中国工程院院士表示华为已掌握ARM架构修改 自己可以升级架构

相信大家对此前ARM停止和华为及其附属公司的业务往来的事情记忆深刻,由于涉及到芯片底层,很多人对此表示出了担忧。虽然华为和海思目前不会受太大影响,麒麟980芯片也可以继续使用和生产。但是未来ARM也不会再提供更新和升级,这无疑会让华为海思的芯片在不久之后落后于其他厂商的芯片。要知道,在这现在这个市场,稍微的落后都会没有竞争力的。

不过今天,在贵阳举行的中国国际大数据产业博览会上,中国工程院院士邬贺铨在演讲中也谈到了最近华为这件事情。他表示,华为已经拿到了ARM V8架构的永久使用权,并且已经可以很熟练的设计和修改ARM的公版架构,不一定非要ARM提供下一版本的更新,华为自己也可以升级架构。

我们知道,目前市面上对ARM公版架构有修改能力仅三家,苹果、高通和三星。其中苹果算是在多年以前就已经开始改进ARM架构,基本算是真正的自研芯片。高通和三星都被称之为魔改,还是基于ARM的公版架构堆料改进而来。可想而知,要真正的修改ARM架构是非常困难并且投入巨大的。

华为海思从一开始便走的自研的路线,但是基本上都还是在芯片设计层面,只是拿ARM公版架构的Cortex-A76核心和公版的Mali-G76核心再加上了自己开发的AI核心和基带等芯片组合成了SoC。虽然在麒麟芯片在各方面表现都不错,但实际上技术难度和苹果的A系列芯片,高通和三星魔改的芯片并不一样。其实我们本来也知道海思接下来的目标原本肯定也是要自研架构,但如今被迫于形势提前放出可能会出现准备不充分的情况。这样的话其实还不如用已经获得授权的Cortex-A76架构再多坚持一段时间,再优化一番坚持两年问题不大。

由于ARM几乎已经统治了移动设备,是各种移动设备的最底层,所以华为目前也只能修改和优化ARM的架构,要想真正的自研还尚需时日。不过近来已经曝光华为的全平台系统鸿蒙或许可以让底层架构的改动来得更快一些,毕竟是一个新的系统,系统和底层架构的结合可以更好。

目前各种计算平台都已经趋于成熟,底层架构的更新更多是为了完善一些以前留下的问题或者改进功耗控制。也就是说,功能性的更新其实可能不多了,就算ARM新的公版架构出来了,或许提升也并不会太大,或许华为自己可以自己优化到同样的程度。所以大家对于ARM一事基本可以放心了,ARM方面应该也会想要跟华为继续合作,毕竟都是商人,赚钱的事情没理由放弃的。

华为有备选方案当然好,但是备胎之所以是备胎就是因为它就是以备不时之需的。不到万不得以,芯片架构级别的改动没有必要动用。目前华为确实被美国全方位管制,芯片层面其实不用过多担心,真正更应该考虑的是其他方面。比如一些小的元器件、模拟芯片甚至小到粘合剂这样不起眼的东西,有时候越是这些不起眼的部件,越难找到同级别的备选方案。

说到最后,小编想起了任正非在之前央视采访中的表态,其实他是反对华为谁都不需要,华为什么都能自己做的说法的。毕竟目前的科技公司是真正的全球化经济,没有任何一个公司或者国家能够完全掌握所有的技术。
