ARM is UK afaik and Huawei is not banned in UK. Maybe after brexit US will force UK to ban Huawei in return for a trade deal (IF brexit goes through and I always maintained that brexit would never happen)
Owned by a japanese parent company, HQ'd in the UK, designed and, I assume, patent filed in the US, texas iirc
I didn't know they were owned by a Japanese company. Which makes this even weirder because Japan is really anti-Huawei. They were the first to ban Huawei.
It's currently a subsidiary of Softbank Japan.
some chips are designed in Austin and San Jose but Cambridge is not only a business HQ
