Core-1126-JD4 High-Performance AI Vision Core Board

Equipped with a high-performance quad-core AI vision processor with built-in AI neural network acceleration NPU, the core board has capable computing power up to 2.0 Tops, which can achieve efficient face recognition and detection; it supports multi-channel video coding and decoding and provides various interfaces. It can be flexibly applied to face recognition, gesture recognition, gate access control, and other fields.

Quad-core AI vision processor

Low-consumption AI vision processor RV1126, with a 14nm lithography process and quad-core 32-bit ARM Cortex-A7 architecture, integrates NEON and FPU — the frequency is up to 1.5GHz. It supports FastBoot, TrustZone technology, and multiple crypto engines.

High performance, high computing power

Built-in neural network processor NPU with computing power up to 2.0 Tops realizes that the power consumption of AI computing is less than 10% of the power required by the GPU. With tools and supporting AI algorithms provided, it supports direct conversion and deployment of Tensorflow, PyTorch, Caffe, MxNet, DarkNet, ONNX, etc.

Multi-level image noise reduction

With multi-level image noise reduction, 3F-HDR and other technologies, RV1126 not only ensures the dynamic range of the scene but also meets the needs of outputting full color in darkness, making “clearly visible” a reality — more conforms to the actual demands in the security field.

4K H.265 encoding & decoding

Built-in Video CODEC supports 4K H.264/H.265@30FPS and multi-channel video encoding and decoding, meeting the needs of low bit rate, low-latency encoding, and perceptual encoding, and making the video occupancy smaller.

Exquisite and mini

Core board pins are made with gold plating technology, which is anti-corrosion. The size is only 69.6mm x 33.9mm, saving a lot of space.

Stable and reliable OS

It supports Buildroot+QT OS — occupies small space, starts fast, and provides stable and reliable operation.

Various interfaces

SODIMM 260P port is provided; I2C, SPI, UART, ADC, PWM, GPIO, USB2.0, SDIO, I2S, MIPI-DSI, MIPI-CSI, CIF, SDMMC, PHY, and other interfaces are equipped, meeting needs of more usage scenarios.

To form a high-performance mainboard

The core board can be combined with the backplane to form a complete high-performance industrial mainboard with more expansion interfaces and more powerful performance, which can be directly applied to various smart products to accelerate the product development process.

Abundant resources for customization

A complete SDK, including a cross-compiler toolchain, BSP source code, application development environment, development documents, examples, face recognition algorithms, and other resources, are provided for the users to make further customization.

Applications

It is widely used in face recognition, gesture recognition, gate access control, smart security, smart IP camera, smart doorbells/peephole, self-service terminals, smart finance, smart construction, smart travel, and other industries.
