[data update] Xunwei comprehensively upgraded NPU development data based on 3568 development board

With artificial intelligence , The era of big data is coming , Previously embedded processors CPU and GPU Gradually, it is difficult to meet the increasing demand , Especially in deep learning . In response to growing demand ,NPU Was born .

NPU The full English name is Neural Process Unit, Neural network processor .

To meet the needs of artificial intelligence , The processor of Ruixin micro is also gradually integrated NPU, be called RKNPU.

RKNPU After several generations of development , The first generation introduced RKNPU It's from RK3399pro and RK1808 At the beginning , Compared with traditional CPU and GPU, It has greatly improved the deep learning and operation ability . The next in RV1109 and RV1126 The second generation is used on NPU, Promoted NPU Utilization ratio . The third generation NPU Apply to RK3566 and RK3568 On , With brand new NPU Self research framework .

Ruixin micro RK3568 Chip built in NPU, yes RKNPU Representative products of the third generation . The third generation RKNPU The features are as follows ：

Equipped with a new self-developed architecture

Supports integers 8、 Integers 16 Convolution operation

Built in NPU Support INT8/INT16 Mixing operation

Inference tools support ：TensorFlow, Caffe, Tflite, Pytorch, Onnx NN, Android NN wait

the height is 1 TOPS Neural network acceleration processing performance

 

be based on iTOP-RK3568 The new implementation of the development board NPU Self research framework , It can be applied to the following scenarios through algorithm blessing ：

 

at present , Xunwei based RK3568 Development board 《iTOP-3568 Development board NPU User manual 》 Also synchronize with the new .
