Core-3576JD4

Low-Power Large-Model Core Board

Powered by the Rockchip RK3576, an octa-core 64-bit AIOT processor, Core-3576JD4 features an advanced lithography process to deliver high
performance while maintaining low power consumption. It is equipped with an ARM Mali G52 MC3 GPU and a 6 TOPS NPU. This core board
supports the private deployment of ultra-large-scale parameter models under the Transformer architecture, custom operator development, and
Docker container management technology. With support for 4K@120fps decoding/4K@60fps encoding, it boasts a display capability with 4Kresolution at a high frame rate of 120 fps. With an external watchdog, it provides industrial-grade stability.
The backplane reference design is available for deep customization.

The private deployment of large models

Octa-core 64-bit AIOT processor RK3576

RK3576, the new octa-core 64-bit high-performance AIOT processor, features a big.LITTLE architecture (4×A72 +4×A53), an advanced
lithography process, and a frequency of up to 2.2 GHz. It ensures strong support for high-performance computing and multitasking. With a
Mali-G52 MC3 GPU delivering 145G FLOPS, this GPU is capable of supporting efficient heterogeneous computing to meet the demands of
graphics-intensive applications.

4K@120fps high frame rate video decoding

It supports 8K@30fps/4K@120fps decoding (H.265/HEVC, VP9, AVS2, and AV1), 4K@60fps decoding (H.264/AVC), and 4K@60fps encoding
(H.265/HEVC and H.264/AVC).It provides HDMI 2.1 (4K@120fps)/eDP1.3 (4K@60fps) and DP1.4 (4K@120fps).

EPD display with algorithms to improve image quality

EBC output interface: E-ink EPD (Electronic Paper Display) with a resolution of up to 1920 x 2560, suitable for EINK e-readers. This core board
features RK PQ algorithms to enhance image quality, including contrast adjustment, dithering, color enhancement, brightness enhancement, and
grayscale filtering. It offers multiple refresh modes, such as global, partial, fast, ultra-fast, and continuous. With the self-developed refresh
algorithms, this device ensures swift and fluid handwriting with a minimal latency of 20ms, and supports color handwriting, delivering a better
reading experience to users.

16MP ISP with enhanced image processing capabilities

The integrated 16-megapixel ISP supports low-light noise reduction, an RGB-IR sensor, and up to 120dB of HDR. The AI-ISP enhances image quality
with reduced noise. Multi-channel MIPI-CSI input: dual MIPI CSI D-PHY (1 * 4 lanes and 2 * 2 lanes), and one MIPI CSI C/D-PHY (1 * 4 lanes).

UFS 2.0 with a data read speed of 12Gbps

With support for UFS 2.0 / HS-G3 (12Gbps), this device ensures efficient data storage and access. With the PCIe NVMe / SATA SSD expansion,
it delivers rapid data read and write speeds, enabling the device to be easily expanded to TB storage capacity.
