5月26日，针对小米自研芯片玄戒O1是向Arm定制的芯片的传言，小米手机官方微博账号回应称，这完 全是谣言，玄戒O1不是向Arm定制的，研发过程中，也没有采用Arm CSS服务。 其进一步强调，玄戒O1是小米玄戒团队，历时四年多自主研发设计的3nm旗舰SoC，其中基于Arm最新 的CPU、GPU 标准IP授权，但多核及访存系统级设计、后端物理实现完全由玄戒团队自主设计完成， 并非网传采用Arm提供的完整解决方案，所谓"向Arm定制芯片"更是违背事实的无稽之谈。 据新浪财经报道，此前ARM在其官网将小米玄戒O1称为"首款基于ARM CSS（定制服务）的芯片"，暗 示双方在架构优化层面存在深度合作。但随后官网删除相关内容。 值得注意的是，据智通财经5月26日晚间报道，Arm官网重新发布新闻稿，修改了此前"Custom Silicon"的描述，确认玄戒O1由小米自主研发。Arm在新闻稿中表示，小米全新自研芯片采用Arm架 构，标志着双方15年合作的里程碑。玄戒O1芯片由小米旗下玄戒芯片团队打造，采用最新的Armv9.2 Cortex CPU集群IP、Immortalis GPU IP和CoreLink系统互连IP， ...

过去几天，围绕着小米最新的"玄戒O1"芯片有了非常多的讨论。除了赞扬小米实现了国产 3nm芯片设计的新突破后，还有一波人围绕着小米这颗芯片是否是自研展开了激烈讨论。 进入到近日，因为Arm CSS的原因，让整个芯片圈（媒体圈）像过年一样热闹。下面，笔者 分享一下对这颗这颗风口浪尖芯片讨论的一些了解。 如果您希望可以时常见面，欢迎标星收藏哦~ 在介绍Arm CSS之前，我们先了解一下Arm的业务模式和提供的产品。 作为全球最大的IP公司，Arm在过去的大部分时间里都是通过把自己的产品"授权"给用户，收取授 权费（license ）和版税（royalty）作为主要盈利模式的。其中，授权费可以简单看作Arm将其设 计授权给你所收取的第一笔费用，至于授权的产品可以分为"Architecture license"（如苹果和高 通就是这样授权，他们可以在Arm的框架下自定义其产品）和"IP license"（就是把公司设计好的 Cortex系列处理器授权给用户）。至于版税，则简单理解为在你授权了Arm的产品并设计量产芯片 后，每卖出一颗芯片，需要支付给Arm的费用。 在过去，这也是Arm主要的营收来源。 虽然，Arm在过 ...
