Chapter 1  Introduction 
1.1 Overview 
RK3399 is a low power, high performance processor for computing, personal mobile 
internet devices and other smart device applications. Based on Big.Little architecture, it 
integrates dual-core Cortex-A72 and quad-core Cortex-A53 with separate NEON 
coprocessor. 
Many embedded powerful hardware engines provide optimized performance for high-end 
application. RK3399 supports multi-format video decoders including H.264/H.265/VP9up 
to4Kx2K@60fps, especially, H.264/H.265 decoders support 10bits coding, and also 
supports H.264/MVC/VP8 encoders by 1080p@30fps, high-quality JPEG encoder/decoder, 
and special image preprocessor and postprocessor. 
Embedded 3D GPU makes RK3399 completely compatible with OpenGL ES1.1/2.0/3.0/3.1, 
OpenCL and DirectX 11.1. Special 2D hardware engine with MMU will maximize display 
performance and provide very smooth operation. 
RK3399 has high-performance dual channel external memory interface 
(DDR3/DDR3L/LPDDR3/LPDDR4) capable of sustaining demanding memory bandwidths, 
also provides a complete set of peripheral interface to support very flexible applications. 
1.2 Features 
The features listed below which may or may not be present in actual product, may 
be subject to the third party licensing requirements. Please contact Rockchip for 
actual product feature configurations and licensing requirements. 
 
1.2.1  Microprocessor 
  Dual-core ARM Cortex-A72 MPCore processor and Quad-core ARM Cortex-A53MPCore 
processor, both are high-performance, low-power and cached application processor 
  Two CPU clusters.Big cluster with dual-coreCortex-A72 is optimized for high-
performance and little cluster with quad-core Cortex-A53 is optimized for low power. 
  Full implementation of the ARM architecture v8-A instruction set, ARM Neon Advanced 
SIMD (single instruction, multiple data) support for accelerating media and signal 
processing 
  ARMv8 Cryptography Extensions 
  SCU ensures memory coherency between the MPCore for each cluster 
  CCI500 ensures the memory coherency between the two clusters 
  Each Cortex-A72 integrates48KB L1 instruction cache and 32KB L1 data cache with 4-
way set associative. Each Cortex A53 integrates 32KB L1 instruction cache and 32kB L1 
data cache separately with 4-way set associative 
  1MB unified L2 Cache for Big cluster, 512KB unified L2 Cache for Little cluster 
  Trustzone technology support 
  Full Coresight debug solution 
  Debug and trace visibility of whole systems 
  ETM trace support 
 
Invasive and non-invasive debug 
  Eight separate power domains for CPU core system to support internal power switch 
and externally turn on/off based on different application scenario 
  PD_A72_B0: 1st Cortex-A72 + Neon + FPU + L1 I/D cache of big cluster 
  PD_A72_B1: 2nd Cortex-A72+ Neon + FPU + L1 I/D cache of big cluster 
  PD_SCU_B: SCU + L2 Cache controller, and including PD_A72_B0, PD_A72_B1, 
debug logic of big cluster 
  PD_A53_L0: 1st Cortex-A53 + Neon + FPU + L1 I/D Cache of little cluster 
  PD_A53_L1: 2nd Cortex-A53 + Neon + FPU + L1 I/D Cache of little cluster
