ARM64 and You
First, a note on the name: the official name from ARM is "AArch64", but this is a silly name that pains me to type. Apple calls it ARM64, and that's what I will call it too.What ARM calls ARM related periphery is canonical, whether you think it's silly or not.However the overarching entity is called ARMv8, with the 64-bit state called AArch64 (which can be contrasted with the AArch32 state, which is also a part of ARMv8) and the instruction set is actually called A64.
