CORE-1126BJD4
CORE-1126BJD4 AI Vision SoM

Powered by Rockchip quad-core AI vision processor RV1126B, it integrates 3 TOPS NPU and supports mainstream large AI models and deep learning frameworks. It features a built-in 12MP ISP, an 8MP AI-ISP, and incorporates multiple algorithm accelerators. The SoM supports 12MP video encoding, 4K video decoding, and simultaneous input from 4 cameras.

AI Processor RV1126B

Powered by the quad-core 64-bit RV1126B AI vision processor. The ARM Cortex-A53-based core operates at up to 1.6 GHz and includes NEON advanced SIMD and an FPU for enhanced high-performance computing and multitasking capabilities.

Lightweight AI models

Supports lightweight large language models, large vision models, or multimodal large models under 2B parameters, such as Qwen, Gemma2-2B, Phi2, MiniCPM series, and other small-scale AI large models, meeting localized application needs in lightweight scenarios.

Built-in 12MP ISP

Equipped with a new-generation hardware-based ISP supporting up to 12MP, complete with accelerators for HDR, 3A, LSC, noise reduction, and other key algorithms. Building upon this foundation, an AI-ISP (up to 8MP), enabling superior spatial noise reduction and enhanced image processing capabilities.

4K Video Decoding

It handles video encoding at up to 12MP@30fps. Its multi-stream encoding capability allows for simultaneous high-resolution recording locally and low-resolution transmission to the cloud. It supports 4K@30fps decoding and includes an integrated JPEG codec with Baseline mode support for a variety of image sizes and YUV formats.

Input From 4 cameras

It offers support for two MIPI CSI / LVDS / SubLVDS D-PHY interfaces and one DVP (BT.601 / BT.656 / BT.1120) interface, allowing for simultaneous input from up to four cameras.

Gold-Finger Package

Featuring a gold-plated SODIMM 260-pin standard interface and a compact design, it has overall dimensions of 69.9 × 33.96 mm and weighs a mere 10g. Its small, lightweight form factor makes it easy to install and carry, enabling compatibility with a wide range of devices and application scenarios.

Robust Network Capabilities

GMAC interface enables the expansion of a Gigabit Ethernet port with TSO and USO offloading for accelerated network performance. The SDIO 3.0 interface allows for the addition of dual-band Wi-Fi (2.4GHz/5GHz), Bluetooth, as well as 4G/3G modem support.

Rich Expansion Interfaces

Boasts a wide array of I/O options, including I2C, SPI, UART, CAN, PWM, GPIO, USB 2.0, I2S, SAI, MIPI-DSI, MIPI-CSI, and DVP,，， to diverse peripheral expansion needs across different scenarios.
3 TOPS NPU Computing Power

Integrated with a 3 TOPS NPU supporting INT4/INT8/INT16/FP16 hybrid quantization, it maintains compatibility with mainstream deep learning frameworks including TensorFlow, TensorFlow Lite, PyTorch, Caffe, and ONNX. This enables intelligent data processing, voice recognition, and image analysis capabilities, meeting the demands of most edge AI applications in terminal devices.
