Taw qhia
MIPI CSI-2 yog qhov sib txuas ntau tshaj plaws rau kev sib txuas cov koob yees duab modules rau cov txheej txheem embedded - xov tooj, drones, kev kho mob, thiab lub koob yees duab tsheb. Tsis zoo li USB, MIPI yog tsim los rau luv luv, qis-latency, high-bandwidth video. Kev nkag siabMIPI bandwidthyog qhov tseem ceeb los txhawb koj lub hom phiaj kev daws teeb meem thiab tus ncej tus nqi. Ntawm Sincere, peb tsimcmos module koob yees duabkev daws teeb meem rau ntau tshaj 30 xyoo, suav nrogMIPI lub koob yees duab moduletsim.
MIPI Bandwidth yog dab tsi?
Bandwidth yog cov ntaub ntawv siab tshaj plaws ntawm lub koob yees duab sensor mus rau lub processor, ntsuas hauvgigabits ib ob (Gbps)rau txoj kab data. MIPI CSI‑2 siv 1, 2, lossis 4 txoj kab sib txawv (ntxiv rau txoj kab moos). Txhua txoj kab feem ntau khiav ntawm 500 Mbps mus rau 2.5 Gbps. Tag nrho bandwidth=txoj kab tus nqi × tus lej ntawm txoj kab.
Common configurations:
1-kab:1.5-2.5 Gbps
2-kab:3-5 Gbps
4-kab:6-10 Gbps
A 4k drone koob yees duab modulefeem ntau siv 4 kab ntawm 1.5 Gbps (6 Gbps tag nrho) rau 4K @ 30fps.
MIPI vs. Lwm yam interfaces
| Interface | Bandwidth | Cable Ntev | Siv Case |
|---|---|---|---|
| MIPI CSI-2 | 1-10 Gbps | <30 cm | Embedded, qis latency |
| USB 2.0 | 480 Mbps ib | 3–5 m | Basic webcams |
| USB 3.0/3.1 | 5-10 Gbps | 3–5 m | High-speed USB koob yees duab |
| GigE Vision | 1 gbps ua | 100 m | Kev lag luam tshuab pom |

Kev xam yuav tsum tau Bandwidth
Raw cov ntaub ntawv tus nqi=dav × qhov siab × ntsis tob × ncej tus nqi ntxiv rau nyiaj siv ua haujlwm.
HD koob yees duab module(1280 × 720, 10-ntsis, 30fps): raw ~ 276 Mbps → nrog nyiaj siv ua haujlwm ~ 350-400 Mbps. Ib txoj kab 500 Mbps ua haujlwm.
1080p @ 60fps(10-ntsis): raw ~ 1.24 Gbps → overhead ~ 1.5 Gbps. Ib txoj kab ntawm 1.5 Gbps haum; ob txoj kab kev nyab xeeb dua.
4K @30fps(10-ntsis): raw ~ 2.49 Gbps → overhead ~ 3 Gbps. Ob txoj kab 1.5 Gbps muab 3 Gbps (borderline); plaub txoj kab ntawm 1.5 Gbps (6 Gbps) yooj yim.
4K @60fps: raw ~4.98 Gbps → overhead >5gbps ua. Xav tau 4 txoj kab ntawm 1.5 Gbps (6 Gbps) lossis 2 txoj kab ntawm 2.5 Gbps (5 Gbps).
Kev xav txog tswv yim
Txhawb nqa processor- Txheeb xyuas tus tswv tsev processor txoj kab suav thiab txoj kab siab tshaj plaws. Tsis yog txhua tus processors txhawb 4-txoj kab lossis 2.5 Gbps.
Cable Ntev- MIPI yog rau board-to-board kab hauv qab 30 cm. Ntev cables degrade teeb liab.
Autofocus-Ibautofocus usb koob yees duab modulesiv USB; autofocus commands dhau I2C, tsis cuam tshuam rau video bandwidth. MIPI modules kuj siv I2C rau kev tswj.
Kev siv Drone – A 4k drone koob yees duab modulesiv MIPI rau lub teeb yuag thiab tsis muaj zog . 4 txoj kab khiav 4K @ 30fps yooj yim.
MIPI vs USB
