And to think someone said i didn't know what i was talking about when i said that it was rumoured that ARM 32bit might be next to be dropped.This move is part of Arm's unhurried stroll away from its years-old 32-bit instruction set. Supporting only 64-bit A64 in privileged modes simplifies the design of the CPU, freeing up space on the chip die for other features or potentially reducing its power draw.
Going fully 64-bit-only – for both apps and operating systems – is "the obvious next step," Peter Greenhalgh, Arm's veep of technology, told The Register, but stressed this will "take a little longer
