OK how hard would that be? I'm mostly reading that Huawei's entire design is based on ARM so moving to RISC V sounds like everything has to be redesigned from the basics. Is that correct or is it much easier than that?
So I added this thought into my last comment after you replied. What do you think about this:
That makes me question whether some other Chinese company can purchase ARM9 and cue Huawei in as to how to improve ARM8 if Huawei is having an issue doing it alone. Obviously they cannot copy or it would be copyright infringement but a push in the right direction, or a blueprint to modify until it can be argued that it is not the same thing can be very helpful I think.
It is a bad idea to move the smartphones out of ARM because of the dependency Android has on that architecture. You also have a vast software library of Android/ARM applications you would need to port. Intel tried competing with ARM a couple years back and it was a total failure.
Where China can replace ARM, if it comes to that, is in servers where that problem is greatly diminished.
Huawei would still need an ARM architecture license to produce and sell chips and products with them outside of China.
But, like I said, I think the news reports we are getting are lots of hyperbole. Most of ARM's development is made in Europe.
Until we know more about what really is the case, in terms of restrictions and limitations, it is too early to tell.
Don't fall into the trap of this media war.
It think it is more likely that ARM will totally drop its operations in the US market than Huawei will get totally blocked from using their technology.
At best some restrictions on use of certain US designs might be made.
