Abstract	Large-scale convolutional neural network (CNN), well-known to be computationally intensive, is a fundamental algorithmic building block in many computer vision and artificial intelligence applications that follow the deep learning principle. This work presents a novel stochastic-based and scalable hardware architecture and circuit design that computes a convolutional neural network with FPGA. The key idea is to implement a multi-dimensional convolution accelerator that leverages the widely-used convolution theorem. Our approach has three advantages. First, it can achieve significantly lower algorithmic complexity for any given accuracy requirement. This computing complexity, when compared with that of conventional multiplierbased and FFT-based architectures, represents a significant performance improvement. Second, this proposed stochastic-based architecture is highly fault-tolerant because the information to be processed is encoded with a large ensemble of random samples. As such, the local perturbations of its computing accuracy will be dissipated globally, thus becoming inconsequential to the final overall results. Overall, being highly scalable and energy efficient, our stochastic-based convolutional neural network architecture is well-suited for a modular vision engine with the goal of performing real-time detection, recognition and segmentation of mega-pixel images, especially those perception-based computing tasks that are inherently fault-tolerant. We also present a performance comparison between FPGA implementations that use deterministic-based and Stochastic-based architectures.
