Key Highlights
1. Microprocessor
At the heart of the Rockchip RK3588S2 is a heterogeneous octa-core CPU cluster:
Quad-core Cortex-A76 MPcore processors for high-performance workloads.
Quad-core Cortex-A55 MPcore processors for power-efficient tasks.
This big.LITTLE configuration balances performance and efficiency, while the DynamIQ Shared Unit (DSU) enables flexible workload distribution across cores. Each Cortex-A76 features 64KB L1 cache (instruction + data) and a 512KB L2 cache, while each Cortex-A55 includes 32KB L1 cache and a 128KB L2 cache. The chip also provides a shared 3MB L3 cache.
2. Graphics and Multimedia
The RK3588S2 integrates a powerful embedded 3D GPU, supporting:
1) OpenGL ES 1.1/2.0/3.2
2) Vulkan 1.2
It also comes with a specialized 2D hardware engine with MMU to optimize display performance.
For video processing, the SoC supports:
1) 8K@60fps decoding for H.265 and VP9
2) 8K@30fps decoding for H.264
3) 4K@60fps decoding for AV1
4) H.264 and H.265 encoding up to 8K@30fps
Additionally, it includes a JPEG encoder/decoder and a range of specialized pre- and post-processors for image enhancement.
3. Advanced ISP (Image Signal Processor)
The RK3588S2 introduces a hardware-based ISP capable of handling up to 48-megapixel image inputs. It integrates accelerators for advanced imaging algorithms, including:
1) HDR
2)3A (Auto-Exposure, Auto-Focus, Auto-White Balance)
3)LSC, 3DNR, 2DNR
4)Sharpening, dehaze, fisheye correction, gamma correction
This makes it particularly suitable for camera-based edge AI applications, smart surveillance, and computer vision systems.
4. AI Acceleration
One of the standout features of the RK3588S2 is its built-in NPU (Neural Processing Unit), supporting INT4/INT8/INT16/FP16 hybrid operations. With up to 6 TOPS of computing power, it provides strong performance for edge AI workloads. Furthermore, it is compatible with popular machine learning frameworks such as TensorFlow, PyTorch, MXNet, and Caffe, allowing developers to easily port and deploy AI models.
