MIPI interface

ʻO I. MIPI MIPI (Keʻena kaʻina hana kelepona paʻalima) he acronym no ka Interface Processor Industry Mobile.
ʻO MIPI (Mobile Industry Processor Interface) kahi maʻamau ākea no nā kaʻina noi kelepona i hoʻomaka ʻia e ka MIPI Alliance.

ʻO nā kikoʻī i hoʻopau ʻia a aia i loko o ka papahana penei: E kākau i kahi wehewehe kiʻi ma aneʻi
ELUA, KO MIPI ALLIANCE O MIPI DSI SPECIFICATION
1, wehewehe inoa
ʻO kaʻO CS o ka DCS (DisplayCommandSet) kahi hoʻonohonoho maʻamau o nā kauoha no nā modula hōʻike i ke ʻano kauoha.
DSI, CSI (DisplaySerialDisplay, CameraSerialInterface)
Hōʻike ka DSI i kahi kikowaena serial kiʻekiʻe ma waena o ka mea hana a me ka module hōʻike.
Hōʻike ʻo CSI i kahi kikowaena serial kiʻekiʻe ma waena o ka mea hana a me ka module kamera.
D-PHY: Hāʻawi i nā wehewehe papa kino no DSI a me CSI
2, DSI papa hana
Ua māhele ʻia ʻo DSI i ʻehā mau papa, e pili ana i ka D-PHY, DSI, DCS kikoʻī, hierarchical structure diagram penei:
Hōʻike ka PHY i ke ala hoʻouna, ke kaapuni hoʻokomo/puka, a me ka mīkini uaki a me ka hōʻailona.
Layer Management Lane: Hoʻouna a hōʻiliʻili i ke kahe ʻikepili i kēlā me kēia ala.
Papa Kūlana Kūlana Haʻahaʻa: E wehewehe i ke ʻano o ke kālai ʻia ʻana o nā kiʻi a me nā hoʻoholo, ʻike hewa, a pēlā aku.
Papa noi: wehewehe i ka hoʻopāpā kiʻekiʻe kiʻekiʻe a me ka hoʻokaʻawale ʻana i nā kahe ʻikepili.

E kākau i kahi wehewehe kiʻi ma aneʻi
3, Kauoha a me ke ʻano wikiō
Kākoʻo nā ʻaoʻao pili DSI i nā ʻano hana kauoha a i ʻole Video, ʻo ia ke ʻano i hoʻoholo ʻia e ke ʻano hoʻolālā peripheral ʻO ke ʻano kauoha e pili ana i ka hoʻouna ʻana i nā kauoha a me nā ʻikepili i kahi mea hoʻoponopono me kahi huna hōʻike.Hoʻomalu ʻole ka host i ka peripheral ma o nā kauoha.
Ke hoʻohana nei ke ʻano kauoha i ka ʻaoʻao ʻelua ʻaoʻao ʻO ke ʻano wikiō e pili ana i ka hoʻohana ʻana i nā kahawai kiʻi maoli mai ka host a i ka peripheral.Hiki ke hoʻouna wale ʻia kēia ʻano ma nā wikiwiki kiʻekiʻe.

No ka ho'ēmiʻana i ka paʻakikī a me ka mālamaʻana i nā kumukūʻai, hiki i nā pūnaewele wikiō wale nō ke loaʻa hoʻokahi wale nō alaʻikepili
Hoʻolauna iā D-PHY
1, D-PHY wehewehe i ka synchronous, high-speed, low-power PHY.
Aia kekahi hoʻonohonoho PHY
He ala uaki
Hoʻokahi a ʻoi aʻe paha ala ʻikepili
Hōʻike ʻia ka hoʻonohonoho PHY no nā Alanui ʻelua ma lalo nei
E kākau i kahi wehewehe kiʻi ma aneʻi
ʻEkolu ʻano ala nui
Uaki ala hookahi Lane
Alanui ʻikepili ʻaoʻao hoʻokahi
ʻElua ala ʻike Lane
ʻO ke ʻano hoʻoili D-PHY
Ka mana haʻahaʻa (Low-Power) ʻano hōʻailona (no ka mana): 10MHz (max)
ʻO ke ʻano hōʻailona kiʻekiʻe (no ka lawe ʻana i ka ʻikepili kiʻekiʻe): 80Mbps i 1Gbps/Lane
Hōʻike ka protocol haʻahaʻa haʻahaʻa D-PHY ʻo ka ʻāpana liʻiliʻi o ka ʻikepili he byte
I ka hoʻouna ʻana i ka ʻikepili, pono e haʻahaʻa i mua a kiʻekiʻe ma hope.
D-PHY no nā polokalamu kelepona
DSI: Hōʻike i ke kikowaena serial
Hoʻokahi ala uaki, hoʻokahi a ʻoi aʻe paha ala ʻikepili
CSI: Kamehana Serial Interface
2, Alanui module
Aia ka PHY me D-PHY (Lane Module)
Aia paha iā D-PHY:
Mea hoʻolele mana haʻahaʻa (LP-TX)
Mea lawe mana haʻahaʻa (LP-RX)
Mea hoʻolele kiʻekiʻe (HS-TX)
Loaʻa ka māmā holo kiʻekiʻe (HS-RX)
Mea ʻimi hoʻokūkū mana haʻahaʻa (LP-CD)
ʻEkolu ʻano ala nui
Uaki ala hookahi Lane
Kumu: HS-TX, LP-TX
Kauā: HS-RX, LP-RX
Alanui ʻikepili ʻaoʻao hoʻokahi
Kumu: HS-TX, LP-TX
Kauā: HS-RX, LP-RX
ʻElua ala ʻike Lane
Haku, Kauā: HS-TX, LP-TX, HS-RX, LP-RX, LP-CD
3, Moku'āina a me ka uila
Mokuʻāina ʻo Lane
LP-00, LP-01, LP-10, LP-11 (hoʻokahi-hopena)
HS-0, HS-1 (ʻokoʻa)
Volta o ke ala (maʻamau)
LP: 0-1.2V
HS: 100-300mV (200mV)
4, ke ano hana
ʻEkolu mau ʻano hana no ka Lane Data
ʻO ke ʻano heʻe, ke ʻano kiʻekiʻe, ke ʻano hoʻomalu
ʻO nā hanana hiki mai ke kūlana hoʻomaha o ke ʻano mana:
Noi o ke ano pakele (LP-11-LP-10-LP-00-LP-01-LP-00)
Noi ʻano kiʻekiʻe kiʻekiʻe (LP-11-LP-01-LP-00)
Noi hoʻohuli (LP-11-LP-10-LP-00-LP-10-LP-00)
He hana kūikawā o ka Lane ʻikepili ma ka mokuʻāina LP
Ma kēia ʻano, hiki iā ʻoe ke komo i kekahi mau hana hou: LPDT, ULPS, Trigger
Hoʻokomo ka ʻIke ʻIke i ke ʻano Pakele ma o LP-11- LP-10-LP-00-LP-01-LP-00
I ka manawa ma ke mode mode Escape, pono e hoʻouna ka mea hoʻouna i ke kauoha 1 8-bit i pane i ka hana i noi ʻia
Hoʻohana ke ʻano heʻe i ka Spaced-One-Encoding Hot
Mokuʻāina Mana Loa-Haʻahaʻa
Ma kēia moku'āina, nele nā ​​laina (LP-00)
ʻO ke kūlana mana haʻahaʻa loa o Clock Lane
Hoʻokomo ka Clock Lane i ka mokuʻāina ULPS ma o LP-11-LP-10-LP-00
- Haʻalele i kēia mokuʻāina ma o LP-10 , TWAKEUP , LP-11, ʻo ka manawa TWAKEUP liʻiliʻi he 1ms
Kiʻekiʻe-wikiwiki hoʻoiliʻikepili
ʻO ka hana o ka hoʻouna ʻana i ka ʻikepili serial kiʻekiʻe i kapa ʻia ka hoʻoili ʻikepili kiʻekiʻe kiʻekiʻe a i ʻole triggering (burst)
Hoʻomaka like nā puka Lanes a ʻokoʻa paha ka manawa hope.
Pono ka uaki ma ke ʻano holo wikiwiki
ʻO ke kaʻina hana hoʻoili ma lalo o kēlā me kēia hana mode
Ke kaʻina hana o ke komo ʻana i ke ʻano Pakele: LP-11- LP-10- LP-00-LP-01-LP-01-LP-00-Komo Komo-LPD (10MHz)
Ke kaʻina hana o ka puka ʻana i ke ʻano Pakele: LP-10-LP-11
ʻO ke kaʻina hana o ke komo ʻana i ke ʻano wikiwiki kiʻekiʻe: LP-11- LP-01-LP-00-SoT (00011101) - HSD (80Mbps a 1Gbps)
ʻO ke kaʻina hana o ka haʻalele ʻana i ke ʻano holo wikiwiki: EoT-LP-11
Mana hoʻomalu – BTA kaʻina hana: LP-11, LP-10, LP-00, LP-10, LP-00
Ke ʻano hoʻomalu – BTA loaʻa kaʻina hana: LP-00, LP-10, LP-11

Kiʻi hoʻololi mokuʻāina
