Imigaragarire ya MIPI

I. MIPI MIPI (Imigendekere yinganda zigendanwa) ni amagambo ahinnye yimikorere yinganda zigendanwa.
MIPI.

Ibisobanuro byarangiye kandi biri muri gahunda nibi bikurikira: Andika ibisobanuro byamashusho hano
KABIRI, MIPI ALLIANCE MIPI DSI YIHARIYE
1, gusobanura izina
UwitekaCS ya DCS (DisplayCommandSet) ni urwego rusanzwe rwamabwiriza yo kwerekana module muburyo bwateganijwe.
DSI, CSI (ErekanaSerialDisplay, KameraSerialInterface)
DSI isobanura umuvuduko mwinshi wuruhererekane hagati yumutunganya na module yerekana.
CSI isobanura intera yihuta yuruhererekane hagati yumutunganya na kamera ya kamera.
D-PHY: Itanga ibisobanuro bifatika kuri DSI na CSI
2, imiterere ya DSI
DSI igabanijwemo ibice bine, bihuye na D-PHY, DSI, DCS ibisobanuro, igishushanyo mbonera cyimiterere kuburyo bukurikira:
PHY isobanura uburyo bwo kohereza, ibyinjira / ibisohoka, hamwe nisaha nuburyo bwo kwerekana ibimenyetso.
Inzira yo gucunga inzira: Kohereza no gukusanya amakuru kuri buri murongo.
Urwego rwo hasi Porotokole: Igaragaza uburyo amakadiri nicyemezo byateguwe, gutahura amakosa, nibindi.
Igice cyo gusaba: Dondora urwego rwohejuru rwerekana kodegisi no gusesengura amakuru atemba.

3, Gutegeka na Video Uburyo
DSI ihujwe na periferique ishigikira Command cyangwa Video yuburyo bukoreshwa, ubwo buryo bugenwa nububiko bwa peripheri bwububiko Amabwiriza yerekana kohereza amategeko hamwe namakuru kuri mugenzuzi ufite cache yerekana.Nyiricyubahiro agenzura mu buryo butaziguye impande zose binyuze mu mategeko.
Uburyo bwa commande bukoresha inzira-ebyiri-Imigaragarire Video yerekana ikoreshwa ryukuri-ishusho yinzira kuva kuri host kugeza kuri peripheri.Ubu buryo bushobora kwanduzwa gusa ku muvuduko mwinshi.

Kugabanya ibintu bigoye no kuzigama ibiciro, sisitemu ya videwo yonyine irashobora kugira inzira imwe gusa yamakuru
Intangiriro kuri D-PHY
1, D-PHY isobanura guhuza, kwihuta cyane, imbaraga nke, PHY ihendutse.
Ibikoresho bya PHY birimo
Umuhanda w'isaha
Inzira imwe cyangwa nyinshi
Iboneza rya PHY kumirongo ibiri irerekanwa hepfo
Andika ibisobanuro hano
Ubwoko butatu bwingenzi
Inzira imwe
Inzira imwe
Inzira ebyiri zamakuru
Uburyo bwo kohereza D-PHY
Imbaraga nke (Imbaraga-nke) uburyo bwo kwerekana ibimenyetso (kubigenzura): 10MHz (max)
Uburyo bwihuta bwikimenyetso (kubwohereza amakuru yihuse): 80Mbps kugeza 1Gbps / Umuhanda
D-PHY protocole yo murwego rwohejuru yerekana ko byibuze imibare yamakuru ari byte
Iyo wohereje amakuru, igomba kuba hasi imbere kandi hejuru inyuma.
D-PHY ya porogaramu zigendanwa
DSI: Erekana urutonde rwuruhererekane
Umuhanda umwe w'isaha, umurongo umwe cyangwa byinshi
CSI: Imigaragarire ya Kamera
2, Inzira y'umuhanda
PHY igizwe na D-PHY (Module Lane)
D-PHY irashobora kuba ikubiyemo:
Imashanyarazi nkeya (LP-TX)
Imbaraga nke (LP-RX)
Ikwirakwiza ryihuta (HS-TX)
Kwakira byihuse (HS-RX)
Ikoresha imbaraga nke zo Kurushanwa (LP-CD)
Ubwoko butatu bwingenzi
Inzira imwe
Umwigisha: HS-TX, LP-TX
Umucakara: HS-RX, LP-RX
Inzira imwe
Umwigisha: HS-TX, LP-TX
Umucakara: HS-RX, LP-RX
Inzira ebyiri zamakuru
Umwigisha, Umucakara: HS-TX, LP-TX, HS-RX, LP-RX, LP-CD
3, Umuhanda wa leta na voltage
Intara
LP-00, LP-01, LP-10, LP-11 (impera imwe)
HS-0, HS-1 (itandukaniro)
Umuyoboro wa voltage (bisanzwe)
LP: 0-1.2V
HS: 100-300mV (200mV)
4, uburyo bwo gukora
Uburyo butatu bwo gukora kuri Data Lane
Guhunga uburyo, Byihuta-byihuta, Uburyo bwo kugenzura
Ibishoboka birashoboka kuva ihagarikwa ryuburyo bwo kugenzura ni:
Guhunga uburyo bwo gusaba (LP-11-LP-10-LP-00-LP-01-LP-00)
Uburyo bwihuse bwo gusaba (LP-11-LP-01-LP-00)
Gusaba guhinduka (LP-11-LP-10-LP-00-LP-10-LP-00)
Guhunga uburyo nigikorwa kidasanzwe cyamakuru Lane muri leta ya LP
Muri ubu buryo, urashobora kwinjiza imirimo yinyongera: LPDT, ULPS, Imbarutso
Inzira ya Data yinjira muburyo bwo guhunga ikoresheje LP-11- LP-10-LP-00-LP-01-LP-00
Bimaze guhunga uburyo bwo guhunga, uwayohereje agomba kohereza 1 8-bit itegeko asubiza kubikorwa byasabwe
Guhunga uburyo bukoresha Umwanya-umwe-Encoding Ashyushye
Imbaraga zidasanzwe
Muri iyi leta, imirongo irimo ubusa (LP-00)
Imbaraga zidasanzwe cyane za Clock Lane
Isaha yisaha yinjira muri leta ya ULPS ikoresheje LP-11-LP-10-LP-00
- Sohoka muriyi leta ukoresheje LP-10, TWAKEUP, LP-11, igihe ntarengwa cya TWAKEUP ni 1ms
Kohereza amakuru yihuse
Igikorwa cyo kohereza amakuru yihuta yuruhererekane rwitwa amakuru yihuta yohereza amakuru cyangwa gukurura (guturika)
Inzira zose zumuhanda zitangira icyarimwe kandi igihe cyanyuma gishobora gutandukana.
Isaha igomba kuba muburyo bwihuse
Ihererekanyabubasha muri buri buryo bwimikorere
Inzira yo kwinjira muburyo bwo guhunga: LP-11- LP-10- LP-00-LP-01-LP-01-LP-00-Kode yinjira-LPD (10MHz)
Inzira yo kuva muburyo bwo guhunga: LP-10-LP-11
Inzira yo kwinjira muburyo bwihuse: LP-11- LP-01-LP-00-SoT (00011101) - HSD (80Mbps kugeza 1Gbps)
Inzira yo gusohoka muburyo bwihuse: EoT-LP-11
Uburyo bwo kugenzura - inzira yo kohereza BTA: LP-11, LP-10, LP-00, LP-10, LP-00
Uburyo bwo kugenzura - BTA yakira inzira: LP-00, LP-10, LP-11

Igishushanyo mbonera cya leta

Intangiriro kuri DSI
1, DSI ni Umuhanda wagutse, isaha 1 Umuhanda / 1-4 data Umuhanda
DSI ihuza periferique ishyigikira uburyo 1 cyangwa 2 bwibanze bwo gukora:
Uburyo bwa Command (busa na MPU interineti)
Uburyo bwa Video (busa na interineti ya RGB) - Amakuru agomba koherezwa muburyo bwihuse kugirango ashyigikire amakuru muburyo 3
Non-Burst Synchronous Pulse Mode
Uburyo budasanzwe bwo guhuza ibintu
Uburyo buturika
Uburyo bwo kohereza:
Uburyo bwihuta bwerekana ibimenyetso (Uburyo bwihuta bwo kwerekana ibimenyetso)
Uburyo bwo kwerekana ibimenyetso bike (Uburyo buke bwo kwerekana ibimenyetso) - gusa umurongo wa data 0 (isaha iratandukanye cyangwa iva DP, DN).
