar, tsarin daihijiyar, bayanai kontrol bi-directional daga robotics to Advanced Driver Assistance Systems (ADAS), mai tsarin interface daihijiyar na jihunin daidai.

Takarda GMSL ya gabatar da bayanai a cikin serializer via serializer, ya same bayanai seriya a cikin deserializer via deserializer a cikin receiver don wannan bayanai a yi amfani. Amfani haka na bayanai an yi amfani daidaita don samfari bayanai video a cikin 6 gigabits per second (Gb/s).

Sandar GMSL ya kai serializers da deserializers don rubutun daga cikin HDMI, CSI-2, DSI, DSI asametri, eDP, oLDI, ne single/double/quadruple GMSL1/GMSL2, dai dai yanzu a cikin input ko output. Rubutun GMSL yana jihar daidaita aiki don rubuta data a cikin kabe coaxial ko tare da sabon cable differential (masanar STP, SPP, daga). Rubutun GMSL yana jihar daidaita aiki don rubuta data a cikin kabe coaxial ko sabon cable differential (masanar STP, SPP, daga), yayi kasance da idanƙasa da sabon pins input/output da interconnects, saman da integrity data da low latency. Suna suna GMSL camera bayan, wanda mutum mai shigarwa suka zuba makala na .

Harshe na MIPI Camera Interface

MIPI (Mobile Industry Processor Interface) ya ci gaba da aikin kungiyar seri na wata shirin da ke yi a cikin wannan suna da aka sami mai tsarin daga wannan aikin, ake samun hanyar domin daidaita ne daga wannan aikin. Aikin MIPI ya kamata wannan rubutu mai shirin, an yana MIPI CSI-2, ya ke yi aikin da aka sami domin daidaita ne daga wannan aikin da aka sami domin daidaita ne daga wannan aikin Camera Module da wani aiki na kompiyuta. Wannan abin da aka samfara domin daidaita ne MIPI CSI-2 ya sanya sabon bandawar 6Gb per second, da wannan rubutu da aka samun 5Gb/s.

Wannan rubutu MIPI CSI-25 ya kamata wannan rubutu mai shirin domin samun data domin daidaita ne daga sensor ta fiye na ido da ido na babban kompiyuta, ya kamata wannan rubutu domin samun data domin daidaita ne daga wannan rubutu domin samun data domin daidaita ne daga wannan rubutu domin samun data domin daidaita ne daga wannan rubutu. Da fatan wannan rubutu MIPI CSI-2 connection length ya gabatar da 30CM, ya gabatar domin samun daidaita ne daga wannan rubutu domin samun data domin daidaita ne daga wannan rubutu.

Binciken wannan GMSL interface suka ne MIPI camera interfaces

1. Masu rayuwa: Takarda GMSL SerDes suna aikin daidaita transmission ta 15M, ya kawai hanyar wannan ga 30CM ta MIPI CSI-2 interface.
2. Yadda EMI/EMC: Takarda GMSL suka samfara yadda EMI ta link din da programmable outputs na spread spectrum capabilities, ko ana yi hakuri external spread spectrum clock. GMSL suna shirin daidaita channel EMC tolerance ta high immunity mode (HIM) don samfara wani haifarinsa security cameras.
3. Automatic Retransmission Request (ARQ): GMSL suna iya ARQ method don samfara wani haifarsa daidaita data. Yadda data suna saiti ne suka samfara daga automatic retransmission to'a'a data suna gabata. Daga GMSL2, ARQ suna iya gudanar Cyclic Redundancy Checks (CRC) don gabatar shine paket ya gabata ko ba, don samfara system critical control functions.
4. Backward Compatibility: Ina hanyar GMSL a cikin samun gaba, ya kawo wannan samun gaban da ke daga samun wanda suka yi amfani da rubutuwa.
5. Saukin Virtual: Saukin virtual ya kawo SerDes a cikin samun gabatar da kamera. Deserializer GMSL ya kawo shirya da 16 kanar virtual, da na kanar virtual suka ne da MIPI CSI-2 na CSI-3.
6. Gurin Samun Da Ke Duk: Kamera GMSL ya kawo samun duk da NVIDIA® Jetson™ development kits da Connect Tech's Rogue, Rudi-AGX, da Rudi NX platforms, mai tsarin Jetson Xavier™ NX, don saita da iyalta da idafa na produktan vision.

Kammalawa

Kuna wani aikin da ke kuma suna, kamar rubutun shafi na guda ya kamata da yanzu hal latsaƙiwa ta rubutun USB, kuma da fatan haka GMSL ya ne labar rubutun mai tsaye masu duniya ga systemin vision embedded kama robotics, ADAS, systemin transportai mutumin karkashin, wannan. Rubutun GMSL ya yi amfani da dukkanci a cikin domain dai dai tare da wannan mutum mai soja daɗe da video data mai samfiri mai kwalita ayyukan.
