Abstract：Computational complexity of neural network methods is high, and its application in embedded scenarios is limited. To solve this problem, a convolutional network accelerator based on heterogeneous field programmable gate array is proposed. The sliding window is employed to accelerate the convolution calculation process, and thus the convolution process of different input and output channels can be handled. A 8 bit fixed-point accelerator is designed combining network quantization process, and the usage of computing resources is reduced. Experiments demonstrate that the proposed fixed-point accelerator achieves a higher computing speed and a lower power consumption with a less performance loss.
