Among other things, "Whereas its predecessor, 2015's Cortex-A72, was drawn up in Austin, Texas, the new A73 microarchitecture was designed by a team in France, starting about three years ago"
Arm, whilst being Brit, went to the US for the A72, but France for this one. Apart from demonstrating a modern British lack of parochialism (to be applauded) does this have implications for the forthcoming Referendum? No foreigners need reply!
"Greenhalgh said ARM's mobile cores, even its 64-bit ones, will not drop their 32-bit (AArch32) mode for a long while because there's still plenty of apps out there that are 32-bit only"
This slightly surprised me - I would have expected it to be so straightforward to recompile an app for 64-bit that not much was still using 32-bit (apart from the Pi?) But that only shows my level of ignorance.
