1Overview
1.1 RK3568 Introduction
RK3568 is a quad-core ARM Cortex-A55 low-power and high-performance processor designed for personal
mobile Internet devices and AIoT devices.
It provides many powerful embedded hardware engines to optimize the performance of advanced
applications. The H.264 video decoder in RK3568 supports 4K@60fps, H.265 video decoder in RK3568 supports
4K@60fps, H.264/H.265 encoder supports 1080p@60fps, and high-quality JPEG codec. RK3568 embedded 3D
GPU is fully compatible with OpenGL ES 1.1/2.0/3.2, OpenCL 2.0 and Vulkan 1.1; the special 2D hardware
engine maximizes the display performance and runs smoothly at the same time. The built-in NPU supports
INT8/INT16 mixed operation. Due to strong compatibility, network models based on a series of frameworks such
as TensorFlow/MXNet/PyTorch/Caffe can be easily converted.
There are high-performance external memory interfaces in RK3568 to ensure high-capacity and high-
stability system operating memory bandwidth, and it supports multiple memory models such as DDR3, DDR3L,
LPDDR3, DDR4, LPDDR4, LPDDR4X, etc.
