Samfara MIPI Interface, Protocol, da Standards: Jikinsa Da Aiki

Kuna daidaita a cikin shirin daga cikin wannan suna daidai, wata shirya ta fitar daidai ga kasuwar mobile yan kuma alamun electronics yana gabatar da shirya ta fitar daidai ga cikin wannan shirya. Daga cikin wannan, teknolojin MIPI (Mobile Industry Processor Interface) yana iya yi amfani da sabon hanyoyi a cikin wannan shirya, ya kamata masu rarrabe ne a cikin wannan shirya da ido da ido. Wannan makala mai tsarin suna za'a iya bayyana wannan shirya MIPI, protocol, kuma standards, kuma wannan rubutu na farko ne a cikin wannan zaman nan electronics.

1.Matsayin MIPI?

MIPI, ko Mobile Industrial Processor Interface, ya ci gaba da rubutun aikin da aka rayuwa daga MIPI Alliance don tsaye masu kawo wani a cikin mobile devices. Rubutun na yanzu ne daidai a kan shirya tare da hanyar lowa, high-speed da mutum, kuma ya ta fi ma'aikata a cikin mobile devices mai tsaye mai rubutunin smartphones da tablets. Rubutun ne daidai a kan samfara high-speed data transfer binciken mobile devices da alamun rubutun. MIPI Alliance ya zauna 2003 daga industry leaders don rayuwa da iya fuskawa open standards don interfaces a cikin mobile da mobile-affected industries.

2.Fahimta MIPI Interface

Interface a cikin electronics ne gabatar da aka share da aka yi amfani da rubutun. Suna da sabon ranar MIPI interfaces, mai shugaban MIPI-CSI2, MIPI D-PHY, MIPI C-PHY, MIPI M-PHY, da MIPI I3C. Sabon interface ya kawo amfani daidai da bayanin karakteristikinsa a cikin data rate, power consumption, da physical layer implementation.

• MIPI CSI (Camera Serial Interface): Ana amfani dashi don haɗa na'urori masu auna firikwensin kyamara zuwa masu sarrafawa, yana ba da damar watsa bayanai na hoto mai sauri.

Kawai naɗa za'a cikakken a cikin zomai, tableta, da wani aiki na kusar, ina ke duniya ba haifuwa da sauran rayuwar rubutu ba.

2.1Taimakon MIPI Protocol

mipi protocol  sunace wannan suna daidaita masu shirin gudanar data. Wannan mipi- protocol ya kamata:

• MIPI CSI-2 (mipi camera serial interface) : Ya ke da aka yi a cikin mipi connector don haɗin kyamara, yana tallafawa na'urori masu auna hoto masu girma da aikace-aikacen bidiyo. Yana tabbatar da ƙananan amfani da wutar lantarki da kuma watsa bayanai mai kyau.
• MIPI DSI-2 (mipi display serial interface) :An tsara shi don fuskokin nuni, yana tallafawa allon babban ma'ana kuma yana haɓaka ƙwarewar gani tare da ƙarancin jinkiri da babban bandwidth.

Rubutun MIPI an bai daidai ba daga wannan tsarin gaba, kuma an saukeƙe wani haɗa da hanyar bakwai da yanzu. An saukewa taimakon daidai na fitarwa.

2.2Rubutun MIPI

Rubutu ne kan zuwa aiki da hanyar bakwai. Rubutu kuskuren MIPI an sune:

• MIPI CSI-2: Yana bayyana keɓaɓɓen keɓaɓɓen kamara, yana tallafawa ƙuduri har zuwa 8K.

• MIPI UniPro: Matsayi mai mahimmanci don haɗa haɗin tsarin daban-daban a cikin na'urar.

Ko'owar shirin nan suna ake danna da wani a cikin wannan kuma yanzu, ya ke yi amfani da hanyar binciken da taimakon gudanarwa.

2.3Taswira MIPI

Taswiran sistemins MIPI an yi designe a ciki masu amfani da rubutu naɗa. Kullum mai tsarin dai dai an sune:

• Matsayin: An samfuna rubutu da fatan a cikin komponan.
• Physical Layers (PHY): Tabbatar da siginar siginar da za a iya dogara.
• Protocol Layers: Gudanar da dokokin musayar bayanai.

Taswiran rubutun nan ya enable amfani da hanyar binciken da taimakon gudanarwa a cikin jumla mai komponan a cikin wani ayyuka.

3. Wannan miyan cameran MIPI ana so?

Yanzu, goma daidai al'umarni daga karkashin smartphone suna zuciya na kamera. A cikin wannan shirye, wanda suka yi amfani da smartphone ne a kananƙwarwa suka zuciya na kamera. A cikin lokaci daidai na media sosayal, kamera mobile biyu shi ake samun wannan duniya da aka yi amfani da shi.

Sensar kamera don yadda suka iya samun MIPI interface suka nuna da MIPI cameras. Kamar suka bukatar da fi sakin smartphones, tablets, laptops da cikakken daidai na al'amari.

Shirye vision system don mobile devices ya kamata wannan rubutu:

• Sensar Imaji: Wannan rubutu ya bincika hanyar kira rayuwarwa da hanyar shi ya yi amfani da shi a kan digitize.
• MIPI interface: Wannan keɓaɓɓen aikin yana aiki ne a matsayin gada tsakanin firikwensin kyamara da mai sarrafawa. MIPI wani keɓaɓɓen keɓaɓɓen keɓaɓɓen keɓaɓɓen keɓaɓɓen keɓaɓɓen keɓaɓɓen keɓaɓɓen keɓaɓɓen keɓaɓɓen keɓaɓɓen keɓaɓɓen keɓaɓɓen keɓaɓɓen keɓaɓɓen keɓaɓɓen keɓaɓɓen keɓaɓɓen keɓa

Kuna faruwarwa, MIPI ya so daidaita a cikin wannan lokaci, an yi tsarin daidaita kuma bayar daudawa a cikin samfoti.

Saba Fafan:

An zaka ce wannan suna ne MIPI C-PHY ko D-PHY?

MIPI C-PHY an yi samin jinsi na tsarin kodin da aka yi amfani da sabon ruwa ci gaba kuma pins daidai. MIPI D-PHY an yi amfani da differential signaling, wadannan ya simpler kuma ya kamata pins daidai don sabon ruwa.

Kana amfani MIPI interfaces a cikin designs na zuciya?

Fafanin shirye MIPI ta hanyar kula rubutun MIPI a ce, tsaye masu kula daidaita, da nuna compliance don MIPI standards don performance daidai da kuma interoperability.
