2. Core Advantages of RV1126B
2.1 64-bit High-Efficiency CPU Architecture
The upgrade from 32-bit Cortex-A7 to 64-bit Cortex-A53 enables faster system response, smoother multi-tasking (e.g., video encoding + AI analysis + network transmission), and support for 4GB large memory, laying a solid foundation for complex application scenarios.
2.2 50% Higher AI Computing Power
With 3 TOPS NPU, RV1126B runs AI models (e.g., object detection, face recognition, anomaly analysis) 50% faster than RV1126. It supports mainstream frameworks (TensorFlow, PyTorch, Caffe) and INT8/INT16 hybrid operations, meeting the requirements of multi-model and high-precision AI applications.
2.3 AI-ISP + Multi-Camera Synchronous Processing
The built-in AI-ISP works independently of the NPU, implementing low-light enhancement (0.01Lux), HDR, 3DNR, and fisheye correction. It supports 4-channel MIPI-CSI synchronous input, enabling multi-camera stitching, panoramic monitoring, and stereo vision applications.
2.4 Rich High-Speed Interfaces
· USB 3.0: 10Gbps ultra-fast transmission for high-definition video and large data storage.
· Gigabit Ethernet: Stable high-speed network for real-time video streaming and remote management.
· CAN FD: Industrial-grade bus for automotive and industrial control scenarios.
· Integrated Audio Codec & RTC: Reduces peripheral BOM cost and simplifies design.
2.5 Low Power Consumption & Always-On Vision (AOV)
The optimized power architecture reduces typical power consumption to 2.8W, with AOV standby power as low as 1mW. It supports 7×24h abnormal sound (bark, glass breakage) wake-up and video-audio synchronous monitoring, suitable for low-power and long-term standby scenarios.
