I-MIPI interface

I. I-MIPI MIPI (I-Mobile Industry Processor Interface) isifinyezo se-Mobile Industry Processor Interface.
I-MIPI (I-Mobile Industry Processor Interface) iyindinganiso evulekile yamaphrosesa ezinhlelo zokusebenza zamaselula eqalwe yi-MIPI Alliance.

Imininingwane eseqediwe futhi esehlelweni imi kanje: Bhala incazelo yesithombe lapha
LESIBILI, INKCAZELO YE-MIPI ALLIANCE YE-MIPI DSI
1, ukuhunyushwa kwebizo
II-CS ye-DCS (I-DisplayCommandSet) iyisethi emisiwe yemiyalo yamamojula wokubonisa kwimodi yomyalo.
I-DSI, CSI (DisplaySerialDisplay, CameraSerialInterface)
I-DSI ichaza isixhumi esibonakalayo esinesivinini esikhulu phakathi kwephrosesa nemojula yokubonisa.
I-CSI ichaza isixhumi esibonakalayo esinesivinini esikhulu phakathi kwephrosesa nemojula yekhamera.
I-D-PHY: Ihlinzeka ngezincazelo zesendlalelo esibonakalayo se-DSI ne-CSI
2, Isakhiwo esinezingqimba ze-DSI
I-DSI ihlukaniswe yaba izingqimba ezine, ezihambisana ne-D-PHY, i-DSI, imininingwane ye-DCS, umdwebo wesakhiwo se-hierarchical kanje:
I-PHY ichaza i-transmission medium, isekethe yokufaka/yokukhiphayo, kanye newashi nendlela yesignali.
Isendlalelo Sokuphatha Umzila: Thumela futhi uqoqe ukugeleza kwedatha emzileni ngamunye.
Isendlalelo Sephrothokholi Yezinga Eliphansi: Sichaza indlela ozimele nezinqumo ezifakwe ngayo kuzimele, ukutholwa kwamaphutha, nokunye.
Isendlalelo sohlelo lokusebenza: Sichaza umbhalo wekhodi wezinga eliphezulu kanye nokugeleza kwedatha yokudlulisa.

3, Imodi yomyalo kanye nevidiyo
Ama-peripheral ahambisana ne-DSI asekela amamodi okusebenza e-Command noma Video, okuyimodi enqunywa i-peripheral architecture Imodi yomyalo isho ukuthumela imiyalo nedatha kusilawuli esinenqolobane yokubonisa.Umsingathi ulawula ngokungaqondile i-peripheral ngemiyalo.
Imodi yomyalo isebenzisa isixhumi esibonakalayo sezindlela ezimbili Imodi yevidiyo isho ukusetshenziswa kokusakaza kwesithombe sangempela ukusuka kumsingathi kuya kumngcele.Le modi ingadluliselwa kuphela ngesivinini esiphezulu.

Ukunciphisa inkimbinkimbi futhi wonge izindleko, amasistimu evidiyo kuphela angase abe nendlela eyodwa kuphela yedatha
Isingeniso ku-D-PHY
1, D-PHY ichaza i-PHY ehambisanayo, enesivinini esikhulu, enamandla aphansi, ebiza kancane.
Ukucushwa kwe-PHY kuhlanganisa
Umzila wewashi
Umzila wedatha owodwa noma ngaphezulu
Ukucushwa kwe-PHY kweMizila emibili kuboniswe ngezansi
Bhala incazelo yesithombe lapha
Izinhlobo ezintathu zomzila oyinhloko
Umzila wewashi lendlela eyodwa
I-One-way data Lane

Imodi yesiginali yesivinini esikhulu (yokudlulisa idatha ngesivinini esikhulu): 80Mbps kuya ku-1Gbps/Lane
Iphrothokholi yeleveli ephansi ye-D-PHY icacisa ukuthi ubuncane beyunithi yedatha yibhayithi
Uma uthumela idatha, kufanele ibe phansi ngaphambili futhi ibe phezulu ngemuva.
I-D-PHY yezinhlelo zokusebenza zeselula
I-DSI: Bonisa isikhombimsebenzisi se-serial
Umzila wewashi owodwa, umzila wedatha owodwa noma ngaphezulu
I-CSI: I-Camera Serial Interface
2, Imojula yomzila
I-PHY iqukethe i-D-PHY (Lane Module)
I-D-PHY ingase iqukathe:

4, imodi yokusebenza
Izindlela ezintathu zokusebenza ze-Data Lane
Imodi yokubalekela, Imodi yesivinini esikhulu, imodi yokulawula
Izehlakalo ezingenzeka ukusuka kusimo sokuma semodi yokulawula yilezi:
Isicelo semodi yokubalekela (LP-11-LP-10-LP-00-LP-01-LP-00)
Isicelo semodi yesivinini esikhulu (LP-11-LP-01-LP-00)
Isicelo sokuguqula (LP-11-LP-10-LP-00-LP-10-LP-00)
I-Escape mode wukusebenza okukhethekile kwe-data Lane kusimo se-LP
Kule modi, ungafaka eminye imisebenzi eyengeziwe: LPDT, ULPS, Trigger
I-Data Lane ingena kumodi ye-Escape nge-LP-11- LP-10-LP-00-LP-01-LP-00
Uma usemodini ye-Escape mode, umthumeli kufanele athumele umyalo we-1 8-bit ephendula isenzo esiceliwe
I-Escape mode isebenzisa i-Spaced-One-Encoding Hot
I-Ultra-Low Power State
Kulesi simo, imigqa ayinalutho (LP-00)
Isimo samandla aphansi kakhulu se-Clock Lane
I-Clock Lane ingena kusimo se-ULPS nge-LP-11-LP-10-LP-00
- Phuma kulesi simo nge-LP-10 , TWAKEUP , LP-11, isikhathi esincane se-TWAKEUP ngu-1ms
Ukudluliswa kwedatha enesivinini esikhulu
Isenzo sokuthumela idatha ye-serial enesivinini esikhulu sibizwa ngokuthi ukudluliswa kwedatha okunesivinini esiphezulu noma ukucupha (ukuqhuma)
Yonke iminyango ye-Lanes iqala ngokuvumelanisa futhi isikhathi sokugcina singahluka.
Iwashi kufanele libe kumodi yesivinini esikhulu
Inqubo yokudlulisa ngaphansi kokusebenza kwemodi ngayinye
Inqubo yokungena kumodi yokubalekela: LP-11- LP-10- LP-00-LP-01-LP-01-LP-00-Ikhodi Yokungena-LPD (10MHz)
