neural network technology has developed rapidly and reached a level comparable to human recognition in the field of image recognition. Traditional convolutional neural networks usually require GPU with high energy consumption in the training and recognition stage
so they cannot be applied to mobile applications requiring small and low-power devices. This paper presents a neuromorphic hardware architecture of spiking convolutional neural networks for recognizing handwriting numbers. Because the neuromorphic only operates when there is a spike input
it can achieve a low power consumption accordingly. When recognizing the MNIST data set
the accuracy of the traditional convolution neural network is 99.0%
whereas the accuracy of the neuromorphic hardware is 98.46%. Therefore
the neuromorphic hardware achieved a comparable recognition accuracy while lowering down the power consumption greatly compared to CNN with a similar hardware architecture.
