The Neural-Network Accelerators (NACC) improves the inference performance of neural networks. The NACC data type is INT8, and supports im2col, convolution, depthwise convolution, average pool, max pool, fully connected, activation and matrix multiplication acceleration. Such as can accelerate ResNet, MobileNet, Alexnet, VGG16, YOLO and other structures of the network. This IP can be used as a accelerator for functions in NMSIS, the open-source TensorFlow Lite.
