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...
