ARM's current branding for this instruction set extension is ASIMD. Alternatively, NEON in all-caps. Either is fine with me, but if you change to ASIMD, please also change the key letter to A for ASIMD.

I'll go with A for ASIMD, I found use of of both Neon and NEON in Arm marketing material.

Are they just synonyms? We might want to say ASIMD (also known as NEON) or something similar.

Agreed, I'll change it. NEON is what its more commonly referred to afaik.
