Title:深度学习处理器 Deep Learning Processor
Abstract:以深度学习为代表的人工神经网络是机器学习最重要的方法之一,在云端和终端都有非常广泛的应用(例如广告推荐、自动翻译、语音识别、图像识别等)。然而传统的 CPU 和 GPU 芯片在进行神经网络处理时遇到了严重的性能和能耗瓶颈。近年来,我们和 Inria 合作设计了国际上首个深度学习处理器架构,能将深度学习处理能耗降低多个数量级。相关工作获得了 ASPLOS'14 和 MICRO'14 的最佳论文奖(亚洲迄今仅有的两次获计算机体系结构顶级国际会议最佳论文),并入选了 CACM 评选的研究亮点,引起了国际同行的广泛关注。我们研制的寒武纪深度学习处理器已经应用在包括华为Mate10手机在内的千万用户终端中。
Deep learning is an important machine learning method, which is widely deployed in both cloud end and mobile end. We developed the world's first deep learning processor chip Cambricon. Currently, Cambricon IP has been deployed in tens of millions of cellphone including Huawei Mate10 and P20.

Designing an Efficient and Safe Neuromorphic Computing System
Neuromorphic computing was originally referred to as the hardware that mimics neuro-biological architectures to implement models of neural systems. The concept was then extended to the computing systems that can run bio-inspired computing models, e.g., neural networks and deep learning networks. As an alternative computing platform targeting cognitive applications, power efficiency is one of the most critical design metrics of neuromorphic computing systems. The computational efficiency of a neuromorphic computing system can be improved through innovations in both computing models and hardware designs, which also generate many interesting interactive optimizations. Very recently, the security of neural network models and the consumed data emerge as another crucial concern of neuromorphic computing systems. In this talk, we will discuss several technical approaches of designing an efficient and safe neuromorphic computing system.
