提出一款双模式ADAS SoC,支持高性能驾驶模式(d-mode)和超低功耗停车模式(p-mode),通过RNN-FIS意图预测引擎智能触发监控记录,延长电池寿命。解决了汽车黑盒系统在停车模式下持续录像导致电池耗尽的问题。
forward-collision warning, advanced emergency braking, adaptive cruise control, and lane-keeping assistance. Recently, automotive black boxes are installed in cars for tracking accidents or theft. In this paper, a dual-mode ADAS SoC is proposed to support both high-performance ADAS functionality in drivingmode (d-mode) and an ultra-low-power black box in parking-mode (p-mode). By operating in p-mode, surveillance recording can be triggered intelligently with the help of our intention-prediction engine (IPE), instead of always-on recording to extend battery life and prevent discharge. Most ADAS functions require semi-global matching (SGM) for precise distance estimation due to its high accuracy depth map [1]. However, an SoC
