ADAS系統晶片
WT8911
| 【 General Description 】 |
| The WT8911 is a high performance smart camera processor for ADAS application which incorporates a 32-bit RISC CPU with DSP instruction set that operates up to 200MHz and rich vision-processing-units/interfaces such as scaler, lens correction, image mask, optical flow detection, and etc. It features ADAS functions such as LDW (Lane-Departure Warning), MOD (Moving-Object Detection), BSD (Blind-Spot Detection), RCW (Rear-Collision Warning), and etc. |
| With a small form factor BGA package, the WT8911 is perfect for smart camera for automotive application where the vision processor must be integrated into the camera module. As a stand-alone processor, the WT8911 can drastically reduce main ECU’s computing burden for time-sensitive ADAS computing. It can also act as a co-processor of WT8893S Around View Monitor (AVM) processor providing ADAS features to an AVM system. The WT8911 has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 2). |
