MIPI fa'aoga

I. MIPI MIPI (Feso'ota'iga Alamanuia Fa'agasologa Fe'avea'i) ose fa'apu'upu'u mo le Fefa'ataua'iga Fa'agasologa o Alamanuia Fe'avea'i.
O le MIPI (Mobile Industry Processor Interface) o se faʻataʻitaʻiga tatala mo le faʻaogaina o talosaga feaveaʻi na amataina e le MIPI Alliance.

O faʻamatalaga ua maeʻa ma o loʻo i totonu o le fuafuaga e faʻapea: Tusi se faʻamatalaga ata iinei
LUA, MIPI ALLIANCE'S MIPI DSI FAAMATALAGA
1, faauigaina o nauna
O leCS o le DCS (DisplayCommandSet) o se seti faʻatulagaina o faʻatonuga mo faʻaaliga faʻapitoa i le faʻatonuga.
DSI, CSI (DisplaySerialDisplay, CameraSerialInterface)
O lo'o fa'amatalaina e le DSI se feso'ota'iga fa'asologa maualuga-saosaoa i le va o le processor ma le module fa'aaliga.
O lo'o fa'amatalaina e le CSI se feso'ota'iga fa'asologa maualuga-saosaoa i le va o le gaosiga ma le mea pu'e ata.
D-PHY: Tuuina atu faʻamatalaga faʻapitoa mo le DSI ma le CSI
2, fausaga faʻapipiʻi DSI
DSI ua vaevaeina i ni vaega se fa, e fetaui ma le D-PHY, DSI, DCS faʻamatalaga, faʻasologa faʻatulagaina faʻasologa e pei ona taua i lalo:
O lo'o fa'amatalaina e le PHY le ala fa'asalalau, le fa'aulu ma le fa'aulufale, ma le uati ma fa'ailoga.
Layer Pulega o Lane: Lafo ma aoina fa'amaumauga o tafega i laina ta'itasi.
Low Level Protocol layer: Fa'amatala pe fa'afefea ona fa'alavaina fa'avaa ma fa'ai'uga, su'esu'eina mea sese, ma isi.
Fa'atonuga: Fa'amatala tulaga maualuga fa'ailoga ma fa'avasega fa'asologa o fa'amaumauga.

3, Poloaiga ma Ata Vitio
DSI-fesoasoani peripherals lagolago Poloaiga po o Vitio faiga faagaoioia, o le faiga e fuafuaina e le peripheral architecture Faiga Poloaiga e faasino i le auina atu o poloaiga ma faamatalaga i se pule e iai se faʻaaliga faʻapipiʻi.E pulea le tuusao e le talimalo le peripheral e ala i poloaiga.
Fa'atonuga fa'aoga fa'aoga lua-auala Fa'ata'ita'iga Vitio fa'asino ile fa'aogaina o ata moni mai le talimalo ile pito.O lenei faiga e mafai ona faʻasalalau i luga ole saoasaoa maualuga.

Ina ia fa'aitiitia le lavelave ma fa'asaoina tau, e na'o le vitio e mafai ona tasi le auala fa'amaumauga
Folasaga ile D-PHY
