I. MIPI MIPI (Mobile Industry Processor Interface) ndi chidule cha Mobile Industry processor Interface.
MIPI (Mobile Industry Processor Interface) ndi mulingo wotseguka wama processor amafoni oyambitsidwa ndi MIPI Alliance.
Zomwe zamalizidwa ndipo zili mu dongosololi ndi izi: Lembani kufotokoza kwa chithunzi apa
CHACHIWIRI, MIPI ALLIANCE'S MIPI DSI SECIFICATION
1, kutanthauzira dzina
TheCS ya DCS (DisplayCommandSet) ndi seti yokhazikika ya malamulo a ma module owonetsera mumachitidwe olamula.
DSI, CSI (DisplaySerialDisplay, CameraSerialInterface)
DSI imatanthauzira mawonekedwe othamanga kwambiri pakati pa purosesa ndi gawo lowonetsera.
CSI imatanthauzira mawonekedwe othamanga kwambiri pakati pa purosesa ndi module ya kamera.
D-PHY: Amapereka matanthauzidwe amtundu wa DSI ndi CSI
2, mawonekedwe a DSI
DSI imagawidwa m'magulu anayi, ofanana ndi D-PHY, DSI, DCS specifications, hierarchical structure design motere:
PHY imatanthawuza sing'anga yotumizira, gawo lolowera / zotulutsa, ndi wotchi ndi makina amazidziwitso.
Lane Management Layer: Tumizani ndi sonkhanitsani kuchuluka kwa data kunjira iliyonse.
Low Level Protocol layer: Imatanthawuza momwe mafelemu ndi ziganizo zimapangidwira, kuzindikira zolakwika, ndi zina zotero.
Ntchito yosanjikiza: Imafotokozera ma encoding apamwamba kwambiri komanso mayendedwe a data.
Lembani kufotokozera chithunzi apa
3, Command and Video Mode
DSI-compatible peripherals support Command or Kanema opareshoni modes, amene mode amatsimikiziridwa ndi zotumphukira Command mode amatanthauza kutumiza malamulo ndi deta kwa wolamulira ndi posungira zowonetsera.Wolandirayo amayang'anira zotumphukira mosagwirizana ndi malamulo.
Njira yolamulira imagwiritsa ntchito mawonekedwe anjira ziwiri Mawonekedwe a kanema amatanthauza kugwiritsa ntchito mitsinje yazithunzi zenizeni kuchokera kwa omwe adalandira kupita ku zotumphukira.Mchitidwewu ukhoza kufalitsidwa pa liwiro lalikulu.
Kuti muchepetse zovuta ndikusunga ndalama, makina opangira makanema okha amatha kukhala ndi njira imodzi yokha ya data
Chiyambi cha D-PHY
1, D-PHY imalongosola synchronous, high-liwiro, mphamvu yochepa, yotsika mtengo PHY.
Kukonzekera kwa PHY kumaphatikizapo
Njira ya wotchi
Njira imodzi kapena zingapo za data
Kukonzekera kwa PHY kwa Njira ziwiri kukuwonetsedwa pansipa
Lembani kufotokozera chithunzi apa
Mitundu ikuluikulu itatu
Njira imodzi ya wotchi Lane
Njira imodzi ya data Lane
Njira ziwiri za data Lane
D-PHY njira yopatsira
Mphamvu yotsika (yotsika-Mphamvu) (yowongolera): 10MHz (max)
High-liwiro chizindikiro akafuna (kwa mkulu-liwiro kufala deta): 80Mbps kuti 1Gbps/Lane
Protocol ya D-PHY yotsika imatanthawuza kuti gawo lochepera la data ndi byte
Potumiza deta, iyenera kukhala yotsika kutsogolo ndi yokwera kumbuyo.
D-PHY yamapulogalamu am'manja
DSI: Onetsani mawonekedwe amtundu
Wotchi imodzi, njira imodzi kapena zingapo za data
CSI: Kamera seri Interface
2, gawo la njira
PHY ili ndi D-PHY (Module ya Lane)
D-PHY ikhoza kukhala ndi:
Low-power transmitter (LP-TX)
Wolandila mphamvu zochepa (LP-RX)
Ma transmitter othamanga kwambiri (HS-TX)
High-speed receiver (HS-RX)
Low-power Competitive Detector (LP-CD)
Mitundu ikuluikulu itatu
Njira imodzi ya wotchi Lane
Mphunzitsi: HS-TX, LP-TX
Kapolo: HS-RX, LP-RX
Njira imodzi ya data Lane
Mphunzitsi: HS-TX, LP-TX
Kapolo: HS-RX, LP-RX
Njira ziwiri za data Lane
Mbuye, Kapolo: HS-TX, LP-TX, HS-RX, LP-RX, LP-CD
3, Lane state ndi voltage
Lane State
LP-00, LP-01, LP-10, LP-11 (mapeto amodzi)
HS-0, HS-1 (kusiyana)
Lane voltage (yokhazikika)
LP: 0-1.2V
HS: 100-300mV (200mV)
4, ntchito mode
Njira zitatu zogwirira ntchito za Data Lane
Mawonekedwe othawa, Kuthamanga Kwambiri, Kuwongolera
Zochitika zotheka kuchokera ku stop state of control mode ndi:
Pempho la njira yothawa (LP-11-LP-10-LP-00-LP-01-LP-00)
Pempho la High-Speed mode (LP-11-LP-01-LP-00)
Pempho losinthira (LP-11-LP-10-LP-00-LP-10-LP-00)
Escape mode ndi ntchito yapadera ya data Lane mu LP state
Munjira iyi, mutha kuyika zina zowonjezera: LPDT, ULPS, Trigger
Data Lane ikulowa mu Escape mode kudzera pa LP-11- LP-10-LP-00-LP-01-LP-00
Kamodzi mu mawonekedwe a Escape mode, wotumizayo ayenera kutumiza lamulo la 1 8-bit poyankha zomwe wapempha
Njira yothawa imagwiritsa ntchito Spaced-One-Encoding Hot
Ultra-Low Power State
M'chigawochi, mizere ilibe kanthu (LP-00)
Mphamvu yotsika kwambiri ya Clock Lane
Clock Lane ilowa m'boma la ULPS kudzera pa LP-11-LP-10-LP-00
- Tulukani m'chigawochi kudzera pa LP-10, TWAKEUP, LP-11, nthawi yochepa ya TWAKEUP ndi 1ms
Kutumiza kwa data mwachangu kwambiri
Mchitidwe wotumiza deta yothamanga kwambiri imatchedwa kutumiza kwa data mwachangu kapena kuyambitsa (kuphulika)
Zitseko zonse za Lanes zimayamba mogwirizana ndipo nthawi yomaliza imatha kusiyana.
Wotchiyo iyenera kukhala yothamanga kwambiri
Kutengerapo ndondomeko pansi pa ntchito iliyonse mode
Njira yolowera njira yothawa: LP-11- LP-10- LP-00-LP-01-LP-01-LP-00-Entry Code-LPD (10MHz)
Njira yotuluka mu Escape mode: LP-10-LP-11
Njira yolowera mothamanga kwambiri: LP-11- LP-01-LP-00-SoT (00011101) - HSD (80Mbps mpaka 1Gbps)
Njira yotuluka mothamanga kwambiri: EoT-LP-11
Njira yowongolera - Njira yopatsira BTA: LP-11, LP-10, LP-00, LP-10, LP-00
Njira yowongolera - Njira yolandirira BTA: LP-00, LP-10, LP-11
Chithunzi cha kusintha kwa boma
Lembani kufotokozera chithunzi apa
Chiyambi cha DSI
1, DSI ndi mawonekedwe a Lane extensible, 1 wotchi Lane/1-4 data Lane Lane
Zotumphukira zogwirizana ndi DSI zimathandizira njira 1 kapena 2 zoyambira:
Command Mode (yofanana ndi mawonekedwe a MPU)
Kanema wamakanema (ofanana ndi mawonekedwe a RGB) - Deta iyenera kusamutsidwa mumayendedwe othamanga kwambiri kuti ithandizire kusamutsa deta mumitundu itatu
Non-Burst Synchronous Pulse Mode
Non-Burst Synchronous Event Mode
Burst mode
Njira yotumizira:
Mawonekedwe a siginecha yothamanga kwambiri (Masigino othamanga kwambiri)
Mawonekedwe azizindikiro zamphamvu zotsika (Low-Power signing mode) - njira yokhayo ya data 0 (wotchi ndi yosiyana kapena imachokera ku DP, DN).
