%X Deep Neural Networks (DNNs) have been successfully  applied to various real-world machine learning applications.  However, performing large DNN inference tasks in real-time  remains a challenge due to its substantial computational costs. Recently, Spiking Neural Networks (SNNs) have emerged as an alternative way of processing DNN’s task. Due to its eventbased, data-driven computation, SNN reduces both inference latency and complexity. With efficient conversion methods from traditional DNN, SNN exhibits similar accuracy, while leveraging many state-of-the-art network models and training methods. In this work, an efficient neuromorphic hardware architecture for image recognition task is presented. To preserve accuracy, the analog-to-spiking conversion algorithm is adopted. The system aims to minimize hardware area cost and power consumption, enabling neuromorphic hardware processing in edge devices. Simulation results have shown that, with the MNIST digit recognition task, the system has achieved ×20 reduction in terms  of core area cost compared to the state-of-the-art works, with an accuracy of 94.4%, core area of 15 μm2 at a maximum frequency of 250 MHz.
