MaixPy ported Micropython to K210 (a 64-bit dual-core RISC-V CPU with hardware FPU, FFT, sha256 and convolution accelerator).
It includes a general-purpose neural network processor, which can do convolutional neural network calculation at low power consumption, for example obtain the size, coordinates and types of detected objects or detect and classify faces and objects. It can load TensorFlow Light Neural Nets.
