1. 行业概述 存算一体(Computing-in-Memory, CIM)技术是一种革命性的计算架构,通过将计算和存储功能集成在同一芯片中,解决了传统冯・诺依曼架构中的 “内存墙” 问题。随着人工智能、边缘计算和数据中心等领域的快速发展,存算一体技术因其高效能、低功耗的特点,成为未来计算架构的重要方向。 2. 市场驱动因素 2.1...
总体上来看,感觉今年的CIM Session没有像去年那种很多新topic涌现的感觉,更多是对之前有的topic(hybrid CIM,FP CIM,CNN + Transformer)这些问题的进一步讨论。但FP CIM的范式通过三篇异曲同工的工作对预对齐方案做了一波拨乱反正还是挺有意思的,可以等论文正式放出来后看看具体的做法。14.7提出了非神经网络的负载,...
摘要: 存内计算(CIM,Computing in Memory)是一种为缓解“内存墙”和“功耗墙”而出现的新兴架构。因CPU 处理器和存储器速度发展不均衡性,冯·诺依曼架构这类中央处理器与存储器分离的结构逐渐失去其优越性。存内计算提出以计算和存储相结合的方式来减少数据的搬移,极大地提升了计算效率。MRAM作为最有潜力的新一代...
Previous nvCIM work has focused on resistive random-access memory (RRAM) systems that use a two-dimensional (2D) layout11,12,13,14,15,16,17,18,19. But the use of 2D RRAM nvCIMs to create large-scale 3D CNNs has a number of challenges (Fig. 1a,b). Increased number of weights, ...
