MIPI interface

I. MIPI MIPI (Mobile Industry Processor Interface) ichidimbu cheMobile Industry Processor Interface.
MIPI (Mobile Indasitiri Processor Interface) ndeye yakavhurika chiyero che mobile application processors yakatangwa neMIPI Alliance.

Zvinotsanangurwa zvakapedzwa uye zviri muchirongwa ndeizvi: Nyora tsananguro yemufananidzo pano
CHECHIPIRI, MIPI ALLIANCE'S MIPI DSI KUTAURA
1, dudziro yezita
TheCS yeDCS (DisplayCommandSet) iri seti yakamisikidzwa yemirairo yemamodule ekuratidzira mune yekuraira mode.
DSI, CSI (DisplaySerialDisplay, KameraSerialInterface)
DSI inotsanangura yakakwira-kumhanya serial interface pakati pe processor uye module yekuratidzira.
CSI inotsanangura yakakwira-kumhanya serial interface pakati pe processor uye kamera module.
D-PHY: Inopa chimiro chemuviri tsananguro yeDSI neCSI
2, DSI akaturikidzana chimiro
DSI yakakamurwa kuita zvidimbu zvina, zvinoenderana neD-PHY, DSI, DCS yakatarwa, hierarchical chimiro dhizaini sezvinotevera:
PHY inotsanangura svikiro rekutapurirana, yekupinza/kubuda dunhu, uye wachi nechiratidzo meshini.
Lane Management Layer: Tumira uye utore kuyerera kwedata kune imwe neimwe nzira.
Yakaderera Level Protocol layer: Inotsanangura kuti mafuremu uye zvigadziriso zvinogadzirwa sei, kuona kukanganisa, zvichingodaro.
Chishandiso layer: Inotsanangura yakakwirira-level encoding uye parsing data inoyerera.

3, Raira uye Vhidhiyo Modhi
DSI-inoenderana peripherals inotsigira Command kana Vhidhiyo inoshanda modhi, iyo modhi inotarwa neiyo peripheral architecture Command mode inoreva kutumira mirairo uye data kune controller ine cache yekuratidzira.Mubati anodzora zvisina kunanga peripheral kuburikidza nemirairo.
Kuraira modhi inoshandisa maviri-nzira interface Vhidhiyo modhi inoreva kushandiswa kweiyo chaiyo-chifananidzo nzizi kubva kumubati kuenda kuperipheral.Iyi modhi inogona kufambiswa chete nekumhanya kwakanyanya.

Kuti uderedze kuomarara uye kuchengetedza mutengo, vhidhiyo-chete masisitimu anogona kunge aine nzira imwe chete yedata
Nhanganyaya kune D-PHY
1, D-PHY inotsanangura synchronous, high-speed, low-power, low-cost PHY.
Kugadziriswa kwePHY kunosanganisira
Mukoto wewachi
Imwe kana kupfuura data nzira
Iyo PHY kumisikidzwa kwemaLane maviri inoratidzwa pazasi

Imwe-nzira data Lane
Nzira mbiri-dhata Lane
D-PHY nzira yekufambisa
Yakaderera-simba (Yakaderera-Simba) chiratidzo modhi (yekutonga): 10MHz (max)
High-speed signal mode (yepamusoro-speed data transmission): 80Mbps kusvika 1Gbps/Lane
Iyo D-PHY yakaderera-level protocol inotsanangura kuti iyo shoma unit yedata ndeye byte
Pakutumira data, inofanira kunge yakaderera pamberi uye yakakwirira kumashure.
D-PHY yemafoni ekushandisa
DSI: Ratidza serial interface
Imwe wachi yenzira, imwe kana kupfuura data nzira
CSI: Kamera Serial Interface
2, Lane module
PHY ine D-PHY (Lane Module)
D-PHY inogona kunge iine:
Low-power transmitter (LP-TX)
Yakaderera-simba inogamuchira (LP-RX)
High-speed transmitter (HS-TX)
High-speed receiver (HS-RX)
Low-simba Competitive Detector (LP-CD)

4, maitiro ekushanda
Matatu ekushandisa maitiro eData Lane
Escape mode, High-Speed ​​mode, Control mode
Zviitiko zvinogoneka kubva pakumira mamiriro ekudzora maitiro ndeaya:
Chikumbiro chekutiza (LP-11-LP-10-LP-00-LP-01-LP-00)
Chikumbiro cheHigh-Speed ​​mode (LP-11-LP-01-LP-00)
Chikumbiro chekuchinja (LP-11-LP-10-LP-00-LP-10-LP-00)
Escape mode ibasa rakakosha re data Lane muLP state
Mune iyi modhi, unogona kuisa mamwe mabasa ekuwedzera: LPDT, ULPS, Trigger
Data Lane inopinda Escape mode kuburikidza neLP-11- LP-10-LP-00-LP-01-LP-00
Kamwe muEscape mode modhi, mutumiri anofanira kutumira 1 8-bit kuraira mukupindura kune chakumbirwa chiito
Escape mode inoshandisa Spaced-One-Encoding Hot
Ultra-Low Power State
Munzvimbo iyi, mitsetse haina chinhu (LP-00)
Iyo yekupedzisira-yakaderera simba mamiriro eClock Lane
Clock Lane inopinda muULPS state kuburikidza neLP-11-LP-10-LP-00
- Buda mudunhu rino neLP-10, TWAKEUP, LP-11, nguva shoma yeTWAKEUP i1ms
High-speed data transmission
Chiito chekutumira yakakwira-kumhanya serial data inonzi yakakwira-kumhanya dhata kufambisa kana kukonzeresa (kuputika)
All Lanes magonhi anotanga synchronously uye nguva yekupedzisira inogona kusiyana.
Wachi inofanira kunge iri mu high-speed mode
Iyo yekuchinjisa maitiro pasi pega yega modhi kushanda
Maitiro ekupinda Escape mode: LP-11- LP-10- LP-00-LP-01-LP-01-LP-00-Entry Code-LPD (10MHz)
