摘要: 存内计算突破了传统冯诺依曼瓶颈,实现了存储单元与逻辑单元的融合,是实现智能计算的主要技术路线之一。当前的存内计算技术主要面临着硬件资源复用、存内计算单元设计和模拟运算实现等关键挑战亟待解决。随着技术的演进,存内计算凭借其低功耗、高响应速度等性能优势,将首先在物联网的终端推理场景得到应用。存内计算的硬件载体也将从NORFlash 向新型非挥发存储器件方向逐步转变。

Abstract: Computing In-Memory (CIM) is a hardware accelerating approach for AI algorithm, which overcomes the bottleneck of traditional Von Neumann architecture and realizes the cooperation of memory unit and logic unit. At present, CIM faces many key challenges, such as hardware resources reuse, cell design and analog computation.With the development of technology, CIM, with its excellent low power consumption and high response speed, will first be applied to the End-Inference tasks in IoT scenarios. In the future, the hardware carrier of CIM will develop fromNORFlash memory to novel non-volatile memory.
