#每日话题#1 OverviewRK3576 is a low power, high performance processor for ARM-based PC and Edge Computing
device, personal mobile internet device and other digital multimedia applications, and
integrates quad-core Cortex-A72 and quad-core Cortex-A53 with separately NEON
coprocessor.
RK3576 video decoder supports H.264, H.265, VP9, AV1 and AVS2 etc. up to 8K@30fps or
4K@120fps, and video encoder supports H.264 and H.265 up to 4K@60fps, high-quality
JPEG encoder/decoder supports up to 4K@60fps.
Embedded 3D GPU makes RK3576 completely compatible with OpenGL ES 1.1, 2.0, and
3.2, OpenCL up to 2.0 and Vulkan 1.1. Dedicated 2D hardware engine with MMU will
maximize display performance and provide very smoothly operation.
RK3576 introduces a new generation 16-Megapixel ISP (Image Signal Processor). It
implements a lot of algorithm accelerators, such as HDR, 3A, CAC, 3DNR, 2DNR,
Sharpening, Dehaze, Enhance, Debayer, Small Angle Lens-Distortion Correction and so on.
The build-in NPU supports INT4/INT8/INT16/FP16/BF16/TF32 hybrid operation. In addition,
with its strong compatibility, network models based on a series of frameworks such as
TensorFlow/MXNet/PyTorch/Caffe can be easily converted.
RK3576 supports high-performance dual channel external memory interface
(LPDDR4/LPDDR4X/LPDDR5) capable of sustaining demanding memory bandwidths, also
provides a complete set of peripheral interface to support very flexible applications.
