#中国新型芯片绕开光刻机限制# 中国新型芯片问世了！ 北京大学孙仲教授团队研究出的这个基于阻变存储器的高精度、可扩展模拟矩阵计算芯片，意义很大， 说白了就是换了个路子做计算，来绕开光刻机的限制。 以前模拟计算因为"算不准"而被淘汰，现在他们一举解决了这个老大难问题。这样一来，芯片做矩阵计 算时，速度更快、更省电，而且用28纳米这种成熟工艺就能造，不用去挤高端光刻机的独木桥。 眼下芯片还在实验阶段，适合中等规模的任务，比如应用于6G和机器人等，他们还计划两年内把芯片 规模做大，先在这些领域做起来。 长远看，它是为AI大模型训练、超算这些"算力吞金兽"准备的一个高能效后备方案。等这些需求爆发 时，咱们手里就有现成的技术牌可以打了。 2017 11 专访 北大孙仲团队 支撑6G和AI训练,可在28纳米 及以上成熟工艺量产 ...

当AI时代算力集群规模正逐步从万卡向十万卡、百万卡甚至千万卡升级时，一支中国团队悄然另辟蹊径。 今年10月，北京大学人工智能研究院/集成电路学院双聘助理教授孙仲与北京大学集成电路学院蔡一茂教授、王宗巍助理教授率领的团队成功研制出基于 阻变存储器的高精度、可扩展模拟矩阵计算芯片，在全球范围内首次将模拟计算的精度提升至24位定点精度，让未来同等任务下使用更少的计算卡成为可 能。 这是一种完全不同于目前所有商用量产芯片的新型芯片，计算精度从1%跃升至千万分之一；可以支撑6G、具身智能及AI大模型训练等多个前沿场景；更 重要的是，它可在28纳米及以上成熟工艺量产，绕开光刻机"卡脖子"环节。 事实上，AI大模型、具身智能、6G等应用背后都是矩阵计算，AI推理是做矩阵乘法，AI训练是在解矩阵方程。而英伟达的崛起正是得益于GPU（图形处 理器）很擅长做矩阵计算。 但如今摩尔定律趋于终结，晶体管很难再微缩，所以业界现在只能横向堆计算卡：少则百卡，多则万卡、十万卡。但这样的方式我认为是不可持续的—— 能耗、碳排放均呈指数级上升，与国家"双碳"目标相悖。因此，我认为需要探索一种不同的计算范式，即模拟（类比）计算。 模拟计算并非全 ...
